spice: surface switch fast path requires same format too.
Commit "555e72f spice: rework mirror allocation, add no-resize fast path"
adds a fast path for surface switches which does't go through the full
primary surface destroy and re-recreation in case the new surface is
identical to the old one (page-flip). It checks the size only though,
but the format must be identical too. This patch adds the format check.
Commit "0002a51 ui/spice: Support shared surface for most pixman
formats" increases the chance to actually trigger this.

xen/HVM: atomically access pointers in bufioreq handling
The number of slots per page being 511 (i.e. not a power of two) means
that the (32-bit) read and write indexes going beyond 2^32 will likely
disturb operation. The hypervisor side gets I/O req server creation
extended so we can indicate that we're using suitable atomic accesses
where needed, allowing it to atomically canonicalize both pointers when
both have gone through at least one cycle.
The Xen side counterpart (which is not a functional prereq to this
change, albeit a build one) went in already (commit b7007bc6f9).

virtio: sync the dataplane vring state to the virtqueue before virtio_save
When creating snapshot with the dataplane enabled, the snapshot file gets
not the actual state of virtqueue, because the current state is stored in
VirtIOBlockDataPlane. Therefore, before saving snapshot need to sync
the dataplane vring state to the virtqueue. The dataplane will resume its
work at the next notify virtqueue.
When snapshot loads with loadvm we get a message:
VQ 0 size 0x80 Guest index 0x15f5 inconsistent with Host index 0x0:
delta 0x15f5
error while loading state for instance 0x0 of device
'0000:00:08.0/virtio-blk'
Error -1 while loading VM state
to reproduce the error I used the following hmp commands:
savevm snap1
loadvm snap1

net: don't set native endianness
commit 5be7d9f1b1452613b95c6ba70b8d7ad3d0797991
vhost-net: tell tap backend about the vnet endianness
makes vhost net always try to set LE - even if that matches the
native endian-ness.
This makes it fail on older kernels on x86 without TUNSETVNETLE support.
To fix, make qemu_set_vnet_le/qemu_set_vnet_be skip the
ioctl if it matches the host endian-ness.

device-introspect-test: New, covering device introspection
The test doesn't check that the output makes any sense, only that QEMU
survives. Useful since we've had an astounding number of crash bugs
around there.
In fact, we have a bunch of them right now: a few devices crash or
hang, and some leave dangling pointers behind. The test skips testing
the broken parts. The next commits will fix them up, and drop the
skipping.

tests: Fix how qom-test is run
We want to run qom-test for every architecture, without having to
manually add it to every architecture's list of tests. Commit 3687d53
accomplished this by adding it to every architecture's list
automatically.
However, some architectures inherit their tests from others, like this:
check-qtest-x86_64-y = $(check-qtest-i386-y)
check-qtest-microblazeel-y = $(check-qtest-microblaze-y)
check-qtest-xtensaeb-y = $(check-qtest-xtensa-y)
For such architectures, we ended up running the (slow!) test twice.
Commit 2b8419c attempted to avoid this by adding the test only when
it's not already present. Works only as long as we consider adding
the test to the architectures on the left hand side *after* the ones
on the right hand side: x86_64 after i386, microblazeel after
microblaze, xtensaeb after xtensa.
Turns out we consider them in $(SYSEMU_TARGET_LIST) order. Defined as
SYSEMU_TARGET_LIST := $(subst -softmmu.mak,,$(notdir \
$(wildcard $(SRC_PATH)/default-configs/*-softmmu.mak)))
On my machine, this results in the oder xtensa, x86_64, microblazeel,
microblaze, i386. Consequently, qom-test runs twice for microblazeel
and x86_64.
Replace this complex and flawed machinery with a much simpler one: add
generic tests (currently just qom-test) to check-qtest-generic-y
instead of check-qtest-$(target)-y for every target, then run
$(check-qtest-generic-y) for every target.

hw: do not pass NULL to memory_region_init from instance_init
This causes the region to outlive the object, because it attaches the
region to /machine. This is not nice for the "realize" method, but
much worse for "instance_init" because it can cause dangling pointers
after a simple object_new/object_unref pair.

memory: allow destroying a non-empty MemoryRegion
This is legal; the MemoryRegion will simply unreference all the
existing subregions and possibly bring them down with it as well.
However, it requires a bit of care to avoid an infinite loop.
Finalizing a memory region cannot trigger an address space update,
but memory_region_del_subregion errs on the side of caution and
might trigger a spurious update: avoid that by resetting mr->enabled
first.

- sg mappings are leaked
- rx will be stalled if a lots of packets were truncated

Revert "qdev: Use qdev_get_device_class() for -device <type>,help"
This reverts commit 31bed5509dfcbdfc293154ce81086a4dbd7a80b6.
The reverted commit changed qdev_device_help() to reject abstract
devices and devices that have cannot_instantiate_with_device_add_yet
set, to fix crash bugs like -device x86_64-cpu,help.
Rejecting abstract devices makes sense: they're purely internal, and
the implementation of the help feature can't cope with them.
Rejecting non-pluggable devices makes less sense: even though you
can't use them with -device, the help may still be useful elsewhere,
for instance with -global. This is a regression: -device FOO,help
used to help even for FOO that aren't pluggable.
The previous two commits fixed the crash bug at a lower layer, so
reverting this one is now safe. Fixes the -device FOO,help
regression, except for the broken devices marked
cannot_even_create_with_object_new_yet. For those, the error message
is improved.
Example of a device where the regression is fixed:
$ qemu-system-x86_64 -device PIIX4_PM,help
PIIX4_PM.command_serr_enable=bool (on/off)
PIIX4_PM.multifunction=bool (on/off)
PIIX4_PM.rombar=uint32
PIIX4_PM.romfile=str
PIIX4_PM.addr=int32 (Slot and optional function number, example: 06.0 or 06)
PIIX4_PM.memory-hotplug-support=bool
PIIX4_PM.acpi-pci-hotplug-with-bridge-support=bool
PIIX4_PM.s4_val=uint8
PIIX4_PM.disable_s4=uint8
PIIX4_PM.disable_s3=uint8
PIIX4_PM.smb_io_base=uint32
Example of a device where it isn't fixed:
$ qemu-system-x86_64 -device host-x86_64-cpu,help
Can't list properties of device 'host-x86_64-cpu'
Both failed with "Parameter 'driver' expects pluggable device type"

qdev: Protect device-list-properties against broken devices
Several devices don't survive object_unref(object_new(T)): they crash
or hang during cleanup, or they leave dangling pointers behind.
This breaks at least device-list-properties, because
qmp_device_list_properties() needs to create a device to find its
properties. Broken in commit f4eb32b "qmp: show QOM properties in
device-list-properties", v2.1. Example reproducer:
$ qemu-system-aarch64 -nodefaults -display none -machine none -S -qmp stdio
{"QMP": {"version": {"qemu": {"micro": 50, "minor": 4, "major": 2}, "package": ""}, "capabilities": []}}
{ "execute": "qmp_capabilities" }
{"return": {}}
{ "execute": "device-list-properties", "arguments": { "typename": "pxa2xx-pcmcia" } }
qemu-system-aarch64: /home/armbru/work/qemu/memory.c:1307: memory_region_finalize: Assertion `((&mr->subregions)->tqh_first == ((void *)0))' failed.
Aborted (core dumped)
[Exit 134 (SIGABRT)]
Unfortunately, I can't fix the problems in these devices right now.
Instead, add DeviceClass member cannot_destroy_with_object_finalize_yet
to mark them:
* Hang during cleanup (didn't debug, so I can't say why):
"realview_pci", "versatile_pci".
* Dangling pointer in cpus: most CPUs, plus "allwinner-a10", "digic",
"fsl,imx25", "fsl,imx31", "xlnx,zynqmp", because they create such
CPUs
* Assert kvm_enabled(): "host-x86_64-cpu", host-i386-cpu",
"host-powerpc64-cpu", "host-embedded-powerpc-cpu",
"host-powerpc-cpu" (the powerpc ones can't currently reach the
assertion, because the CPUs are only registered when KVM is enabled,
but the assertion is arguably in the wrong place all the same)
Make qmp_device_list_properties() fail cleanly when the device is so
marked. This improves device-list-properties from "crashes, hangs or
leaves dangling pointers behind" to "fails". Not a complete fix, just
a better-than-nothing work-around. In the above reproducer,
device-list-properties now fails with "Can't list properties of device
'pxa2xx-pcmcia'".
This also protects -device FOO,help, which uses the same machinery
since commit ef52358 "qdev-monitor: include QOM properties in -device
FOO, help output", v2.2. Example reproducer:
$ qemu-system-aarch64 -machine none -device pxa2xx-pcmcia,help

virtio-net: unbreak self announcement and guest offloads after migration
After commit 019a3edbb25f1571e876f8af1ce4c55412939e5d ("virtio: make
features 64bit wide"). Device's guest_features was actually set after
vdc->load(). This breaks the assumption that device specific load()
function can check guest_features. For virtio-net, self announcement
and guest offloads won't work after migration.
Fixing this by defer them to virtio_net_load() where guest_features
were guaranteed to be set. Other virtio devices looks fine.

target-ppc: fix vcipher, vcipherlast, vncipherlast and vpermxor
For vector instructions, the helpers get pointers to the vector register

the operand holding the result.
When emulating instructions which access the vector elements in a
non-linear way, we need to store the result in an temporary variable.
This fixes openssl when emulating a POWER8 CPU.

tcg/mips: Fix clobbering of qemu_ld inputs
The MIPS TCG backend implements qemu_ld with 64-bit targets using the v0
register (base) as a temporary to load the upper half of the QEMU TLB
comparator (see line 5 below), however this happens before the input
address is used (line 8 to mask off the low bits for the TLB
comparison, and line 12 to add the host-guest offset). If the input
address (addrl) also happens to have been placed in v0 (as in the second
column below), it gets clobbered before it is used.
addrl in t2 addrl in v0

13 lw t0,0(v0) lw t0,0(v0)
Fix by using TCG_TMP0 (at) as the temporary instead of v0 (base),
pushing the load on line 5 forward into the delay slot of the low
comparison (line 10). The early load of the addend on line 7 also needs
pushing even further for 64-bit targets, or it will clobber a0 before
we're done with it. The output for 32-bit targets is unaffected.

ide: unify io_buffer_offset increments
IDEState's io_buffer_offset was originally added to keep track of offsets
in AHCI rather exclusively, but it was added to IDEState instead of an
AHCI-specific structure.
AHCI fakes all PIO transfers using DMA and a scatter-gather list. When
the core or atapi layers invoke HBA-specific mechanisms for transfers,
they do not always know that it is being backed by DMA or a sglist, so
this offset is not always updated by the HBA code everywhere.
If we modify it in dma_buf_commit, however, any HBA that needs to use
this offset to manage operating on only part of a sglist will have
access to it.
This will fix ATAPI PIO transfers performed through the AHCI HBA,
which were previously not modifying this value appropriately.
This will fix ATAPI PIO transfers larger than one sector.

spapr_pci: fix device tree props for MSI/MSI-X
PAPR requires ibm,req#msi and ibm,req#msi-x to be present in the
device node to define the number of msi/msi-x interrupts the device
supports, respectively.
Currently we have ibm,req#msi-x hardcoded to a non-sensical constant
that happens to be 2, and are missing ibm,req#msi entirely. The result
of that is that msi-x capable devices get limited to 2 msi-x
interrupts (which can impact performance), and msi-only devices likely
wouldn't work at all. Additionally, if devices expect a minimum that
exceeds 2, the guest driver may fail to load entirely.
SLOF still owns the generation of these properties at boot-time
(although other device properties have since been offloaded to QEMU),
but for hotplugged devices we rely on the values generated by QEMU
and thus hit the limitations above.
Fix this by generating these properties in QEMU as expected by guests.
In the future it may make sense to modify SLOF to pass through these
values directly as we do with other props since we're duplicating SLOF
code.

gtk: use setlocale() for LC_MESSAGES only
The QEMU code is not internationalized and assumes that it runs under
the C locale, but if we use the GTK+ UI we'll end up importing the
locale settings from the environment. This can break things, such as
the JSON generator and iotest 120 in locales that use a decimal comma.
We do however have translations for a few simple strings for the GTK+
menu items, so in order to run QEMU using the C locale, and yet have a
translated UI let's use setlocale() for LC_MESSAGES only.

ide: fix ATAPI command permissions
We're a little too lenient with what we'll let an ATAPI drive handle.
Clamp down on the IDE command execution table to remove CD_OK permissions
from commands that are not and have never been ATAPI commands.
For ATAPI command validity, please see:
- ATA4 Section 6.5 ("PACKET Command feature set")
- ATA8/ACS Section 4.3 ("The PACKET feature set")
- ACS3 Section 4.3 ("The PACKET feature set")
ACS3 has a historical command validity table in Table B.4
("Historical Command Assignments") that can be referenced to find when
a command was introduced, deprecated, obsoleted, etc.
The only reference for ATAPI command validity is by checking that
version's PACKET feature set section.
ATAPI was introduced by T13 into ATA4, all commands retired prior to ATA4
therefore are assumed to have never been ATAPI commands.
Mandatory commands, as listed in ATA8-ACS3, are:
- DEVICE RESET
- EXECUTE DEVICE DIAGNOSTIC
- IDENTIFY DEVICE
- IDENTIFY PACKET DEVICE
- NOP
- PACKET
- READ SECTOR(S)
- SET FEATURES
Optional commands as listed in ATA8-ACS3, are:
- FLUSH CACHE
- READ LOG DMA EXT
- READ LOG EXT
- WRITE LOG DMA EXT
- WRITE LOG EXT
All other commands are illegal to send to an ATAPI device and should
be rejected by the device.
CD_OK removal justifications:
0x06 WIN_DSM Defined in ACS2. Not valid for ATAPI.
0x21 WIN_READ_ONCE Retired in ATA5. Not ATAPI in ATA4.
0x94 WIN_STANDBYNOW2 Retired in ATA4. Did not coexist with ATAPI.
0x95 WIN_IDLEIMMEDIATE2 Retired in ATA4. Did not coexist with ATAPI.
0x96 WIN_STANDBY2 Retired in ATA4. Did not coexist with ATAPI.
0x97 WIN_SETIDLE2 Retired in ATA4. Did not coexist with ATAPI.
0x98 WIN_CHECKPOWERMODE2 Retired in ATA4. Did not coexist with ATAPI.
0x99 WIN_SLEEPNOW2 Retired in ATA4. Did not coexist with ATAPI.
0xE0 WIN_STANDBYNOW1 Not part of ATAPI in ATA4, ACS or ACS3.
0xE1 WIN_IDLEIMMDIATE Not part of ATAPI in ATA4, ACS or ACS3.
0xE2 WIN_STANDBY Not part of ATAPI in ATA4, ACS or ACS3.
0xE3 WIN_SETIDLE1 Not part of ATAPI in ATA4, ACS or ACS3.
0xE4 WIN_CHECKPOWERMODE1 Not part of ATAPI in ATA4, ACS or ACS3.
0xE5 WIN_SLEEPNOW1 Not part of ATAPI in ATA4, ACS or ACS3.
0xF8 WIN_READ_NATIVE_MAX Obsoleted in ACS3. Not ATAPI in ATA4 or ACS.
This patch fixes a divide by zero fault that can be caused by sending
the WIN_READ_NATIVE_MAX command to an ATAPI drive, which causes it to
attempt to use zeroed CHS values to perform sector arithmetic.

target-arm: Share all common TCG temporaries
This is a bug fix for aarch64. At present, we have branches using
the 32-bit (translate.c) versions of cpu_[NZCV]F, but we set the flags
using the 64-bit (translate-a64.c) versions of cpu_[NZCV]F. From
the view of the TCG code generator, these are unrelated variables.
The bug is hard to see because we currently only read these variables
from branches, and upon reaching a branch TCG will first spill live
variables and then reload the arguments of the branch. Since the
32-bit versions were never live until reaching the branch, we'd re-read
the data that had just been spilled from the 64-bit versions.
There is currently no such problem with the cpu_exclusive_* variables,
but there's no point in tempting fate.

cpus.c: qemu_mutex_lock_iothread fix race condition at cpu thread init
When QEMU starts the RCU thread executes qemu_mutex_lock_thread
causing error "qemu:qemu_cpu_kick_thread: No such process" and exits.
This isn't occur frequently but in glibc the thread id can exist and
this not guarantee that the thread is on active/running state. If is
inserted a sleep(1) after newthread assignment [1] the issue appears.
So not make assumption that thread exist if first_cpu->thread is set
then change the validation of cpu to created that is set into cpu
threads (kvm, tcg, dummy).

rtl8139: Fix receive buffer overflow check
rtl8139_do_receive() tries to check for the overflow condition
by making sure that packet_size + 8 does not exceed the
available buffer space. The issue here is that RxBuffAddr,
used to calculate available buffer space, is aligned to a
a 4 byte boundry after every update. So it is possible that
every packet ends up being slightly padded when written
to the receive buffer. This padding is not taken into
account when checking for overflow and we may end up missing
the overflow condition can causing buffer overwrite.
This patch takes alignment into consideration when
checking for overflow condition.

s390x/css: start with cleared cstat/dstat
When executing the start function, we should start with a clear state
regarding subchannel and device status; it is easy to forget updating one
of them after the ccw has been processed.
Note that we don't need to care about resetting the various control
fields: They are cleared by tsch(), and if they were still pending,
we wouldn't be able to execute the start function in the first
place.
Also note that we don't want to clear cstat/dstat if a suspended
subchannel is resumed.
This fixes a bug where we would continue to present channel-program
check in cstat even though later ccw requests for the subchannel
finished without error (i.e. cstat should be 0).

The code to flush the DBDMA channel was effectively duplicated in
dbdma_control_write(), except for the fact that the copy executed outside of a
RUN bit transition was broken by not clearing the FLUSH bit once the flush was
complete.
Newer PPC Linux kernels would timeout waiting for the FLUSH bit to clear again
after submitting a FLUSH command. Fix this by always clearing the FLUSH bit
once the channel flush is complete and removing the repeated code.

mirror: Fix coroutine reentrance
This fixes a regression introduced by commit dcfb3beb ("mirror: Do zero
write on target if sectors not allocated"), which was reported to cause
aborts with the message "Co-routine re-entered recursively".
The cause for this bug is the following code in mirror_iteration_done():
if (s->common.busy) {
qemu_coroutine_enter(s->common.co, NULL);
}
This has always been ugly because - unlike most places that reenter - it
doesn't have a specific yield that it pairs with, but is more
uncontrolled. What we really mean here is "reenter the coroutine if
it's in one of the four explicit yields in mirror.c".
This used to be equivalent with s->common.busy because neither
mirror_run() nor mirror_iteration() call any function that could yield.
However since commit dcfb3beb this doesn't hold true any more:
bdrv_get_block_status_above() can yield.
So what happens is that bdrv_get_block_status_above() wants to take a
lock that is already held, so it adds itself to the queue of waiting
coroutines and yields. Instead of being woken up by the unlock function,
however, it gets woken up by mirror_iteration_done(), which is obviously
wrong.
In most cases the code actually happens to cope fairly well with such
cases, but in this specific case, the unlock must already have scheduled
the coroutine for wakeup when mirror_iteration_done() reentered it. And
then the coroutine happened to process the scheduled restarts and tried
to reenter itself recursively.
This patch fixes the problem by pairing the reenter in
mirror_iteration_done() with specific yields instead of abusing
s->common.busy.

scsi-disk: Fix assertion failure on WRITE SAME
The last portion of an unaligned WRITE SAME command could fail the
assertion in bdrv_aligned_pwritev:
assert(!qiov || bytes == qiov->size);
Because we updated data->iov.iov_len right above this if block, but
data->qiov still has the old size.
Reinitialize the qiov to make them equal and keep block layer happy.

bytes to process network packets. While receiving packets
via ne2000_receive() routine, a local 'index' variable

vnc: fix memory corruption (CVE-2015-5225)
The _cmp_bytes variable added by commit "bea60dd ui/vnc: fix potential
memory corruption issues" can become negative. Result is (possibly
exploitable) memory corruption. Reason for that is it uses the stride
instead of bytes per scanline to apply limits.
For the server surface is is actually fine. vnc creates that itself,
there is never any padding and thus scanline length always equals stride.
For the guest surface scanline length and stride are typically identical
too, but it doesn't has to be that way. So add and use a new variable
(guest_ll) for the guest scanline length. Also rename min_stride to
line_bytes to make more clear what it actually is. Finally sprinkle
in an assert() to make sure we never use a negative _cmp_bytes again.

block: don't register quorum driver if SHA256 support is unavailable
Commit 488981a4 [block: convert quorum blockdrv to use crypto APIs]
broke qemu-iotest 041 on hosts with GnuTLS < 2.10.0. It converted a
compile-time check to a run-time check at device open time. The result
is that we now advertise a feature (the quorum block driver) that will
never work (on those hosts). There's no way (short of parsing
human-readable error messages) for qemu-iotests or any other API
consumer to recognise that the quorum block driver isn't _actually_
available and shouldn't be used or tested.
Move the run-time check to bdrv_quorum_init() to avoid registering the
quorum block driver if we know it cannot work. This way API consumers
can recognise it's unavailable.

>From the global state section, we don't need runstate with Xen. Right now,
the way the Xen toolstack knows when QEMU is ready is when QEMU reach
"running" runstate.
The configuration section and the section footers are not going to be
present in previous version of QEMU with xenfv machine, so we skip them.
The Xen toolstack libxenlight does not specify a particular version of the
'pc' machine, so migration from older version of QEMU used by Xen to newer
one would break due to missing "configuration" section and section footers.

migration: Fix global state with Xen.
When doing migration via the QMP command xen_save_devices_state, the
current runstate is not store into the global state section. Also the
current runstate is not the one we want on the receiver side.
During migration, the Xen toolstack paused QEMU before save the devices
state. Also, the toolstack expect QEMU to autostart when the migration is
finished.
So this patch store "running" as it's current runstate.

rtl8139: avoid nested ifs in IP header parsing (CVE-2015-5165)
Transmit offload needs to parse packet headers. If header fields have
unexpected values the offload processing is skipped.
The code currently uses nested ifs because there is relatively little
input validation. The next patches will add missing input validation
and a goto label is more appropriate to avoid deep if statement nesting.

tcg/mips: fix add2
The add2 code in the tcg_out_addsub2 function doesn't take into account
the case where rl == al == bl. In that case we can't compute the carry
after the addition. As it corresponds to a multiplication by 2, the
carry bit is the bit 31.
While this is a corner case, this prevents x86-64 guests to boot on a
MIPS host.

AioContext: force event loop iteration using BH
The notify_me optimization introduced in commit eabc97797310
("AioContext: fix broken ctx->dispatching optimization") skips
event_notifier_set() calls when the event loop thread is not blocked in
ppoll(2).
This optimization causes a deadlock if two aio_context_acquire() calls
race. notify_me = 0 during the race so the winning thread can enter
ppoll(2) unaware that the other thread is waiting its turn to acquire
the AioContext.
This patch forces ppoll(2) to return by scheduling a BH instead of
calling aio_notify().
The following deadlock with virtio-blk dataplane is fixed:
qemu ... -object iothread,id=iothread0 \
-drive if=none,id=drive0,file=test.img,... \
-device virtio-blk-pci,iothread=iothread0,drive=drive0
This command-line results in a hang early on without this patch.
Thanks to Paolo Bonzini <pbonzini@redhat.com> for investigating this bug
with me.

hw/net: handle flow control in mcf_fec driver receiver
The network mcf_fec driver emulated receive side method is not dealing
with network queue flow control properly.
Modify the receive side to check if we have enough space in the
descriptors to store the current packet. If not we process none of it
and return 0. When the guest frees up some buffers through its descriptors
we signal the qemu net layer to send more packets.
[Fixed coding style: 4-space indent and curly braces on if statement.

block/ssh: Avoid segfault if inet_connect doesn't set errno.
On some (but not all) systems:
$ qemu-img create -f qcow2 overlay -b ssh://xen/
Segmentation fault
It turns out this happens when inet_connect returns -1 in the
following code, but errno == 0.
s->sock = inet_connect(s->hostport, errp);
if (s->sock < 0) {
ret = -errno;
goto err;
}
In the test case above, no host called "xen" exists, so getaddrinfo fails.
On Fedora 22, getaddrinfo happens to set errno = ENOENT (although it
is *not* documented to do that), so it doesn't segfault.
On RHEL 7, errno is not set by the failing getaddrinfo, so ret =
-errno = 0, so the caller doesn't know there was an error and
continues with a half-initialized BDRVSSHState struct, and everything
goes south from there, eventually resulting in a segfault.
Fix this by setting ret to -EIO (same as block/nbd.c and
block/sheepdog.c). The real error is saved in the Error** errp
struct, so it is printed correctly:
$ ./qemu-img create -f qcow2 overlay -b ssh://xen/
qemu-img: overlay: address resolution failed for xen:22: No address associated with hostname

sheepdog: serialize requests to overwrapping area
Current sheepdog driver only serializes create requests in oid
unit. This mechanism isn't enough for handling requests to
overwrapping area spanning multiple oids, so it can result bugs like
below:
https://bugs.launchpad.net/sheepdog-project/+bug/1456421
This patch adds a new serialization mechanism for the problem. The
difference from the old one is:
1. serialize entire aiocb if their targetting areas overwrap
2. serialize all requests (read, write, and discard), not only creates
This patch also removes the old mechanism because the new one can be
an alternative.

memory: do not add a reference to the owner of aliased regions
Very often the owner of the aliased region is the same as the owner of the alias
region itself. When this happens, the reference count can never go back to 0 and
the owner is leaked. This is for example breaking hot-unplug of virtio-pci
devices (the device cannot be plugged back again with the same id).
Another common use for alias is to transform the system I/O address space
into an MMIO regions; in this case the aliased region never dies, so there
is no problem. Otherwise the owner is always the same for aliasing
and aliased region.
I checked all calls to memory_region_init_alias introduced after commit
dfde4e6 (memory: add ref/unref calls, 2013-05-06) and they do not need the
reference in order to keep the owner of the aliased region alive.

megasas: Add write function to handle write access to PCI BAR 3
This patch fixes a QEMU SEGFAULT when a write operation is performed on
the memory region of the PCI BAR 3 (base address space).
When a writeb(0xe0000000) is performed the .write function is invoked to
handle the write access, however, since the .write is not initialised,
the call to 0, causes QEMU to SEGFAULT.

main-loop: fix qemu_notify_event for aio_notify optimization
aio_notify can be optimized away, and in fact almost always will. However,
qemu_notify_event is used in places where this is incorrect---most notably,
when handling SIGTERM. When aio_notify is optimized away, it is possible that
QEMU enters a blocking ppoll immediately afterwards and stays there, without
reaching main_loop_should_exit().
Fix this by using a bottom half. The bottom half can be optimized too, but
scheduling it is enough for the ppoll not to block. The hang is thus avoided.

Date: Fri Jul 24 10:26:51 2015 -0400
block: vpc - prevent overflow if max_table_entries >= 0x40000000
When we allocate the pagetable based on max_table_entries, we multiply
the max table entry value by 4 to accomodate a table of 32-bit integers.
However, max_table_entries is a uint32_t, and the VPC driver accepts
ranges for that entry over 0x40000000. So during this allocation:
s->pagetable = qemu_try_blockalign(bs->file, s->max_table_entries * 4);
The size arg overflows, allocating significantly less memory than
expected.
Since qemu_try_blockalign() size argument is size_t, cast the
multiplication correctly to prevent overflow.
The value of "max_table_entries * 4" is used elsewhere in the code as
well, so store the correct value for use in all those cases.
We also check the Max Tables Entries value, to make sure that it is <
SIZE_MAX / 4, so we know the pagetable size will fit in size_t.

axienet: Flush queued packets when rx is done
eth_can_rx checks s->rxsize and returns false if it is non-zero. Because
of the .can_receive semantics change, this will make the incoming queue
disabled by peer, until it is explicitly flushed. So we should flush it
when s->rxsize is becoming zero.
Squash eth_can_rx semantics into etx_rx and drop .can_receive()
callback, also add flush when rx buffer becomes available again after a
packet gets queued.
The other conditions, "!axienet_rx_resetting(s) &&
axienet_rx_enabled(s)" are OK because enet_write already calls
qemu_flush_queued_packets when the register bits are changed.

stellaris_enet: Flush queued packets when read done
If s->np reaches 31, the queue will be disabled by peer when it sees
stellaris_enet_can_receive() returns false, until we explicitly flushes
it which notifies the peer. Do this when guest is done reading all
existing data.
Move the semantics to stellaris_enet_receive, by returning 0 when the

stellaris_enet_read, flush and restart the queue when guest has done

hw/net: add simple phy support to mcf_fec driver
The Linux fec driver needs at least basic phy support to probe and work.
The current qemu mcf_fec emulation has no support for the reading or
writing of the MDIO lines to access an attached phy.
This code adds a very simple set of register results for a fixed phy
setup - very similar to that used on an m5208evb board. This is enough
to probe and identify an emulated attached phy.

later discovered & fixed by commit bd09594, thanks to the

detect this directly in the crypto unit tests. Also remove

ide: Check array bounds before writing to io_buffer (CVE-2015-5154)
If the end_transfer_func of a command is called because enough data has
been read or written for the current PIO transfer, and it fails to
correctly call the command completion functions, the DRQ bit in the
status register and s->end_transfer_func may remain set. This allows the
guest to access further bytes in s->io_buffer beyond s->data_end, and
eventually overflowing the io_buffer.
One case where this currently happens is emulation of the ATAPI command
START STOP UNIT.
This patch fixes the problem by adding explicit array bounds checks
before accessing the buffer instead of relying on end_transfer_func to
function correctly.

framebuffer: set DIRTY_MEMORY_VGA on RAM that is used for the framebuffer
The MemoryRegionSection contains enough information to access the
RAM region underlying the framebuffer, and can be cached inside the
display device.
By doing this, the new framebuffer_update_memory_section function can
enable dirty memory logging on the relevant RAM region. The function
must be called whenever the stride or base of the framebuffer changes;
a simple way to cover these cases is to call it on every full frame

memory: count number of active VGA logging clients
For a board that has multiple framebuffer devices, both of them
might want to use DIRTY_MEMORY_VGA on the same memory region.
The lack of reference counting in memory_region_set_log makes
this very awkward to implement.

scsi: Handle no media case for scsi_get_configuration
Currently, scsi_get_configuration always returns a current
profile (DVD or CD), even when there is actually no media present.
By comparison, ide/atapi uses a default profile of 0 (MMC_PROFILE_NONE)
for this case and checks for tray_open, so let's do the same for scsi.
This fixes a problem I'm seeing with Fedora 22 guests where systemd
cdrom_id fails to unmount after a QEMU-initiated eject against a
scsi cdrom device because it believes the media is still present
(but unreadable).

This is a guest-triggerable buffer overflow present in QEMU 2.2.0

Luckily, the massive overflow means that QEMU will just SIGSEGV,

qemu-char: Fix missed data on unix socket
Commit 812c1057 introduced HUP detection on unix and tcp sockets prior
to a read in tcp_chr_read. This unfortunately broke CloudStack 4.2
which relied on the old behaviour where data on a socket was readable
even if a HUP was present.
A working solution is to properly check the return values from recv,
handling a closed socket once there is no more data to read.
Also enable polling for G_IO_NVAL to ensure the callback is called
for all possible events as these should now be possible to handle
with the improved error detection.

vfio/pci: Fix RTL8168 NIC quirks
The RTL8168 quirk correctly describes using bit 31 as a signal to
mark a latch/completion, but the code mistakenly uses bit 28. This
causes the Realtek driver to spin on this register for quite a while,
20k cycles on Windows 7 v7.092 driver. Then it gets frustrated and
tries to set the bit itself and spins for another 20k cycles. For
some this still results in a working driver, for others not. About
the only thing the code really does in its current form is protect
the guest from sneaking in writes to the real hardware MSI-X table.
The fix is obviously to use bit 31 as we document that we should.
The other problem doesn't seem to affect current drivers as nobody
seems to use these window registers for writes to the MSI-X table, but
we need to use the stored data when a write is triggered, not the
value of the current write, which only provides the offset.
Note that only the Windows drivers from Realtek seem to use these
registers, the Microsoft drivers provided with Windows 8.1 do not
access them, nor do Linux in-kernel drivers.

AioContext: optimize clearing the EventNotifier
It is pretty rare for aio_notify to actually set the EventNotifier. It
can happen with worker threads such as thread-pool.c's, but otherwise it
should never be set thanks to the ctx->notify_me optimization. The
previous patch, unfortunately, added an unconditional call to
event_notifier_test_and_clear; now add a userspace fast path that
avoids the call.
Note that it is not possible to do the same with event_notifier_set;
it would break, as proved (again) by the included formal model.
This patch survived over 3000 reboots on aarch64 KVM.

AioContext: fix broken placement of event_notifier_test_and_clear
event_notifier_test_and_clear must be called before processing events.
Otherwise, an aio_poll could "eat" the notification before the main
I/O thread invokes ppoll(). The main I/O thread then never wakes up.
This is an example of what could happen:
i/o thread vcpu thread worker thread
---------------------------------------------------------------------
lock_iothread
notify_me = 1
...
unlock_iothread
bh->scheduled = 1
event_notifier_set
lock_iothread
notify_me = 3
ppoll
notify_me = 1
aio_dispatch
aio_bh_poll
thread_pool_completion_bh
bh->scheduled = 1
event_notifier_set
node->io_read(node->opaque)
event_notifier_test_and_clear
ppoll
*** hang ***
"Tracing" with qemu_clock_get_ns shows pretty much the same behavior as
in the previous bug, so there are no new tricks here---just stare more
at the code until it is apparent.
One could also use a formal model, of course. The included one shows
this with three processes: notifier corresponds to a QEMU thread pool
worker, temporary_waiter to a VCPU thread that invokes aio_poll(),
waiter to the main I/O thread. I would be happy to say that the
formal model found the bug for me, but actually I wrote it after the
fact.
This patch is a bit of a big hammer. The next one optimizes it,
with help (this time for real rather than a posteriori :)) from
another, similar formal model.

This patch rewrites the ctx->dispatching optimization, which was the cause
of some mysterious hangs that could be reproduced on aarch64 KVM only.
The hangs were indirectly caused by aio_poll() and in particular by
flash memory updates's call to blk_write(), which invokes aio_poll().
Fun stuff: they had an extremely short race window, so much that
adding all kind of tracing to either the kernel or QEMU made it
go away (a single printf made it half as reproducible).
On the plus side, the failure mode (a hang until the next keypress)
made it very easy to examine the state of the process with a debugger.
And there was a very nice reproducer from Laszlo, which failed pretty
often (more than half of the time) on any version of QEMU with a non-debug
kernel; it also failed fast, while still in the firmware. So, it could
have been worse.
For some unknown reason they happened only with virtio-scsi, but
that's not important. It's more interesting that they disappeared with
io=native, making thread-pool.c a likely suspect for where the bug arose.
thread-pool.c is also one of the few places which use bottom halves
across threads, by the way.
I hope that no other similar bugs exist, but just in case :) I am
going to describe how the successful debugging went... Since the
likely culprit was the ctx->dispatching optimization, which mostly
affects bottom halves, the first observation was that there are two
qemu_bh_schedule() invocations in the thread pool: the one in the aio
worker and the one in thread_pool_completion_bh. The latter always
causes the optimization to trigger, the former may or may not. In
order to restrict the possibilities, I introduced new functions
qemu_bh_schedule_slow() and qemu_bh_schedule_fast():
/* qemu_bh_schedule_slow: */
ctx = bh->ctx;
bh->idle = 0;
if (atomic_xchg(&bh->scheduled, 1) == 0) {
event_notifier_set(&ctx->notifier);
}
/* qemu_bh_schedule_fast: */
ctx = bh->ctx;
bh->idle = 0;
assert(ctx->dispatching);
atomic_xchg(&bh->scheduled, 1);
Notice how the atomic_xchg is still in qemu_bh_schedule_slow(). This
was already debated a few months ago, so I assumed it to be correct.
In retrospect this was a very good idea, as you'll see later.
Changing thread_pool_completion_bh() to qemu_bh_schedule_fast() didn't
trigger the assertion (as expected). Changing the worker's invocation
to qemu_bh_schedule_slow() didn't hide the bug (another assumption
which luckily held). This already limited heavily the amount of
interaction between the threads, hinting that the problematic events
must have triggered around thread_pool_completion_bh().
As mentioned early, invoking a debugger to examine the state of a
hung process was pretty easy; the iothread was always waiting on a
poll(..., -1) system call. Infinite timeouts are much rarer on x86,
and this could be the reason why the bug was never observed there.
With the buggy sequence more or less resolved to an interaction between
thread_pool_completion_bh() and poll(..., -1), my "tracing" strategy was
to just add a few qemu_clock_get_ns(QEMU_CLOCK_REALTIME) calls, hoping
that the ordering of aio_ctx_prepare(), aio_ctx_dispatch, poll() and
qemu_bh_schedule_fast() would provide some hint. The output was:
(gdb) p last_prepare
$3 = 103885451
(gdb) p last_dispatch
$4 = 103876492
(gdb) p last_poll
$5 = 115909333
(gdb) p last_schedule
$6 = 115925212
Notice how the last call to qemu_poll_ns() came after aio_ctx_dispatch().
This makes little sense unless there is an aio_poll() call involved,
and indeed with a slightly different instrumentation you can see that
there is one:
(gdb) p last_prepare
$3 = 107569679
(gdb) p last_dispatch
$4 = 107561600
(gdb) p last_aio_poll
$5 = 110671400
(gdb) p last_schedule
$6 = 110698917
So the scenario becomes clearer:
iothread VCPU thread
--------------------------------------------------------------------------
aio_ctx_prepare
aio_ctx_check
qemu_poll_ns(timeout=-1)
aio_poll
aio_dispatch
thread_pool_completion_bh
qemu_bh_schedule()
At this point bh->scheduled = 1 and the iothread has not been woken up.
The solution must be close, but this alone should not be a problem,
because the bottom half is only rescheduled to account for rare situations
(see commit 3c80ca1, thread-pool: avoid deadlock in nested aio_poll()
calls, 2014-07-15).
Introducing a third thread---a thread pool worker thread, which
also does qemu_bh_schedule()---does bring out the problematic case.
The third thread must be awakened *after* the callback is complete and
thread_pool_completion_bh has redone the whole loop, explaining the
short race window. And then this is what happens:
thread pool worker
--------------------------------------------------------------------------
<I/O completes>
qemu_bh_schedule()
Tada, bh->scheduled is already 1, so qemu_bh_schedule() does nothing
and the iothread is never woken up. This is where the bh->scheduled
optimization comes into play---it is correct, but removing it would
have masked the bug.
So, what is the bug?
Well, the question asked by the ctx->dispatching optimization ("is any
active aio_poll dispatching?") was wrong. The right question to ask
instead is "is any active aio_poll *not* dispatching", i.e. in the prepare
or poll phases? In that case, the aio_poll is sleeping or might go to
sleep anytime soon, and the EventNotifier must be invoked to wake
it up.
In any other case (including if there is *no* active aio_poll at all!)
we can just wait for the next prepare phase to pick up the event (e.g. a
bottom half); the prepare phase will avoid the blocking and service the
bottom half.
Expressing the invariant with a logic formula, the broken one looked like:
!(exists(thread): in_dispatching(thread)) => !optimize
or equivalently:
!(exists(thread):
in_aio_poll(thread) && in_dispatching(thread)) => !optimize
In the correct one, the negation is in a slightly different place:
(exists(thread):
in_aio_poll(thread) && !in_dispatching(thread)) => !optimize
or equivalently:
(exists(thread): in_prepare_or_poll(thread)) => !optimize
Even if the difference boils down to moving an exclamation mark :)
the implementation is quite different. However, I think the new
one is simpler to understand.
In the old implementation, the "exists" was implemented with a boolean
value. This didn't really support well the case of multiple concurrent
event loops, but I thought that this was okay: aio_poll holds the
AioContext lock so there cannot be concurrent aio_poll invocations, and
I was just considering nested event loops. However, aio_poll _could_
indeed be concurrent with the GSource. This is why I came up with the
wrong invariant.
In the new implementation, "exists" is computed simply by counting how many
threads are in the prepare or poll phases. There are some interesting
points to consider, but the gist of the idea remains:
1) AioContext can be used through GSource as well; as mentioned in the
patch, bit 0 of the counter is reserved for the GSource.
2) the counter need not be updated for a non-blocking aio_poll, because
it won't sleep forever anyway. This is just a matter of checking
the "blocking" variable. This requires some changes to the win32
implementation, but is otherwise not too complicated.
3) as mentioned above, the new implementation will not call aio_notify
when there is *no* active aio_poll at all. The tests have to be
adjusted for this change. The calls to aio_notify in async.c are fine;
they only want to kick aio_poll out of a blocking wait, but need not
do anything if aio_poll is not running.
4) nested aio_poll: these just work with the new implementation; when
a nested event loop is invoked, the outer event loop is never in the
prepare or poll phases. The outer event loop thus has already decremented
the counter.

aio-win32: reorganize polling loop
Preparatory bugfixes and tweaks to the loop before the next patch:
- disable dispatch optimization during aio_prepare. This fixes a bug.
- do not modify "blocking" until after the first WaitForMultipleObjects
call. This is needed in the next patch.
- change the loop to do...while. This makes it obvious that the loop
is always entered at least once. In the next patch this is important
because the first iteration undoes the ctx->notify_me increment that
happened before entering the loop.

In these tests, the purpose of the initial calls to aio_poll and
g_main_context_iteration is simply to put the AioContext in a
known state; the return value of the function does not really
matter. The next patch will change those return values; change
the assertions to a while loop which expresses the intention

net/vmxnet3: Fix RX TCP/UDP checksum on partially summed packets
Convert partially summed packets to be fully checksummed.
In case csum offloaded packet, vmxnet3 implementation always passes an
RxCompDesc with the "Checksum calculated and found correct" notification
to the OS. This emulates the observed ESXi behavior.
Therefore, if packet has the NEEDS_CSUM bit set, we must calculate and
place a fully computed checksum into the tcp/udp header. Otherwise, the
OS driver will receive a checksum-correct indication but with the actual
tcp/udp checksum field having just the pseudo header csum value.
If host OS performs forwarding, it will forward an incorrectly
checksummed packet.

qtest/ide: add another short PRDT test flavor
The existing short PRDT test case does not transfer any data because the
first PRD is less than 1 sector.
This patch adds another short PRDT test case where the first sector can
be read but the PRDT is still smaller than the requested number of
sectors. This exercises a different code path in ide_dma_cb().

timer: rename NSEC_PER_SEC due to Mac OS X header clash
Commit e0cf11f31c24cfb17f44ed46c254d84c78e7f6e9 ("timer: Use a single
definition of NSEC_PER_SEC for the whole codebase") renamed
NANOSECONDS_PER_SECOND to NSEC_PER_SEC.
On Mac OS X there is a <dispatch/time.h> system header which also
defines NSEC_PER_SEC. This causes compiler warnings.
Let's use the old name instead. It's longer but it doesn't clash.

virtio-net: Flush incoming queues when DRIVER_OK is being set
This patch fixes network hang after "stop" then "cont", while network
packets keep arriving.
Tested both manually (tap, host pinging guest) and with Jason's qtest
series (plus his "[PATCH 2.4] socket: pass correct size in
net_socket_send()" fix).
As virtio_net_set_status is called when guest driver is setting status
byte and when vm state is changing, it is a good opportunity to flush
queued packets.
This is necessary because during vm stop the backend (e.g. tap) would
stop rx processing after .can_receive returns false, until the queue is
explicitly flushed or purged.
The other interesting condition in .can_receive, virtio_queue_ready(),
is handled by virtio_net_handle_rx() when guest kicks; the 3rd condition
is invalid queue index which doesn't need flushing.

("virtio-net: byteswap virtio-net header") breaks any layout by
requiring out_sg[0].iov_len >= n->guest_hdr_len. Fixing this by
copying header to temporary buffer if swap is needed, and then use

crypto: avoid undefined behavior in nettle calls
Calling a function pointer that was cast from an incompatible function
results in undefined behavior. 'void *' isn't compatible with 'struct
XXX *', so we can't cast to nettle_cipher_func, but have to provide a
wrapper. (Conversion from 'void *' to 'struct XXX *' might require
computation, which won't be done if we drop argument's true type, and
pointers can have different sizes so passing arguments on stack would
bug.)
Having two different prototypes based on nettle version doesn't make
this solution any nicer.

memory: fix refcount leak in memory_region_present
memory_region_present() leaks a reference to a MemoryRegion in the
case "mr == container". While fixing it, avoid reference counting
altogether for memory_region_present(), by using RCU only.
The return value could in principle be already invalid immediately
after memory_region_present returns, but presumably the caller knows
that and it's using memory_region_present to probe for devices that
are unpluggable, or something like that. The RCU critical section
is needed anyway, because it protects as->current_map.

qxl: allow to specify head limit to qxl driver
This patch allow to limit number of heads using qxl driver. By default
qxl driver is not limited on any kind on head use so can decide to use
as much heads.
libvirt has this as a video card parameter (actually set to 1 but not
used). This parameter will allow to limit setting a use can do (which
could be confusing).

target-i386: emulate CPUID level of real hardware
W10 insider has a bug where it ignores CPUID level and interprets
CPUID.(EAX=07H, ECX=0H) incorrectly, because CPUID in fact returned
CPUID.(EAX=04H, ECX=0H); this resulted in execution of unsupported
instructions.
While it's a Windows bug, there is no reason to emulate incorrect level.
I used http://instlatx64.atw.hu/ as a source of CPUID and checked that
it matches Penryn Xeon X5472, Westmere Xeon W3520, SandyBridge i5-2540M,
and Haswell i5-4670T.
kvm64 and qemu64 were bumped to 0xD to allow all available features for
them (and to avoid the same Windows bug).

hw/arm/boot: Increase fdt alignment
The Linux kernel on aarch64 creates a page table entry at early bootup
that spans the 2MB range on memory spanning the fdt start address:
[ ALIGN_DOWN(fdt, 2MB) ... ALIGN_DOWN(fdt, 2MB) + 2MB ]
This means that when our current 4k alignment happens to fall at the end
of the aligned region, Linux tries to access memory that is not mapped.
The easy fix is to instead increase the alignment to 2MB, making Linux's
logic always succeed.
We leave the existing 4k alignment for 32bit kernels to not cause any
regressions due to space constraints.

target-arm: Fix broken SCTLR_EL3 reset
The SCTLR_EL3 cpreg definition was implicitly resetting the
register state to 0, which is both wrong and clashes with
the reset done via the SCTLR definition (since sctlr[3]
is unioned with sctlr_s). This went unnoticed until recently,
when an unrelated change (commit a903c449b41f105aa) happened to
perturb the order of enumeration through the cpregs hashtable for
reset such that the erroneous reset happened after the correct one
rather than before it. Fix this by marking SCTLR_EL3 as an alias,
so its reset is left up to the AArch32 view.

target-mips: fix page fault address for LWL/LWR/LDL/LDR
When a LWL, LWR, LDL or LDR instruction triggers a page fault, QEMU
currently reports the aligned address in CP0 BadVAddr, while the Windows
NT kernel expects the unaligned address.
This patch adds a byte access with the unaligned address at the
beginning of the LWL/LWR/LDL/LDR instructions to possibly trigger a page
fault and fill the QEMU TLB.

linux-user: Fix MIPS N64 trap and break instruction bug
For the MIPS N64 ABI when QEMU reads the break/trap instruction so that
it can inspect the break/trap code it reads 8 rather than 4 bytes
which means it finds the code field from the instruction after the
break/trap instruction. This then causes the break/trap handling
code to fail because it does not understand the code number.
The fix forces QEMU to always read 4 bytes of instruction data rather
than deciding how much to read based on the ABI.

migration: We also want to store the global state for savevm
Commit df4b1024526cae3479da3492d6371fd4a7324a03 introduced global_state
section. But it only filled the state while doing migration. While
doing a savevm, we stored an empty string as state. So when we did a
loadvm, it complained that state was invalid.

Author: Richard W.M. Jones <rjones@redhat.com>

block/curl: Don't lose original error when a connection fails.
Currently if qemu is connected to a curl source (eg. web server), and
the web server fails / times out / dies, you always see a bogus EIO
"Input/output error".
For example, choose a large file located on any local webserver which
you control:
$ qemu-img convert -p http://example.com/large.iso /tmp/test
Once it starts copying the file, stop the webserver and you will see
qemu-img fail with:
qemu-img: error while reading sector 61440: Input/output error
This patch does two things: Firstly print the actual error from curl
so it doesn't get lost. Secondly, change EIO to EPROTO. EPROTO is a
POSIX.1 compatible errno which more accurately reflects that there was
a protocol error, rather than some kind of hardware failure.
After this patch is applied, the error changes to:
$ qemu-img convert -p http://example.com/large.iso /tmp/test
qemu-img: curl: transfer closed with 469989 bytes remaining to read
qemu-img: error while reading sector 16384: Protocol error

Draining is not necessary, I/O can happen as soon as the
commit coroutine yields. Draining can be necessary before
reopening the file for read/write, or while modifying the
backing file chain, but that is done separately in
bdrv_reopen_multiple or bdrv_close; this particular
bdrv_drain_all does nothing for that.

watchdog/diag288: correctly register for system reset requests
The diag288 watchdog is no sysbus device, therefore it doesn't get
triggered on resets automatically using dc->reset.
Let's register the reset handler manually, so we get correctly notified
again when a system reset was requested. Also reset the watchdog on
subsystem resets that don't trigger a full system reset.

rbd: make qemu's cache setting override any ceph setting
To be safe, when cache=none is used ceph settings should not be able
to override it to turn on caching. This was previously possible with
rbd_cache=true in the rbd device configuration or a ceph configuration
file. Similarly, rbd settings could have turned off caching when qemu
requested it, although this would just be a performance problem.
Fix this by changing rbd's cache setting to match qemu after all other
ceph settings have been applied.

block: Fix backing file child when modifying graph
This patch moves bdrv_attach_child() from the individual places that add
a backing file to a BDS to bdrv_set_backing_hd(), which is called by all
of them. It also adds bdrv_detach_child() there.
For normal operation (starting with one backing file chain and not
changing it until the topmost image is closed) and live snapshots, this
constitutes no change in behaviour.
For all other cases, this is a fix for the bug that the old backing file
was still referenced as a child, and the new one wasn't referenced.

It is the same as bdrv_open_image(), except that it doesn't only return

As the BdrvChild object already contains a BlockDriverState pointer (and
this is supposed to become the only pointer so that bdrv_append() and
friends can just change a single pointer in BdrvChild), the pbs
parameter is removed for bdrv_open_child().

commit fddd179ab962f6f78a8493742e1068d6a620e059,
"pc: Convert *_MACHINE_OPTIONS macros into functions"
broke the chaining of *_machine_options() functions on
pc-i440fx-2.3, at:
-#define PC_I440FX_2_3_MACHINE_OPTIONS \
- PC_I440FX_2_4_MACHINE_OPTIONS, \
- .alias = NULL, \
- .is_default = 0
+static void pc_i440fx_2_3_machine_options(QEMUMachine *m)
+{
+ pc_i440fx_machine_options(m);
+ m->alias = NULL;
+ m->is_default = 0;
+}
I have replaced PC_I440FX_2_4_MACHINE_OPTIONS with a
pc_i440fx_machine_options() call, instead of calling
pc_i440fx_2_4_machine_options(). This broke the setting of default_machine_opts
and default_display on pc-i440fx-{2.0,2,1,2.2,2.3}.
Fix this by making pc_i440fx_2_3_machine_options() reuse
pc_i440fx_2_4_machine_options().

cc1: all warnings being treated as errors
The underlying cause of this is an include loop:
bfd.h -> qemu-common.h -> target-arm/cpu.h -> target-arm/cpu-qom.h
-> qom/cpu.h -> bfd.h
which means that if bfd.h is included first then qom/cpu.h doesn't
get the definition of the disassemble_info type that it wanted.
The easiest fix for this is to include qemu-common.h from tci.c
before including disas/bfd.h.

disas: cris: Fix 0 buffer length case
Cris has the complication of variable length instructions and has
a check in place to clamp memory reads in case the disas request
doesn't have enough bytes for the instruction being disas'd. This
breaks down in the case where disassembling for the monitor where
the buffer length is defaulted to 0.
The buffer length should never be zero for a regular target_disas,
so we can safely assume the 0 case is for the monitor in which case
consider the buffer length to be the max for cris instructions.

disas: arm: QOMify target specific disas setup
Move the target_disas() ARM specifics to the QOM disas_set_info hook
and delete the ARM specific code in disas.c.
This has the extra advantage of the more fully featured target_disas()

Date: Tue Jun 23 19:31:13 2015 -0700
cpu: Convert cpu_index into a bitmap
Currently CPUState::cpu_index is monotonically increasing and a newly
created CPU always gets the next higher index. The next available
index is calculated by counting the existing number of CPUs. This is
fine as long as we only add CPUs, but there are architectures which
are starting to support CPU removal, too. For an architecture like PowerPC
which derives its CPU identifier (device tree ID) from cpu_index, the
existing logic of generating cpu_index values causes problems.
With the currently proposed method of handling vCPU removal by parking
the vCPU fd in QEMU
(Ref: http://lists.gnu.org/archive/html/qemu-devel/2015-02/msg02604.html),
generating cpu_index this way will not work for PowerPC.
This patch changes the way cpu_index is handed out by maintaining
a bit map of the CPUs that tracks both addition and removal of CPUs.
The CPU bitmap allocation logic is part of cpu_exec_init(), which is
called by instance_init routines of various CPU targets. Newly added
cpu_exec_exit() API handles the deallocation part and this routine is
called from generic CPU instance_finalize.
Note: This new CPU enumeration is for !CONFIG_USER_ONLY only.
CONFIG_USER_ONLY continues to have the old enumeration logic.

tcg/mips: Fix build error from merged memop+mmu_idx parameter
Commit 3972ef6f830d ("tcg: Push merged memop+mmu_idx parameter to
softmmu routines") caused the following build errors when building TCG
for MIPS:
In file included from tcg/tcg.c:258:0:
tcg/mips/tcg-target.c In function ‘tcg_out_qemu_ld_slow_path’:
tcg/mips/tcg-target.c:1015:22: error: ‘lb’ undeclared (first use in this function)

tcg/mips/tcg-target.c:1058:22: error: ‘lb’ undeclared (first use in this function)
It looks like lb was meant to refer to the TCGLabelQemuLdst *l
parameter, so fix both references to lb to refer to just l.
Fixes: 3972ef6f830d ("tcg: Push merged memop+mmu_idx parameter to softmmu routines")

Thanks to the last patch, pc_cmos_init() doesn't need the (optional)

pc_basic_device_init() not to hand it back to pc_init1() / pc_q35_init(),
and update the latter not to carry the FDC to pc_cmos_init(). This
simplifies the code.

hw/i386/pc: reflect any FDC @ ioport 0x3f0 in the CMOS
With the pc-q35-2.4 machine type, if the user creates an ISA FDC manually:
-device isa-fdc,driveA=drive-fdc0-0-0 \
-drive file=...,if=none,id=drive-fdc0-0-0,format=raw
then the board-default FDC will be skipped, and only the explicitly
requested FDC will exist. qtree-wise, this is correct; however such an FDC
is currently not registered in the CMOS, because that code is only reached
for the board-default FDC.
The pc_cmos_init_late() one-shot reset handler -- one-shot because the
CMOS is not reprogrammed during warm reset -- should search for any ISA
FDC devices, created implicitly (by board code) or explicitly, and set the
CMOS accordingly to the ISA FDC(s) with iobase=0x3f0:
- if there is no such FDC, report both drives absent,
- if there is exactly one such FDC, report its drives in the CMOS,
- if there are more than one such FDCs, then pick one (it is not specified
which one), and print a warning about the ambiguity.

hw/i386/pc: factor out pc_cmos_init_floppy()
Extract the pc_cmos_init_floppy() function from pc_cmos_init(). The
function sets two RTC registers: floppy drive types (0x10), overwriting
the earlier value in there), and REG_EQUIPMENT_BYTE (0x14), setting bits
in the prior value.

ich9: implement strap SPKR pin logic
If the signal is sampled high, this indicates that the system is
strapped to the "No Reboot" mode (ICH9 will disable the TCO Timer system
reboot feature). The status of this strap is readable via the NO_REBOOT
bit (CC: offset 0x3410:bit 5).
The NO_REBOOT bit is set when SPKR pin on ICH9 is sampled high. This bit
may be set or cleared by software if the strap is sampled low but may
not override the strap when it indicates "No Reboot".
This patch implements the logic where hardware has ability to set SPKR
pin through a property named "noreboot" and it's sampled high by
default.

This patch adds a testcase that covers the following:
1) TCO default values
2) first and second TCO timeout
3) watch and validate ticks counter through TCO_RLD register
4) maximum supported TCO timeout (0x3ff)
5) watchdog actions (pause/reset/shutdown/none) upon second TCO
timeout
6) set and get of TCO control and status bits

qga: added GuestPCIAddress information
PCIAddress inforfation is obtained via SetupApi, which provides the
information about address, bus, etc. We look throught entire device tree
in the system and try to find device object for given volume. For this PDO
SetupDiGetDeviceRegistryProperty is called, which reads PCI configuration
for a given devicei if it is possible.
This is the most convinient way for a userspace service. The lookup is
performed for every volume available. However, this information is
not mandatory for vss-provider.
In order to use SetupApi we need to notify linker about it. We do not need
to install additional libs, so we do not make separate configuration
option to use libsetupapi.su
SetupApi gives as the same information as kernel driver
with IRP_MN_QUERY_INTERFACE.

qga: added bus type and disk location path
According to Microsoft disk location path can be obtained via
IOCTL_SCSI_GET_ADDRESS. Unfortunately this ioctl can not be used for all
devices. There are certain bus types which could be obtained with this
API. Please, refer to the following link for more details
https://technet.microsoft.com/en-us/library/ee851589(v=ws.10).aspx
Bus type could be obtained using IOCTL_STORAGE_QUERY_PROPERTY. Enum
STORAGE_BUS_TYPE describes all buses supported by OS.
Windows defines more bus types than Linux. Thus some values have been added
to GuestDiskBusType.

qga: added mountpoint and filesystem type for single volume
We should use GetVolumeXXX api to work with volumes. This will help us to
resolve the situation with volumes without drive letter, i.e. when the
volume is mounted as a folder. Such volume is called mounted folder.
This volume is a regular mounted volume from all other points of view.
The information about non mounted volume is reported as System Reserved.
This volume is not mounted and thus it is not writable.
GuestDiskAddressList API is not used because operations are performed with
volumes but no with disks. This means that spanned disk will
be counted and handled as a single volume. It is worth mentioning
that the information about every disk in the volume can be queried
via IOCTL_VOLUME_GET_VOLUME_DISK_EXTENTS.

By default, IPv4 prefixes will be derived by matching the address

In Windows Vista/2008 guests and newer, both IPv4 and IPv6 prefixes
can be retrieved from OnLinkPrefixLength. Setting --extra-cflags
in the build configuration to "-D_WIN32_WINNT=0x600"
or greater makes OnLinkPrefixLength available. Setting --extra-cflags
is not required and if not set, the default approach to get the prefix
will be taken.

qga/qmp_guest_fstrim: Return per path fstrim result
The current guest-fstrim support only returns an error if some
mountpoint was unable to be trimmed, skipping any possible additional
mountpoints. The result of the TRIM operation itself is also discarded.
This change returns a per mountpoint result of the TRIM operation. If an
error occurs on some mountpoints that error is returned and the
guest-fstrim continue with any additional mountpoints.
The returned values for errors, minimum and trimmed are dependant on the
filesystem, storage stacks and kernel version.

qga/commands-posix: Fix bug in guest-fstrim
The FITRIM ioctl updates the fstrim_range structure it receives. This
way the caller can determine how many bytes were trimmed. The
guest-fstrim logic reuses the same fstrim_range for each filesystem,
effectively limiting each filesystem to trim at most as much as the
previous was able to trim.
If a previous filesystem would have trimmed 0 bytes, than the next
filesystem would report an error 'Invalid argument' because a FITRIM
request with length 0 is not valid.
This change resets the fstrim_range structure for each filesystem.

sPAPR: Clear stale MSIx table during EEH reset
The PCI device MSIx table is cleaned out in hardware after EEH PE
reset. However, we still hold the stale MSIx entries in QEMU, which
should be cleared accordingly. Otherwise, we will run into another
(recursive) EEH error and the PCI devices contained in the PE have
to be offlined exceptionally.
The patch introduces function spapr_phb_vfio_eeh_pre_reset(), which
is called by sPAPR when asserting hot or fundamental reset, to clear
stale MSIx table for VFIO PCI devices before EEH PE reset so that
MSIx table could be restored properly after EEH PE reset.

spapr-vty: Use TYPE_ definition instead of hardcoding
There's a call to object_dynamic_cast() in spapr_vty which uses the type
name "spapr-vty" directly, instead of the usual idiom of using the #defined
TYPE_VIO_SPAPR_VTY_DEVICE. Fix it.

spapr_vty: lookup should only return valid VTY objects
If a guest passes the reg property of a valid VIO object that is not a VTY
to either H_GET_TERM_CHAR or H_PUT_TERM_CHAR, QEMU hits a dynamic cast
assertion and aborts.
PAPR+ says "Hypervisor checks the termno parameter for validity against the
Vterm IOA unit addresses assigned to the partition, else return H_Parameter."
This patch adds a type check to ensure vty_lookup() either returns a pointer
to a valid VTY object or NULL. H_GET_TERM_CHAR and H_PUT_TERM_CHAR will
now return H_PARAMETER to the guest instead of crashing.
The patch has no effect on the reg == 0 hack used to implement the RTAS call
display-character.

Each hardware instance has a platform unique location code. The OF
device tree that describes a part of a hardware entity must include

Populate ibm,loc-code.

spapr_pci: enumerate and add PCI device tree
All the PCI enumeration and device node creation was off-loaded to
SLOF. With PCI hotplug support, code needed to be added to add device
node. This creates multiple copy of the code one in SLOF and other in
hotplug code. To unify this, the patch adds the pci device node
creation in Qemu. For backward compatibility, a flag
"qemu,phb-enumerated" is added to the phb, suggesting to SLOF to not
do device node creation.

xics_kvm: Don't enable KVM_CAP_IRQ_XICS if already enabled
When supporting CPU hot removal by parking the vCPU fd and reusing
it during hotplug again, there can be cases where we try to reenable
KVM_CAP_IRQ_XICS CAP for the vCPU for which it was already enabled.
Introduce a boolean member in ICPState to track this and don't
reenable the CAP if it was already enabled earlier.
Re-enabling this CAP should ideally work, but currently it results in
kernel trying to create and associate ICP with this vCPU and that
fails since there is already an ICP associated with it. Hence this
patch is needed to work around this problem in the kernel.
This change allows CPU hot removal to work for sPAPR.

Worse, the existing code was inconsistent about where it got the ram size

and sometimes a local 'ram_size' masking the global.
This cleans up the code to consistently use machine->ram_size, eliminating

Now that we have the generic MachineState, fold sPAPREnvironment into

spapr: ensure we have at least one XICS server
XICS needs to know the upper value for cpu_index as it is used to compute
the number of servers:
smp_cpus * kvmppc_smt_threads() / smp_threads
When passing -smp cpus=1,threads=9 on a POWER8 host, we end up with:
1 * 8 / 9 = 0
... which leads to an assertion in both emulated:
Number of servers needs to be greater 0
Aborted (core dumped)
... and in-kernel XICS:
xics_kvm_realize: Assertion `icp->nr_servers' failed.
Aborted (core dumped)
With this patch, we are sure that nr_servers > 0. Passing the same bogus
-smp option then leads to:

target-ppc: fix hugepage support when using memory-backend-file
Current PPC code relies on -mem-path being used in order for
hugepage support to be detected. With the introduction of
MemoryBackendFile we can now handle this via:
-object memory-file-backend,mem-path=...,id=hugemem0 \
-numa node,id=mem0,memdev=hugemem0
Management tools like libvirt treat the 2 approaches as
interchangeable in some cases, which can lead to user-visible
regressions even for previously supported guest configurations.
Fix these by also iterating through any configured memory
backends that may be backed by hugepages.
Since the old code assumed hugepages always backed the entirety
of guest memory, play it safe an pick the minimum across the
max pages sizes for all backends, even ones that aren't backed
by hugepages.

target-i386: avoid overflow in the tsc-frequency property
The TSC frequency fits comfortably in an int when expressed in kHz,
but it may overflow when converted to Hz. In this case,
tsc-frequency returns a negative value because x86_cpuid_get_tsc_freq
does a 32-bit multiplication before assigning to int64_t.
For simplicity just make tsc_khz a 64-bit value.
Spotted by Coverity.

i386: Introduce ARAT CPU feature
ARAT signals that the APIC timer does not stop in power saving states.
As our APICs are emulated, it's fine to expose this feature to guests,
at least when asking for KVM host features or with CPU types that
include the flag. The exact model number that introduced the feature is
not known, but reports can be found that it's at least available since
Sandy Bridge.

block/raw-posix: Don't think /dev/fd/<NN> is a floppy drive.
In libguestfs we use /dev/fd/<NN> to pass pre-opened file descriptors
to qemu-img. Lately I've discovered that although this works, qemu
believes that these are floppy disk images. That in itself isn't much
of a problem, but now qemu prints a warning about host floppy
pass-thru being deprecated.
Extend the existing test so that it ignores /dev/fd/ as well as
/dev/fdset/
A simple test of this, if you are using the bash shell, is:
qemu-img info <( cat /dev/null )
without this patch:
$ qemu-img info <( cat /dev/null )
qemu-img: Host floppy pass-through is deprecated
Support for it will be removed in a future release.

migration: create new section to store global state
This includes a new section that for now just stores the current qemu state.
Right now, there are only one way to control what is the state of the
target after migration.
- If you run the target qemu with -S, it would start stopped.
- If you run the target qemu without -S, it would run just after migration finishes.
The problem here is what happens if we start the target without -S and
there happens one error during migration that puts current state as
-EIO. Migration would ends (notice that the error happend doing block
IO, network IO, i.e. nothing related with migration), and when
migration finish, we would just "continue" running on destination,
probably hanging the guest/corruption data, whatever.

destination, QEMU would hang waiting for a disconnect on the source
and wouldn't release from that hang until the destination was manually
killed.
Mark the stream as being in error, this causes the destination to die
and the source to carry on.

Sort destination RAMBlocks to be the same as the source
Use the order of incoming RAMBlocks from the source to record
an index number; that then allows us to sort the destination
local RAMBlock list to match the source.
Now that the RAMBlocks are known to be in the same order, this
simplifies the RDMA Registration step which previously tried to
match RAMBlocks based on offset (which isn't guaranteed to match).
Looking at the existing compress code, I think it was erroneously
relying on an assumption of matching ordering, which this fixes.

Translate offsets to destination address space
The 'offset' field in RDMACompress and 'current_addr' field
in RDMARegister are commented as being offsets within a particular
RAMBlock, however they appear to actually be offsets within the
ram_addr_t space.
The code currently assumes that the offsets on the source/destination
match, this change removes the need for the assumption for these
structures by translating the addresses into the ram_addr_t space of
the destination host.
Note: An alternative would be to change the fields to actually
take the data they're commented for; this would potentially be
simpler but would break stream compatibility for those cases
that currently work.

rocker: mark copy-to-cpu pkts as forwarding offloaded
For pkts copied to the CPU (to be processed by guest driver), mark the Rx
descriptor with flag "OFFLOAD_FWD" to indicate device has already forwarded
pkt. The guest driver will use this indicator to avoid duplicate
forwarding in the guest OS.
Examples include bcast/mcast/unknown ucast pkts flooded to bridged ports.
We want to avoid both the device and the guest bridge driver flooding these
pkts, which would result in duplicates pkts on the wire. Packet sampling,
such as sFlow, can also use this technique to mark pkts for the guest OS to
record but otherwise drop.

rocker: don't queue receive pkts when port is disabled
Commit 6e99c63 ("net/socket: Drop net_socket_can_send") changed the
semantics around .can_receive for sockets to now require the device to
flush queued pkts when transitioning to a .can_receive=true state. Rocker
device was not flushing the queue on .can_receive=true transition, so the
receiver was stuck.
But, turns out we really don't want any queuing at all on the port when the
port is disabled, otherwise when the port transitions to enabled, we'd
receive and forward stale pkts that really should have been dropped. So,
let's remove .can_receive so avoid queuing and drop the pkt in .receive if
the port is disabled.

vmxnet3: Fix incorrect small packet padding
When running ESXi under qemu there is an issue with the ESXi guest
discarding packets that are too short. The guest discards any packets
under the normal minimum length for an ethernet packet (60). This
results in odd behaviour where other hosts or VMs on other hosts can
communicate with the ESXi guest just fine (since there's a physical NIC
somewhere doing padding), but VMs on the host and the host itself cannot
because the ARP request packets are too small for the ESXi host to
accept.
Someone in the past thought this was worth fixing, and added code to the
vmxnet3 qemu emulation such that if it is receiving packets smaller than
60 bytes to pad the packet out to 60. Unfortunately this code is wrong
(or at least in the wrong place). It does so BEFORE before taking into
account the vnet_hdr at the front of the packet added by the tap device.
As a result, it might add padding, but it never adds enough.
Specifically it adds 10 less (the length of the vnet_hdr) than it needs
to.
The following (hopefully "obviously correct") patch simply swaps the
order of processing the vnet header and the padding. With this patch an
ESXi guest is able to communicate with the host or other local VMs.

e1000: flush packets when link comes up
e1000_can_receive() checks the link up status register bit. If the bit
is clear, packets will be queued and the peer may disable receive to
avoid wasting CPU reading packets that cannot be delivered. The queue
must be flushed once the link comes back up again.
This patch fixes broken e1000 receive with Mac OS X Snow Leopard guests
and tap networking. Flushing the queue invokes the async send callback,
which re-enables tap fd read.

ich9: add TCO interface emulation
This interface provides some registers within a 32-byte range and can be
acessed through PCI-to-LPC bridge interface (PMBASE + 0x60).
It's commonly used as a watchdog timer to detect system lockups through
SMIs that are generated -- if TCO_EN bit is set -- on every timeout. If
NO_REBOOT bit is not set in GCS (General Control and Status register),
the system will be resetted upon second timeout if TCO_RLD register
wasn't previously written to prevent timeout.
This patch adds support to TCO watchdog logic and few other features
like mapping NMIs to SMIs (NMI2SMI_EN bit), system intruder detection,
etc. are not implemented yet.

crypto: introduce new module for computing hash digests
Introduce a new crypto/ directory that will (eventually) contain
all the cryptographic related code. This initially defines a
wrapper for initializing gnutls and for computing hashes with
gnutls. The former ensures that gnutls is guaranteed to be
initialized exactly once in QEMU regardless of CLI args. The
block quorum code currently fails to initialize gnutls so it
only works by luck, if VNC server TLS is not requested. The
hash APIs avoids the need to litter the rest of the code with
preprocessor checks and simplifies callers by allocating the
correct amount of memory for the requested hash.

The doc comments for bdrv_drain_all() and bdrv_drain() are outdated:
* The bdrv_drain() comment is a poor man's bdrv_lock()/bdrv_unlock()
which Fam Zheng is currently developing. Unfortunately this warning
was never really enough because devices keep submitting I/O and op
blockers don't prevent that.
* The bdrv_drain_all() comment is still partially correct but reflects
the nature of the implementation rather than API documentation.
Do make it clear that bdrv_drain() is only appropriate within an
AioContext. For anything spanning AioContexts you need
bdrv_drain_all().

vl: move rom_load_all after machine init done
On ARM, commit ac9d32e39664e060cd1b538ff190980d57ad69e4 postponed the
memory preparation for boot until the machine init done notifier. This
has for consequence to insert ROM at machine init done time.
However the rom_load_all function stayed called before the ROM are
inserted. As a consequence the rom_load_all function does not do
everything it is expected to do, on ARM.
It currently registers the ROM reset notifier but does not iterate through
the registered ROM list. the isrom field is not set properly. This latter
is used to report info in the monitor and also to decide whether the
rom->data can be freed on ROM reset notifier.
To fix that regression the patch moves the rom_load_all call after
machine init done. We also take the opportunity to rename the rom_load_all
function into rom_check_and_resgister_reset() and integrate the
rom_load_done in it.

Fix pba_offset initialization value for Chelsio T5 Virtual Function
device. The T5 hardware has a bug in it where it reports a Pending Interrupt
Bit Array Offset of 0x8000 for its SR-IOV Virtual Functions instead
of the 0x1000 that the hardware actually uses internally. As the hardware
doesn't return the correct pba_offset value, add a quirk to instead
return a hardcoded value of 0x1000 when a Chelsio T5 VF device is
detected.
This bug has been fixed in the Chelsio's next chip series T6 but there are
no plans to respin the T5 ASIC for this bug. It is just documented in the
T5 Errata and left it at that.

vfio: Unregister IOMMU notifiers when container is destroyed
On systems with guest visible IOMMU, adding a new memory region onto
PCI bus calls vfio_listener_region_add() for every DMA window. This
installs a notifier for IOMMU memory regions. The notifier is supposed
to be removed vfio_listener_region_del(), however in the case of mixed
PHB (emulated + VFIO devices) when last VFIO device is unplugged and
container gets destroyed, all existing DMA windows stay alive altogether
with the notifiers which are on the linked list which head was in
the destroyed container.
This unregisters IOMMU memory region notifier when a container is
destroyed.

kvm-all.c: add qemu_irq/gsi hash table and utility routines
VFIO platform device needs to setup irqfd but it does not know the
gsi corresponding to the device qemu_irq. This patch proposes to
store a hash table in kvm_state using the qemu_irq as key and the gsi
as a value.
kvm_irqchip_set_qemuirq_gsi allows to insert such a pair. The interrupt
controller is supposed to use it.
kvm_irqchip_[add, remove]_irqfd_notifier allows to setup/tear down
irqfd directly from the qemu_irq.

vfio: cpu: Use "real" page size API
This is system level code, and should only depend on the host page
size, not the target page size.
Note that HOST_PAGE_SIZE is misleadingly lead and is really aligning
to both host and target page size. Hence it's replacement with
REAL_HOST_PAGE_SIZE.

cpu-all: complete "real" host page size API
Currently the "host" page size alignment API is really aligning to both
host and target page sizes. There is the qemu_real_page_size which can
be used for the actual host page size but it's missing a mask and ALIGN
macro as provided for qemu_page_size. Complete the API. This allows
system level code that cares about the host page size to use a
consistent alignment interface without having to un-needingly align to
the target page size. This also reduces system level code dependency
on the cpu specific TARGET_PAGE_SIZE.

piix4/ich9: do not raise SMI on ACPI enable/disable commands
These commands are handled entirely by QEMU. Do not raise an SMI
when they happen, because Windows (at least 2008r2) expects these
commands to work and (depending on the value of APMC_EN at
startup) the firmware might not have installed an SMI handler.
When this happens (e.g. the kernel supports SMIs, or you are using
TCG, but you have used "-machine smm=off") RIP is moved to 0x38000
where there is no code to execute.

exec: skip MMIO regions correctly in cpu_physical_memory_write_rom_internal
Loading the BIOS in the mac99 machine is interesting, because there is a
PROM in the middle of the BIOS region (from 16K to 32K). Before memory
region accesses were clamped, when QEMU was asked to load a BIOS from
0xfff00000 to 0xffffffff it would put even those 16K from the BIOS file
into the region. This is weird because those 16K were not actually
visible between 0xfff04000 and 0xfff07fff. However, it worked.
After clamping was added, this also worked. In this case, the
cpu_physical_memory_write_rom_internal function split the write in
three parts: the first 16K were copied, the PROM area (second 16K) were
ignored, then the rest was copied.
Problems then started with commit 965eb2f (exec: do not clamp accesses
to MMIO regions, 2015-06-17). Clamping accesses is not done for MMIO
regions because they can overlap wildly, and MMIO registers can be
expected to perform full-width accesses based only on their address
(with no respect for adjacent registers that could decode to completely
different MemoryRegions). However, this lack of clamping also applied
to the PROM area! cpu_physical_memory_write_rom_internal thus failed
to copy the third range above, i.e. only copied the first 16K of the BIOS.
In effect, address_space_translate is expecting _something else_ to do
the clamping for MMIO regions if the incoming length is large. This
"something else" is memory_access_size in the case of address_space_rw,
so use the same logic in cpu_physical_memory_write_rom_internal.

Stop including qemu-common.h in memory.h
Including qemu-common.h from other header files is generally a bad
idea, because it means it's very easy to end up with a circular
dependency. For instance, if we wanted to include memory.h from
qom/cpu.h we'd end up with this loop:
memory.h -> qemu-common.h -> cpu.h -> cpu-qom.h -> qom/cpu.h -> memory.h
Remove the include from memory.h. This requires us to fix up a few
other files which were inadvertently getting declarations indirectly
through memory.h.
The biggest change is splitting the fprintf_function typedef out
into its own header so other headers can get at it without having
to include qemu-common.h.

target-arm: Split DISAS_YIELD from DISAS_WFE
Currently we use DISAS_WFE for both WFE and YIELD instructions.
This is functionally correct because at the moment both of them
are implemented as "yield this CPU back to the top level loop so
another CPU has a chance to run". However it's rather confusing
that YIELD ends up calling HELPER(wfe), and if we ever want to
implement real behaviour for WFE and SEV it's likely to trip us up.
Split out the yield codepath to use DISAS_YIELD and a new
HELPER(yield) function, and have HELPER(wfe) call HELPER(yield).

ahci: fix sdb fis semantics
There are two things to fix here:
The first one is subtle: the PxSACT register in the AHCI HBA has different
semantics from the field it is shadowing, the ACT field in the
Set Device Bits FIS.
In the HBA register, PxSACT acts as a bitfield indicating outstanding
NCQ commands where a set bit indicates a pending NCQ operation. The FIS
field however operates as an RWC register update to PxSACT, where a set
bit indicates a *successfully* completed command.
Correct the FIS semantics. At the same time, move the "clear finished"
action to the SDB FIS generation instead of the register read to mimick
how the other shadow registers work, which always just report the last
reported value from a FIS, and not the most current values which may
not have been reported by a FIS yet.
Lastly and more simply, SATA 3.2 section 13.6.4.2 (and later sections)
all specify that the Interrupt bit for the SDB FIS should always be set
to one for NCQ commands. That's currently the only time we generate this
FIS, so set it on all the time.

ahci: Do not map cmd_fis to generate response
The Register D2H FIS should copy the current values of
the registers instead of just parroting back the same
values the guest sent back to it.
In this case, the SECTOR COUNT variables are actually
not generally meaningful in terms of standard commands
(See ATA8-AC3 Section 9.2 Normal Outputs), so it actually
probably doesn't matter what we put in here.
Meanwhile, we do need to use the Register update FIS from
the NCQ pathways (in error cases), so getting rid of
references to cur_cmd here is a win for AHCI concurrency.

ahci: add get_cmd_header helper
cur_cmd is an internal bookmark that points to the
current AHCI Command Header being processed by the
AHCI state machine. With NCQ needing to occasionally
rely on some of the same AHCI helpers, we cannot use
cur_cmd and will need to grab explicit pointers instead.
In an attempt to begin relying on the cur_cmd pointer
less, add a helper to let us specifically get the pointer
to the command header of particular interest.

ahci: add cmd header to ncq transfer state
While the rest of the AHCI device can rely on a single bookmarked
pointer for the AHCI Command Header currently being processed, NCQ
is asynchronous and may have many commands in flight simultaneously.
Add a cmdh pointer to the ncq_tfs object and make the sglist prepare
function take an AHCICmdHeader pointer so we can be explicit about
where we'd like to build SGlists from.

ahci: correct ncq sector count
uint16_t isn't enough to hold the real sector count, since a value of
zero implies a full 64K sectors, so we need a uint32_t here.
We *could* cheat and pretend that this value is 0-based and fit it in
a uint16_t, but I'd rather waste 2 bytes instead of a future dev's
10 minutes when they forget to +1/-1 accordingly somewhere.

Date: Sat Jul 4 02:06:04 2015 -0400
ide: add limit to .prepare_buf()
prepare_buf should not always grab as many descriptors
as it can, sometimes it should self-limit.
For example, an NCQ transfer of 1 sector with a PRDT that
describes 4GiB of data should not copy 4GiB of data, it
should just transfer that first 512 bytes.
PIO is not affected, because the dma_buf_rw dma helpers
already have a byte limit built-in to them, but DMA/NCQ
will exhaust the entire list regardless of requested size.
AHCI 1.3 specifies in section 6.1.6 Command List Underflow that
NCQ is not required to detect underflow conditions. Non-NCQ
pathways signal underflow by writing to the PRDBC field, which
will already occur by writing the actual transferred byte count
to the PRDBC, signaling the underflow.
Our NCQ pathways aren't required to detect underflow, but since our DMA
backend uses the size of the PRDT to determine the size of the transer,
if our PRDT is bigger than the transaction (the underflow condition) it
doesn't cost us anything to detect it and truncate the PRDT.
This is a recoverable error and is not signaled to the guest, in either
NCQ or normal DMA cases.
For BMDMA, the existing pathways should see no guest-visible difference,
but any bytes described in the overage will no longer be transferred
before indicating to the guest that there was an underflow.

libqos/ahci: fix memory management bugs
There's a handful of trivial bugs in the libqos/ahci functions,
squish them together.
- Zero cached pointers after freeing them
- The Command List Buffer is an array of 32x 32 byte structures, not
32x 8 byte pointers -- it's 1MiB, not 256 bytes. Zero it ALL.
- Free the correct command in ahci_pick_cmd.

ahci: Do not ignore memory access read size
The only guidance the AHCI specification gives on memory access is:
"Register accesses shall have a maximum size of 64-bits; 64-bit access
must not cross an 8-byte alignment boundary."
I interpret this to mean that aligned or unaligned 1, 2 and 4 byte
accesses should work, as well as aligned 8 byte accesses.
In practice, a real Q35/ICH9 responds to 1, 2, 4 and 8 byte reads
regardless of alignment. Windows 7 can be observed making 1 byte
reads to the middle of 32 bit registers to fetch error codes.
Introduce a wrapper to support unaligned accesses to AHCI.
This wrapper will support aligned 8 byte reads, but will make
no effort to support unaligned 8 byte reads, which although they
will work on real hardware, are not guaranteed to work and do
not appear to be used by either Windows or Linux.

s390x/migration: Introduce 2.4 machine
The section footer changes commit f68945d42bab ("Add a protective
section footer") and commit 37fb569c0198 ("Disable section footers
on older machine types") broke migration for any non-versioned
machines.
This pinpoints a problem of s390-ccw machines: it needs to
be versioned to be compatible with future changes in common
code data structures such as section footers.
Let's introduce a version scheme for s390-ccw-virtio machines.
We will use the old s390-ccw-virtio name as alias to the latest
version as all existing libvirt XML for the ccw type were expanded
by libvirt to that name.
The only downside of this patch is, that the old alias s390-ccw
will no longer be available as machines can have only one alias,
but it should not really matter.

s390x/gdb: synchronize cpu state after modifying acrs
Whenever we touch the access control registers, we have to make sure that
the values will make it into kvm. Otherwise the change will simply be lost.
When synchronizing qemu and kvm, a normal KVM_PUT_RUNTIME_STATE does not take
care of these registers. Let's simply trigger a KVM_PUT_FULL_STATE sync,
so the values will directly be written to kvm. The performance overhead can
be ignored and this is much cleaner than manually writing these registers to kvm
via our two supported ways.

s390x/ipl: Fix boot if no bootindex was specified
commit fa92e218df1d ("s390x/ipl: avoid sign extension") introduced
a regression:
qemu-system-s390x -drive file=image.qcow,format=qcow2
does not boot, the bios states
"No virtio-blk device found!"
adding bootindex=1 does boot.
The reason is that the uint32_t as return value will not do the right
thing for the return -1 (default without bootindex).
The bios itself, will interpret a 64bit -1 as autodetect (but it will
interpret 32bit -1 as ccw device address ff.ff.ffff)

block: Fix dirty bitmap in bdrv_co_discard
Unsetting dirty globally with discard is not very correct. The discard may zero
out sectors (depending on can_write_zeroes_with_unmap), we should replicate
this change to destination side to make sure that the guest sees the same data.
Calling bdrv_reset_dirty also troubles mirror job because the hbitmap iterator
doesn't expect unsetting of bits after current position.
So let's do it the opposite way which fixes both problems: set the dirty bits
if we are to discard it.

block: Add bdrv_get_block_status_above
Like bdrv_is_allocated_above, this function follows the backing chain until seeing
BDRV_BLOCK_ALLOCATED. Base is not included.
Reimplement bdrv_is_allocated on top.
[Initialized bdrv_co_get_block_status_above() ret to 0 to silence
mingw64 compiler warning about the unitialized variable. assert(bs !=
base) prevents that case but I suppose the program could be compiled
with -DNDEBUG.

qapi: Rename 'dirty-bitmap' mode to 'incremental'
If we wish to make differential backups a feature that's easy to access,
it might be pertinent to rename the "dirty-bitmap" mode to "incremental"
to make it clear what /type/ of backup the dirty-bitmap is helping us
perform.
This is an API breaking change, but 2.4 has not yet gone live,
so we have this flexibility.

block/iscsi: add support for request timeouts
libiscsi starting with 1.15 will properly support timeout of iscsi
commands. The default will remain no timeout, but this can
be changed via cmdline parameters, e.g.:
qemu -iscsi timeout=30 -drive file=iscsi://...
If a timeout occurs a reconnect is scheduled and the timed out command
will be requeued for processing after a successful reconnect.
The required API call iscsi_set_timeout is present since libiscsi
1.10 which was released in October 2013. However, due to some bugs
in the libiscsi code the use is not recommended before version 1.15.
Please note that this patch bumps the libiscsi requirement to 1.10
to have all function and macros defined. The patch fixes also a
off-by-one error in the NOP timeout calculation which was fixed
while touching these code parts.

kvm: First step to push iothread lock out of inner run loop
This opens the path to get rid of the iothread lock on vmexits in KVM
mode. On x86, the in-kernel irqchips has to be used because we otherwise
need to synchronize APIC and other per-cpu state accesses that could be
changed concurrently.
Regarding pre/post-run callbacks, s390x and ARM should be fine without
specific locking as the callbacks are empty. MIPS and POWER require
locking for the pre-run callback.
For the handle_exit callback, it is non-empty in x86, POWER and s390.
Some POWER cases could do without the locking, but it is left in
place for now.

memory: let address_space_rw/ld*/st* run outside the BQL
The MMIO case is further broken up in two cases: if the caller does not
hold the BQL on invocation, the unlocked one takes or avoids BQL depending
on the locking strategy of the target memory region and its coalesced
MMIO handling. In this case, the caller should not hold _any_ lock
(a friendly suggestion which is disregarded by virtio-scsi-dataplane).

main-loop: introduce qemu_mutex_iothread_locked
This function will be used to avoid recursive locking of the iothread lock
whenever address_space_rw/ld*/st* are called with the BQL held, which is
almost always the case.
Tracking whether the iothread is owned is very cheap (just use a TLS
variable) but requires some care because now the lock must always be
taken with qemu_mutex_lock_iothread(). Previously this wasn't the case.
Outside TCG mode this is not a problem. In TCG mode, we need to be
careful and avoid the "prod out of compiled code" step if already
in a VCPU thread. This is easily done with a check on current_cpu,
i.e. qemu_in_vcpu_thread().
Hopefully, multithreaded TCG will get rid of the whole logic to kick
VCPUs whenever an I/O event occurs!

Fix irq route entries exceeding KVM_MAX_IRQ_ROUTES
Last month, we experienced several guests crash(6cores-8cores), qemu logs
display the following messages:
qemu-system-x86_64: /build/qemu-2.1.2/kvm-all.c:976:
kvm_irqchip_commit_routes: Assertion `ret == 0' failed.
After analysis and verification, we can confirm it's irq-balance
daemon(in guest) leads to the assertion failure. Start a 8 core guest with
two disks, execute the following scripts will reproduce the BUG quickly:
irq_affinity.sh
========================================================================
vda_irq_num=25
vdb_irq_num=27
while [ 1 ]
do
for irq in {1,2,4,8,10,20,40,80}
do
echo $irq > /proc/irq/$vda_irq_num/smp_affinity
echo $irq > /proc/irq/$vdb_irq_num/smp_affinity
dd if=/dev/vda of=/dev/zero bs=4K count=100 iflag=direct
dd if=/dev/vdb of=/dev/zero bs=4K count=100 iflag=direct
done
done
========================================================================
QEMU setup static irq route entries in kvm_pc_setup_irq_routing(), PIC and
IOAPIC share the first 15 GSI numbers, take up 23 GSI numbers, but take up
38 irq route entries. When change irq smp_affinity in guest, a dynamic route
entry may be setup, the current logic is: if allocate GSI number succeeds,
a new route entry can be added. The available dynamic GSI numbers is
1021(KVM_MAX_IRQ_ROUTES-23), but available irq route entries is only
986(KVM_MAX_IRQ_ROUTES-38), GSI numbers greater than route entries.
irq-balance's behavior will eventually leads to total irq route entries
exceed KVM_MAX_IRQ_ROUTES, ioctl(KVM_SET_GSI_ROUTING) fail and
kvm_irqchip_commit_routes() trigger assertion failure.
This patch fix the BUG.

Split off this routine into a new function virtio_ccw_reset_virtio()

and the base subchannel device clear.

include/exec: Move tb hash functions out
This is one of very few things in exec-all with a genuine CPU
architecture dependency. Move these hashing helpers to a new
header to trim exec-all.h down to a near architecture-agnostic
header.
The defs are only used by cpu-exec and translate-all which are both
arch-obj's so the new tb-hash.h has no core code usage.

hw/arm/virt: Make block devices default to virtio
Now we have virtio-pci, we can make the virt board's default block
device type be IF_VIRTIO. This allows users to use simplified
command lines that don't have to explicitly create virtio-pci-blk
devices; the -hda &c very short options now also work.
This means we also need to set no_cdrom to avoid getting a
default cdrom device -- this is needed because the virtio-blk
device will fail if it is connected to a block backend with
no media, which is what the default cdrom device typically is.
Providing a cdrom with media via -cdrom will succeed, but silently
create a device with non-removable medium. this is probably
not really what the user wants, but is the best we can do now.
Note that this change means that some command lines which used
to work (by accident) will stop working. Where a drive was connected
manually to a device but without 'if=none' being specified, we
used to treat this as an IDE drive, which we would then not autoplug
because the board doesn't support IDE. Now we will treat it as a
virtio disk and autoplug it, which means the attempt to use the
drive manually will fail:
qemu-system-arm: -drive file=img.qcow2,id=foo: Drive 'foo' is already
in use because it has been automatically connected to another device
(did you need 'if=none' in the drive options?)
The command line will have to be changed to include 'if=none', as the
error message suggests.

qdev-properties-system: Improve error message for drive assignment conflict
If the user forgot if=none on their drive specification they're likely
to get an error message because the drive is assigned once automatically
by QEMU and once by the manual id=/drive= user command line specification.
Improve the error message produced in this case to explicitly guide the
user towards if=none.
We rephrase the "drive conflict but not for an if=something" error as
well to keep the wording in line.
The two cases that change are:
(1) Drive specified as to be auto-connected and also manually connected
(and the board does handle this if= type):
qemu-system-x86_64 -nodefaults -display none \
-drive if=scsi,file=tmp.qcow2,id=foo -device ide-hd,drive=foo
Previously:
qemu-system-x86_64: -device ide-hd,drive=foo: Property 'ide-hd.drive'
can't take value 'foo', it's in use
Now:
qemu-system-x86_64: -device ide-hd,drive=foo: Drive 'foo' is already in
use because it has been automatically connected to another device (did
you need 'if=none' in the drive options?)
(2) Drive specified to be manually connected in two different ways:
qemu-system-x86_64 -nodefaults -display none \
-drive if=none,file=tmp.qcow2,id=foo -device ide-hd,drive=foo \
-device ide-hd,drive=foo
Previously:
qemu-system-x86_64: -device ide-hd,drive=foo: Property 'ide-hd.drive'
can't take value 'foo', it's in use
Now:
qemu-system-x86_64: -device ide-hd,drive=foo: Drive 'foo' is already in
use by another device

Instead of having set_pointer() call a parse callback which returns
an error number that we then convert to an Error string with
error_set_from_qdev_prop_error(), make the parse callback take an
Error** and set the error itself. This will allow parse routines
to provide more helpful error messages than the generic ones.

target-mips: raise RI exceptions when FIR.PS = 0
64-bit paired-single (PS) floating point data type is optional in the
pre-Release 6.
It has to raise RI exception when PS type is not implemented. (FIR.PS = 0)
(The PS data type is removed in the Release 6.)
Loongson-2E and Loongson-2F don't have any implementation field in
FCSR0(FIR) but do support PS data format, therefore for these cores RI will
not be signalled regardless of PS bit.

hw/mips: Do not clear BEV for MIPS malta kernel load
The BEV flag controls whether the boot exception vector is still
in place when starting a kernel. When cleared the exception vector
at EBASE (or hard coded address of 0x80000000) is used instead.
The early stages of the linux kernel would benefit from BEV still
being set to ensure any faults get handled by the boot rom exception
handlers. This is a moot point for system qemu as there aren't really
any BEV handlers, but there are other good reasons to change this...
The UHI (semi-hosting interface) defines special behaviours depending
on whether an application starts in an environment with BEV set or
cleared. When BEV is set then UHI assumes that a bootloader is
relatively dumb and has no advanced exception handling logic.
However, when BEV is cleared then UHI assumes that the bootloader
has the ability to handle UHI exceptions with its exception handlers
and will unwind and forward UHI SYSCALL exceptions to the exception
vector that was installed prior to running the application.

hw/pci-bridge: format special OFW unit address for PXB host
We have agreed that OpenFirmware device paths in the "bootorder" fw_cfg
file should follow the pattern
/pci@i0cf8,%x/...
for devices that live behind an extra root bus. The extra root bus in
question is the %x'th among the extra root buses. (In other words, %x
gives the position of the affected extra root bus relative to the other
extra root buses, in bus_nr order.) %x starts at 1, and is formatted in
hex.
The portion of the unit address that comes before the comma is dynamically
taken from the main host bridge, similarly to sysbus_get_fw_dev_path().

hw/core: explicit OFW unit address callback for SysBusDeviceClass
The sysbus_get_fw_dev_path() function formats OpenFirmware device path
nodes ("driver-name@unit-address") for sysbus devices. The first choice
for "unit-address" is the base address of the device's first MMIO region.
The second choice is its first IO port.
However, if two sysbus devices with the same "driver-name" lack both MMIO
and PIO resources, then there is no good way to distinguish them based on
their OFW nodes, because in this case unit-address is omitted completely
for both devices. An example is TYPE_PXB_HOST ("pxb-host").
For the sake of such devices, introduce the explicit_ofw_unit_address()
"virtual member function". With this function, each sysbus device in the
same SysBusDeviceClass can state its own address.

hw/pci-bridge: disable SHPC in PXB
OVMF downloads the ACPI linker/loader script from QEMU when the edk2 PCI
Bus driver globally signals the firmware that PCI enumeration and resource
allocation have completed. At this point QEMU regenerates the ACPI payload
in an fw_cfg read callback, and this is when the PXB's _CRS gets
populated.
Unfortunately, when this happens, the PCI_COMMAND_MEMORY bit is clear in
the root bus's command register, *unlike* under SeaBIOS. The consequences
unfold as follows:
- When build_crs() fetches dev->io_regions[i].addr, it is all-bits-one,
because pci_update_mappings() --> pci_bar_address() calculated it as
PCI_BAR_UNMAPPED, due to the PCI_COMMAND_MEMORY bit being clear.
- Consequently, the SHPC MMIO BAR (bar 0) of the bridge is not added to
the _CRS, *despite* having been programmed in PCI config space.
- Similarly, the SHPC MMIO BAR of the PXB is not removed from the main
root bus's DWordMemory descriptor.
- Guest OSes (Linux and Windows alike) notice the pre-programmed SHPC BAR
within the PXB's config space, and notice that it conflicts with the
main root bus's memory resource descriptors. Linux reports
pci 0000:04:00.0: BAR 0: can't assign mem (size 0x100)
pci 0000:04:00.0: BAR 0: trying firmware assignment [mem
0x88200000-0x882000ff 64bit]
pci 0000:04:00.0: BAR 0: [mem 0x88200000-0x882000ff 64bit] conflicts
with PCI Bus 0000:00 [mem
0x88200000-0xfebfffff]
While Windows Server 2012 R2 reports
https://technet.microsoft.com/en-us/library/cc732199%28v=ws.10%29.aspx
This device cannot find enough free resources that it can use. If you
want to use this device, you will need to disable one of the other
devices on this system. (Code 12)
This issue was apparently encountered earlier, see the "hack" in:
https://lists.nongnu.org/archive/html/qemu-devel/2015-01/msg02983.html
and the current hole-punching logic in build_crs() and build_ssdt() is
probably supposed to remedy exactly that problem -- however, for OVMF they
don't work, because at the end of the PCI enumeration and resource
allocation, which cues the ACPI linker/loader client, the command register
is clear.
The "shpc" property of "pci-bridge", introduced in the previous patches,
allows us to disable the standard hotplug controller cleanly, eliminating
the SHPC bar and the conflict.

util/qemu-sockets: improve ai_flag hints for ipv6 hosts
*) Do not use AI_ADDRCONFIG on listening sockets, because this flag
makes it impossible to explicitly listen on '127.0.0.1' if no global
ipv4 address is configured additionally, making this a very
uncomfortable option.
*) Add AI_V4MAPPED hint for connecting sockets.
If your system is globally only connected via ipv6 you often still want
to be able to use '127.0.0.1' and 'localhost' (even if localhost doesn't
also have an ipv6 entry).
For example, PVE - unless explicitly asking for insecure mode - uses
ipv4 loopback addresses with QEMU for live migrations tunneled over SSH.
These fail to start because AI_ADDRCONFIG makes getaddrinfo refuse to
work with '127.0.0.1'.
As for the AI_V4MAPPED flag: glibc uses it by default, and providing
non-0 flags removes it. I think it makes sense to use it.
I also want to point out that glibc explicitly sidesteps POSIX standards
when passing 0 as hints by then assuming both AI_V4MAPPED and
AI_ADDRCONFIG (the latter being a rather weird choice IMO), while
according to POSIX.1-2001 it should be assumed 0. (glibc considers its
choice an improvement.)
Since either AI_CANONNAME or AI_PASSIVE are passed in our cases, glibc's
default flags in turn are disabled again unless explicitly added, which
I do with this patch.

Furthermore, for libraries used internally by the library
(this is the way nss and glib are used by libcacard),

remove libdecnumber/dpd/decimal128Local.h
Commit 72ac97cdfc added two equivalent versions of decimal128Local.h,
one in libdecnumber/dpd/ and another in include/libdecnumber/dpd/.
Being identical by the code, the two files however differs in the
licensing terms. The one in libdecnumber/dpd/ (which is being
removed by this patch) is licensed as GPL3.1 (plus gcc runtime
exception), which, as far as I know, is not compatible with GPL-2.
This file is not used (it is included from
include/libdecnumber/dpd/decimal128.h, so version in include/ is
used).
More, the version in include/ can also be removed, since none
of the 3 defines from that file are actually used by the code.
Even more, one of the defines from there, decimal128SetSign,
is redefined (to equivalent value) in libdecnumber/dpd/decimal128.c,
but again, never used.
What a mess...

Revert "xen-hvm: increase maxmem before calling xc_domain_populate_physmap"
This reverts commit c1d322e6048796296555dd36fdd102d7fa2f50bf.
The original commit fixes a bug when assigning a large number of
devices which require option roms to a guest. (One known
configuration that needs extra memory is having more than 4 emulated
NICs assigned. Three or fewer NICs seems to work without this
functionality.)
However, by unilaterally increasing maxmem, it introduces two
problems.
First, now libxl's calculation of the required maxmem during migration
is broken -- any guest which exercised this functionality will fail on
migration. (Guests which have the default number of devices are not
affected.)
Secondly, it makes it impossible for a higher-level toolstack or
administer to predict how much memory a VM will actually use, making
it much more difficult to effectively use all of the memory on a
machine.

balloon: add a feature bit to let Guest OS deflate balloon on oom
Excessive virtio_balloon inflation can cause invocation of OOM-killer,
when Linux is under severe memory pressure. Various mechanisms are
responsible for correct virtio_balloon memory management. Nevertheless it
is often the case that these control tools does not have enough time to
react on fast changing memory load. As a result OS runs out of memory and
invokes OOM-killer. The balancing of memory by use of the virtio balloon
should not cause the termination of processes while there are pages in the
balloon. Now there is no way for virtio balloon driver to free memory at
the last moment before some process get killed by OOM-killer.
This does not provide a security breach as balloon itself is running
inside Guest OS and is working in the cooperation with the host. Thus
some improvements from Guest side should be considered as normal.
To solve the problem, introduce a virtio_balloon callback which is
expected to be called from the oom notifier call chain in out_of_memory()
function. If virtio balloon could release some memory, it will make the
system return and retry the allocation that forced the out of memory
killer to run.
This behavior should be enabled if and only if appropriate feature bit
is set on the device. It is off by default.
This functionality was recently merged into vanilla Linux.

raw-posix: Introduce hdev_is_sg()
Until now, an SG device was identified only by checking if its path
started with "/dev/sg". Then, hdev_open() would set the bs->sg flag
accordingly. The patch relies on the actual properties of the device
instead of the specified file path.
To this end, test for an SG device (e.g. /dev/sg0) by ensuring that
all of the following holds:
- The specified file name corresponds to a character device
- The device supports the SG_GET_VERSION_NUM ioctl
- The device supports the SG_GET_SCSI_ID ioctl

raw-posix: DPRINTF instead of DEBUG_BLOCK_PRINT
Building the QEMU tools fails if we #define DEBUG_BLOCK inside
block/raw-posix.c. Here instead of adding qemu-log.o in block-obj-y
so that DEBUG_BLOCK_PRINT can be used, we substitute the latter with
a simple DPRINTF() (that does not cause bit-rot).

Fix migration in case of scsi-generic
During migration, QEMU uses fsync()/fdatasync() on the open file
descriptor for read-write block devices to flush data just before
stopping the VM.
However, fsync() on a scsi-generic device returns -EINVAL which
causes the migration to fail. This patch skips flushing data in case
of an SG device, since submitting SCSI commands directly via an SG
character device (e.g. /dev/sg0) bypasses the page cache completely,
anyway.
Note that fsync() not only flushes the page cache but also the disk
cache. The scsi-generic device never sends flushes, and for
migration it assumes that the same SCSI device is used by the
destination host, so it does not issue any SCSI SYNCHRONIZE CACHE
(10) command.
Finally, remove the bdrv_is_sg() test from iscsi_co_flush() since
this is now redundant (we flush the underlying protocol at the end
of bdrv_co_flush() which, with this patch, we never reach).

virtio-blk: Use blk_drain() to drain IO requests
Each call of the virtio_blk_reset() function calls blk_drain_all(),
which works for all existing BlockDriverStates, while draining only
one is needed.
This patch replaces blk_drain_all() by blk_drain() in
virtio_blk_reset(). virtio_blk_data_plane_stop() should be called
after draining because it restores vblk->complete_request.

throttle: Check current timers before updating any_timer_armed[]
Calling throttle_group_config() cancels all timers from a particular
BlockDriverState, so any_timer_armed[] should be updated accordingly.
However, with the current code it may happen that a timer is armed in
a different BlockDriverState from the same group, so any_timer_armed[]
would be set to false in a situation where there is still a timer
armed.
The consequence is that we might end up with two timers armed. This
should not have any noticeable impact however, since all accesses to
the ThrottleGroup are protected by a lock, and the situation would
become normal again shortly thereafter as soon as all timers have been
fired.
The correct way to solve this is to check that we're actually
cancelling a timer before updating any_timer_armed[].

block: Let bdrv_drain_all() to call aio_poll() for each AioContext
After the commit 9b536adc ("block: acquire AioContext in
bdrv_drain_all()") the aio_poll() function got called for every
BlockDriverState, in assumption that every device may have its own
AioContext. If we have thousands of disks attached, there are a lot of
BlockDriverStates but only a few AioContexts, leading to tons of
unnecessary aio_poll() calls.
This patch changes the bdrv_drain_all() function allowing it find shared
AioContexts and to call aio_poll() only for unique ones.

qmp: Wean off qerror_report()
The traditional QMP command handler interface
int qmp_FOO(Monitor *mon, const QDict *params, QObject **ret_data);
doesn't provide for returning an Error object. Instead, the handler
is expected to stash it in the monitor with qerror_report().
When we rebased QMP on top of QAPI, we didn't change this interface.
Instead, commit 776574d introduced "middle mode" as a temporary aid
for converting existing QMP commands to QAPI one by one. More than
three years later, we're still using it.
Middle mode has two effects:
* Instead of the native input marshallers
static void qmp_marshal_input_FOO(QDict *, QObject **, Error **)
it generates input marshallers conforming to the traditional QMP
command handler interface.
* It suppresses generation of code to register them with
qmp_register_command()
This permits giving them internal linkage.
As long as we need qmp-commands.hx, we can't use the registry behind
qmp_register_command(), so the latter has to stay for now.
The former has to go to get rid of qerror_report(). Changing all QMP
commands to fit the QAPI mold in one go was impractical back when we
started, but by now there are just a few stragglers left:
do_qmp_capabilities(), qmp_qom_set(), qmp_qom_get(), qmp_object_add(),
qmp_netdev_add(), do_device_add().
Switch middle mode to generate native input marshallers, and adapt the
stragglers. Simplifies both the monitor code and the stragglers.
Rename do_qmp_capabilities() to qmp_capabilities(), and
do_device_add() to qmp_device_add, because that's how QMP command
handlers are named today.

qerror_report_err() by error_report_err().
The uses in qemu-img.c, qemu-io.c, qemu-nbd.c and under tests/ are
clearly not in QMP context.
The uses in vl.c aren't either, because the only QMP command handlers
there are qmp_query_status() and qmp_query_machines(), and they don't
call it.
Remaining uses:
* drive_def(): Command line -drive and such, HMP drive_add and pci_add
* hmp_chardev_add(): HMP chardev-add
* monitor_parse_command(): HMP core
* tmp_config_parse(): Command line -tpmdev
* net_host_device_add(): HMP host_net_add
* net_client_parse(): Command line -net and -netdev
* qemu_global_option(): Command line -global
* vnc_parse_func(): Command line -display, -vnc, default display, HMP
change, QMP change. Bummer.
* qemu_pci_hot_add_nic(): HMP pci_add
* usb_net_init(): Command line -usbdevice, HMP usb_add
Propagate errors through qemu_opts_parse(). Create a convenience
function qemu_opts_parse_noisily() that passes errors to
error_report_err(). Switch all non-QMP users outside tests to it.
That leaves vnc_parse_func(). Propagate errors through it. Since I'm
touching it anyway, rename it to vnc_parse().

qdev-monitor: Fix check for full bus
Property bus has always been too screwed up to be really usable for
values other than plain bus IDs. This just fixes a bug that crept in
in commit 1395af6 "qdev: add a maximum device allowed field for the
bus."
It doesn't always fail when it should:
$ qemu-system-x86_64 -nodefaults -device virtio-serial-pci -device virtio-rng-device,bus=pci.0/virtio-serial-pci/virtio-bus
Happily plugs the virtio-rng-device into the virtio-bus provided by
virtio-serial-pci, even though its only slot is already occupied by a
virtio-serial-device.
And sometimes fails when it shouldn't:
$ qemu-system-x86_64 -nodefaults -device virtio-serial-pci -device virtserialport,bus=virtio-bus/virtio-serial-device
Yes, the virtio-bus is full, but the virtio-serial-bus provided by
virtio-serial-device isn't, and that's the one we're trying to use.
Root cause: we check "bus full" when we resolve the first element of
the path. That's the correct one only when it's also the last one.
Fix by moving the "bus full" check to right before we return a bus.

qdev-monitor: Stop error avalanche in qbus_find_recursive()
Reproducer:
$ qemu-system-x86_64 -nodefaults -device virtio-rng-pci -device virtio-rng-pci -device virtio-rng-device,bus=virtio-bus
qemu-system-x86_64: -device virtio-rng-device,bus=virtio-bus: Bus 'virtio-bus' is full

qemu-system-x86_64: -device virtio-rng-device,bus=virtio-bus: Bus 'virtio-bus' not found
qbus_find_recursive() reports the "is full" error itself, and leaves
reporting "not found" to its caller. The result is confusion. Write
it a function contract that permits leaving all error reporting to the
caller, and implement it. Update callers to detect and report "is
full".
Screwed up when commit 1395af6 added the max_dev limit and the "is
full" error condition to enforce it.

monitor: Split mon_get_cpu fn to remove ENV_GET_CPU
The monitor currently has one helper, mon_get_cpu() which will return
an env pointer. The target specific users of this API want an env, but
all the target agnostic users really just want the cpu pointer. These
users then need to use the target-specifically defined ENV_GET_CPU to
navigate back up to the CPU from the ENV. Split the API for the two
uses cases to remove all need for ENV_GET_CPU.

m68k: fix usp processing on interrupt entry and exception exit
The action to potentially switch sp register is not occurring at the correct
point in the interrupt entry or exception exit sequences.
For the interrupt entry case the sp on entry is used to create the stack
exception frame - but this may well be the user stack pointer, since we
haven't done the switch yet. Re-order the flow to switch the sp regs then
use the current sp to create the exception frame.
For the return from exception case the code is unwinding the sp after
switching sp registers. But it should always unwind the supervisor sp
first, then carry out any required sp switch.
Note that these problems don't effect operation unless the user sp bit is
set in the CACR register. Only a single sp is used in the default power up
state. Previously Linux only used this single sp mode. But modern versions
of Linux use the user sp mode now, so we need correct behavior for Linux
to work.

qdev: Deprecated qdev_init() is finally unused, drop

qerror_report_err() is a transitional interface to help with
converting existing monitor commands to QMP. It should not be used
elsewhere.
All code has been modernized to avoid qdev_init() and its
inappropriate error handling. We can finally drop it.

qom: Don't pass string table to object_get_enum() function
Now that properties can be explicitly registered as an enum
type, there is no need to pass the string table to the
object_get_enum() function. The object property registration
already has a pointer to the string table.
In changing this method signature, the hostmem backend object
has to be converted to use the new enum property registration
code, which simplifies it somewhat.

qom: Add an object_property_add_enum() helper function
A QOM property can be parsed as enum using the visit_type_enum()
helper function, but this forces callers to use the more complex
generic object_property_add() method when registering it. It
also requires that users of that object have access to the
string map when they want to read the property value.
This patch introduces a specialized object_property_add_enum()
method which simplifies the use of enum properties, so the
setters/getters directly get passed the int value.
typedef enum {
MYDEV_TYPE_FROG,
MYDEV_TYPE_ALLIGATOR,
MYDEV_TYPE_PLATYPUS,
MYDEV_TYPE_LAST
} MyDevType;
Then provide a table of enum <-> string mappings
static const char *const mydevtypemap[MYDEV_TYPE_LAST + 1] = {
[MYDEV_TYPE_FROG] = "frog",
[MYDEV_TYPE_ALLIGATOR] = "alligator",
[MYDEV_TYPE_PLATYPUS] = "platypus",
[MYDEV_TYPE_LAST] = NULL,
};
Assuming an object struct of
typedef struct {
Object parent_obj;
MyDevType devtype;
...other fields...
} MyDev;
The property can then be registered as follows:
static int mydev_prop_get_devtype(Object *obj,
Error **errp G_GNUC_UNUSED)
{
MyDev *dev = MYDEV(obj);
return dev->devtype;
}
static void mydev_prop_set_devtype(Object *obj,
int value,
Error **errp G_GNUC_UNUSED)
{
MyDev *dev = MYDEV(obj);
dev->devtype = value;
}
object_property_add_enum(obj, "devtype",
mydevtypemap, "MyDevType",
mydev_prop_get_devtype,
mydev_prop_set_devtype,
NULL);
Note there is no need to check the range of 'value' in
the setter, because the string->enum conversion code will
have already done that and reported an error as required.

qom: Add object_new_with_props() / object_new_withpropv() helpers
It is reasonably common to want to create an object, set a
number of properties, register it in the hierarchy and then
mark it as complete (if a user creatable type). This requires
quite a lot of error prone, verbose, boilerplate code to achieve.
First a pair of functions object_set_props() / object_set_propv()
are added which allow for a list of objects to be set in
one single API call.
Then object_new_with_props() / object_new_with_propv() constructors
are added which simplify the sequence of calls to create an
object, populate properties, register in the object composition
tree and mark the object complete, into a single method call.
Usage would be:
Error *err = NULL;
Object *obj;
obj = object_new_with_propv(TYPE_MEMORY_BACKEND_FILE,
object_get_objects_root(),
"hostmem0",
&err,
"share", "yes",
"mem-path", "/dev/shm/somefile",
"prealloc", "yes",
"size", "1048576",
NULL);
Note all property values are passed in string form and will
be parsed into their required data types, using normal QOM
semantics for parsing from string format.

vl: Create (most) objects before creating chardev backends
Some types of object must be created before chardevs, other types of
object must be created after chardevs. As such there is no option but
to create objects in two phases.
This takes the decision to create as many object types as possible
right away before anyother backends are created, and only delay
creation of those few which have an explicit dependency on the
chardevs. Hopefully the set which need delaying will remain small
over time.

semihosting: add --semihosting-config arg sub-argument
Add new "arg" sub-argument to the --semihosting-config allowing the user
to pass multiple input arguments separately. It is required for example
by UHI semihosting to construct argc and argv.
Also, update ARM semihosting to support new option (at the moment it is
the only target which cares about arguments).
If the semihosting is enabled and no semihosting args have been specified,
then fall back to -kernel/-append. The -append string is split on whitespace
before initializing semihosting.argv[1..n]; this is different from what
QEMU MIPS machines' pseudo-bootloaders do (i.e. argv[1] contains the whole
-append), but is more intuitive from UHI user's point of view and Linux
kernel just does not care as it concatenates argv[1..n] into single cmdline
string anyway.

target-arm: Do not reset sysregs marked as ALIAS
cp_reg_reset() is called from g_hash_table_foreach() which does not
define a specific ordering of the hash table iteration. Thus doing reset
for registers marked as ALIAS would give an ambiguous result when
resetvalue is different for original and alias registers. Exit
cp_reg_reset() early when passed an alias register. Then clean up alias
register definitions from needless resetvalue and resetfn.
In particular, this fixes a bug in the handling of the PMCR register,
which had different resetvalues for its 32 and 64-bit views.

hw/arm/sysbus-fdt: enable vfio-calxeda-xgmac dynamic instantiation
This patch allows the instantiation of the vfio-calxeda-xgmac device
from the QEMU command line (-device vfio-calxeda-xgmac,host="<device>").
A specialized device tree node is created for the guest, containing
compat, dma-coherent, reg and interrupts properties.

target-arm: Add the Cortex-M4 CPU
This patch adds the Cortex-M4 CPU. The M4 is basically the same as
the M3, the main differences being the DSP instructions and an
optional FPU. Only no-FPU cortex-M4 is implemented here, cortex-M4F
is not because the core target-arm code doesn't support the M-profile
FPU model yet.

exec: clamp accesses against the MemoryRegionSection
Because the clamping was done against the MemoryRegion,
address_space_rw was effectively broken if a write spanned
multiple sections that are not linear in underlying memory
(with the memory not being under an IOMMU).
This is visible with the MIPS rc4030 IOMMU, which is implemented
as a series of alias memory regions that point to the actual RAM.

exec: do not clamp accesses to MMIO regions
It is common for MMIO registers to overlap, for example a 4 byte register
at 0xcf8 (totally random choice... :)) and a 1 byte register at 0xcf9.
If these registers are implemented via separate MemoryRegions, it is
wrong to clamp the accesses as the value written would be truncated.
Hence for these regions the effects of commit 23820db (exec: Respect
as_translate_internal length clamp, 2015-03-16, previously applied as
commit c3c1bb99) must be skipped.

mc146818rtc: Reset the periodic timer on load
When loading a VM from a snapshot or migration, clock changes can cause
the periodic timer to stall or loop rapidly.
qemu-timer has a reset notifier mechanism that is used to avoid timer
stalls or loops if the host clock changes while the VM is running when
using QEMU_CLOCK_HOST. However, when loading a snapshot or migration,
qemu-timer is initialized and fires the reset notifier before
mc146818rtc is initialized and has registered its reset handler. In
addition, this mechanism isn't used when using QEMU_CLOCK_REALTIME,
which might also change when loading a snapshot or migration.
To correct that problem, this commit resets the periodic timer after
loading from a snapshot or migration if the clock has either jumped
backward or has jumped forward by more than the clock jump limit that
is used by the reset notifier code in qemu-timer.

qemu-timer: Call clock reset notifiers on forward jumps
Commit 691a0c9c introduced a mechanism by which QEMU_CLOCK_HOST can
notify other parts of the emulator when the host clock has jumped
backward. This is used to avoid stalling timers that were scheduled
based on the host clock.
However, if the host clock jumps forward, then timers that were
scheduled based on the host clock may fire rapidly and cause other
problems. For example, the mc146818rtc periodic timer will block
execution of the VM and consume host CPU while firing every interrupt
for the time period that was skipped by the host clock.
To correct that problem, this commit fires the reset notification if the
host clock jumps forward by more than a hard-coded limit. The limit is
currently set to a value of 60 seconds, which should be small enough to
prevent excessive timer loops, but large enough to avoid frequent resets
in idle VMs.

vhost: enable vhost without without MSI-X
We use vhostforce to enable vhost even if Guests don't have MSI-X
support and we fall back to QEMU virtio-net.
This gives a very small performance gain, but the disadvantage
is that guest now controls which virtio code is running
(qemu or vhost) so our attack surface is doubled.
This patch will enable vhost unconditionally whenever it's requested.
For compatibility, enable vhost when vhostforce is set, as well.

pci: Don't register a specialized 'config_write' if default behavior is intended
Few devices have their specialized 'config_write' methods which simply
call 'pci_default_write_config' followed by a 'msix_write_config' or
'msi_write_config' calls, using exact same arguments.
This is unnecessary as 'pci_default_write_config' already invokes
'msi_write_config' and 'msix_write_config'.
Also, since 'pci_default_write_config' is the default 'config_write'
handler, we can simply avoid the registration of these specialized
versions.

translate-all: fix watchpoints if retranslation not possible
The tb_check_watchpoint function currently assumes that all memory
access is done either directly through the TCG code or through an
helper which knows its return address. This is obviously wrong as the
helpers use cpu_ldxx/stxx_data functions to access the memory.
Instead of aborting in that case, don't try to retranslate the code, but
assume that the CPU state (and especially the program counter) has been
saved before calling the helper. Then invalidate the TB based on this
address.

target-s390x: PER instruction-fetch event support
For the PER instruction-fetch, we can't use the QEMU breakpoint
infrastructure as it triggers for a single address and not a full
address range, and as it actually stop before the instruction and
not before.
We therefore call an helper with the just fetched instruction address,
which check if the address is within the PER address range. If it is
the case, an event is recorded and will be signaled through an
exception.
Note that we implement here the PER-3 behaviour, that is an invalid
opcode is not considered as an instruction fetch. Without PER-3 this
behavious is undefined.

target-s390x: basic PER event handling
This patch add basic support to generate PER exceptions. It adds two
fields to the cpu structure to record for the PER address and PER
code & ATMID values. When an exception is triggered and a PER event is
pending, the two PER values are copied to the lowcore area.
At the end of an instruction, an helper is checking for a possible
pending PER event and triggers an exception in that case. For that to
work with branches, we need to disable TB chaining when PER is
activated. Fortunately it's already in the TB flags.
Finally in case of a SERVICE CALL exception, we need to trigger the PER
exception immediately after.

mvc_fast_memmove is bypassing the softmmu functions, getting the
physical source and destination addresses using the mmu_translate
function and accessing the corresponding physical memory. This
prevents watchpoints to work correctly.
Instead use the tlb_vaddr_to_host function to get the host addresses
corresponding to the guest source and destination addresses through the
softmmu code and fallback to the byte level code in case the
corresponding address are not in the QEMU TLB or being examined through
a watchpoint. As a bonus it works even for area crossing pages by
splitting the are into chunks contained in a single page, bringing some
performances improvements. We can therefore remove the 8-byte
loads/stores method, as it is now quite unlikely to be used.
At the same time change the name of the function to fast_memmove as it's
not specific to mvc and use the same argument order as the C memmove
function.

target-s390x: wire up DIAG IPL in TCG mode
DIAG IPL is already implemented for KVM, but not wired from TCG. For
that change the format of the instruction so that we can get R1 and R3
numbers in addition to the function code.
The diag function can change plenty of things, including CC, so we
should enter with a static CC. Also it doesn't set the value of general
register 2 to 0 as in the current code. We also need to exit the CPU
loop after a reset, which means a new PSW.

linux-user: ioctl() command type is int
When executing a 64bit target chroot on 64bit host,
the ioctl() command can mismatch.
It seems the previous commit doesn't solve the problem in
my case:
9c6bf9c7 linux-user: Fix ioctl cmd type mismatch on 64-bit targets
For example, a ppc64 chroot on an x86_64 host:
bash-4.3# ls
Unsupported ioctl: cmd=0x80087467
Unsupported ioctl: cmd=0x802c7415
The origin of the problem is in syscall.c:do_ioctl().
static abi_long do_ioctl(int fd, abi_long cmd, abi_long arg)
In this case (ppc64) abi_long is long (on the x86_64), and
cmd = 0x0000000080087467
then
if (ie->target_cmd == cmd)
target_cmd is int, so target_cmd = 0x80087467
and to compare an int with a long, the sign is extended to 64bit,
so the comparison is:
if (0xffffffff80087467 == 0x0000000080087467)
which doesn't match whereas it should.
This patch uses int in the case of the target command type
instead of abi_long.

linux-user: use __get_user and __put_user in cmsg conversions
The target payloads in cmsg conversions may not have the alignment
required by the host. Using the get_user and put_user functions is
the easiest way to handle this and also do the byte-swapping we
require.
(Note that prior to this commit target_to_host_cmsg was incorrectly
using __put_user() rather than __get_user() for the SCM_CREDENTIALS
conversion, which meant it wasn't getting the benefit of the
misalignment handling.)

linux-user: Fix length handling in host_to_target_cmsg
The previous code for handling payload length when converting
cmsg structures from host to target had a number of problems:
* we required the msg->msg_controllen to declare the buffer
to have enough space for final trailing padding (we were
checking against CMSG_SPACE), whereas the kernel does not
require this, and common userspace code assumes this. (In
particular, glibc's "try to talk to nscd" code that it will
run on startup will receive a cmsg with a 4 byte payload and
only allocate 4 bytes for it, which was causing us to do
the wrong thing on architectures that need 8-alignment.)
* we weren't correctly handling the fact that the SO_TIMESTAMP
payload may be larger for the target than the host
* we weren't marking the messages with MSG_CTRUNC when we did
need to truncate a message that wasn't truncated by the host,
but were instead logging a QEMU message; since truncation is
always the result of a guest giving us an insufficiently
sized buffer, we should report it to the guest as the kernel
does and don't log anything
Rewrite the parts of the function that deal with length to
fix these issues, and add a comment in target_to_host_cmsg
to explain why the overflow logging it does is a QEMU bug,
not a guest issue.

target-arm: Correct "preferred return address" for cpreg access exceptions
The architecture defines that when taking an exception trying to
access a coprocessor register, the "preferred return address" for
the exception is the address of the instruction that caused the
exception. Correct an off-by-4 error which meant we were returning
the address after the instruction for traps which happened because
of a failure of a runtime access-check function on an AArch32
register. (Traps caused by translate-time checkable permissions
failures had the correct address, as did traps on AArch64 registers.)

hw/arm/boot: fix rom_reset notifier registration order
commit ac9d32e39664e060cd1b538ff190980d57ad69e4 had the consequence to
register the do_cpu_reset after the rom_reset one. Hence they get
executed in the wrong order. This commit restores the registration of
do_cpu_reset in arm_load_kernel.

arm: Add has-mpu property
For processors that support MPUs, add a property to de-feature it. This
is similar to the implementation of the EL3 feature.
The processor definition in init sets ARM_FEATURE_MPU if it can support
an MPU. post_init exposes the property, defaulting to true. If cleared
by the instantiator, ARM_FEATURE_MPU is then removed at realize time.
This is to support R profile processors that may or may-not have an MPU
configured.

target-arm: Handle "extended small page" descriptors correctly
The old ARMv5-style page table format includes a kind of second level
descriptor named the "extended small page" format, whose primary purpose
is to allow specification of the TEX memory attribute bits on a 4K page.
This exists on ARMv6 and also (as an implementation extension) on XScale
CPUs; it's UNPREDICTABLE on v5.
We were mishandling this in two ways:
(1) we weren't implementing it for v6 (probably never noticed because
Linux will use the new-style v6 page table format there)
(2) we were not correctly setting the page_size, which is 4K, not 1K
The latter bug went unnoticed for years because the only thing which
the page_size affects is which TLB entries get flushed when the guest
does a TLB invalidate on an address in the page, and prior to commit
2f0d8631b7 we were doing a full TLB flush very frequently due to Linux's
habit of writing the SCTLR pointlessly a lot.
(We can assume that after commit 2f0d8631b7 the bug went unnoticed
for a year because nobody's actually using the Zaurus/XScale emulation...)
Report the correct page size for these descriptors, and permit them
on ARMv6 CPUs. This fixes a problem where a kernel image for Zaurus
can boot the kernel OK but gets random segfaults when it tries to
run userspace programs.

s390/bios: build with -fdelete-null-pointer-checks
Starting with version 4.9, GCC assumes it can't safely dereference null
pointers, and uses this for some optimizations. On s390, the lowcore
memory is located at address 0, so this assumption is wrong and breaks
the s390-ccw firmware. Pass -fdelete-null-pointer-checks to avoid that.

dsoundaudio: remove primary buffer
Enabling this option just creates a playback buffer with the specified settings,
and then ignores it. It's probably some outdated hack to set audio formats on
windows. (The first created stream dictates all other streams settings, at least
on some Windows versions). Setting DAC_FIXED_SETTINGS should have the same
effect as setting (the now removed) primary buffer.

linux-user: Allocate thunk size dynamically
We store all struct types in an array of static size without ever
checking whether we overrun it. Of course some day someone (like me
in another, ancient ALSA enabling patch set) will run into the limit
without realizing it.
So let's make the allocation dynamic. We already know the number of
structs that we want to allocate, so we only need to pass the variable
into the respective piece of code.
Also, to ensure we don't accidently overwrite random memory, add some
asserts to sanity check whether a thunk is actually part of our array.

block: Fix reopen flag inheritance
When reopening an image, the block layer already takes care to reopen
bs->file as well with recalculated inherited flags. The same must happen
for any other child (most notably missing before this patch: backing
files).
If bs->file (or any other child) didn't originally inherit from bs, e.g.
because it was created separately and then only referenced, it must not
inherit flags on reopen either, so check the inherited_from field before
propagation the reopen down.
VMDK already reopened its extents manually; this code can now be
dropped.

block: Add BlockDriverState.inherits_from
Currently, the block layer assumes that any block node can have only one
parent, and if it has a parent, that it inherits some options/flags from
this parent.
This is not true any more: With references used in block device
creation, a single node can be used by multiple parents, or it can be
created separately and not inherit flags from any parent.
To handle reopens correctly, a node must know from which parent it
inherited options. This patch adds the information to BlockDriverState.

block: Add list of children to BlockDriverState
This allows iterating over all children of a given BDS, not only
including bs->file and bs->backing_hd, but also driver-specific
ones like VMDK extents or Quorum children.
For bdrv_swap(), the list of children of the swapped BDS stays at that
BDS (because that's where the pointers stay as well). The list head
moves and pointers to it must be fixed up therefore.
The list of children in the parent of the swapped BDS is not affected by
the swap. The contents of the BDS objects is swapped, so the existing
pointer in the parent automatically points to the newly swapped in BDS.

block: Drain requests before swapping nodes in bdrv_swap()
bdrv_swap() requires that there are no requests in flight on either of
the two devices. The request coroutine would work on the wrong
BlockDriverState object (with bs->opaque even being interpreted as a
different type potentially) and all sorts of bad things would result
from this.
The currently existing callers mostly ensure that there is no I/O
pending on nodes that are swapped. In detail, this is:
1. Live snapshots. This goes through qmp_transaction(), which calls
bdrv_drain_all() before doing anything. The command is executed
synchronously, so no new I/O can be issued concurrently.
2. snapshot=on in bdrv_open(). We're in the middle of opening the image
(both the original image and its temporary overlay), so there can't
be any I/O in flight yet.
3. Mirroring. bdrv_drain() is already used on the source device so that
the mirror doesn't miss anything. However, the main loop runs between
that and the bdrv_swap() (which is actually a bug, being addressed in
another series), so there is a small window in which new I/O might be
issued that would be in flight during bdrv_swap().
It is safer to just drain the request queue of both devices in
bdrv_swap() instead of relying on callers to do the right thing.

qdict: Add qdict_{set,copy}_default()
In the block layer functions that determine options for a child block
device, it's a common pattern to either copy options from the parent's
options or to set a default string if the option isn't explicitly set
yet for the child. Provide convenience functions so that it becomes a
one-liner for each option.

qdict: Add qdict_array_entries()
This counts the entries in a flattened array in a QDict without
actually splitting the QDict into a QList.
bdrv_open_image() doesn't take a QList, but rather a QDict and a key
prefix string, so this is more convenient for block drivers which have a
dynamically sized list of child nodes (e.g. Quorum) and are to be
converted to using bdrv_open_image() as the standard interface for
opening child nodes.

iotests: Add tests for overriding BDRV_O_PROTOCOL
This adds tests for overriding the qemu-internal BDRV_O_PROTOCOL flag by
explicitly specifying a block driver. As one test must be run over the
NBD protocol while the other must not, this patch adds two separate

block: driver should override flags in bdrv_open()
The BDRV_O_PROTOCOL flag should have an impact only if no driver is
specified explicitly. Therefore, if bdrv_open() is called with an
explicit block driver argument (either through the options QDict or
through the drv parameter) and that block driver is a protocol block
driver, BDRV_O_PROTOCOL should be set; if it is a format block driver,
BDRV_O_PROTOCOL should be unset.
While there was code to unset the flag in case a format block driver
has been selected, it only followed the bdrv_fill_options() function
call whereas the flag in fact needs to be adjusted before it is used
there.
With that change, BDRV_O_PROTOCOL will always be set if the BDS should
be a protocol driver; if the driver has been specified explicitly, the
new code will set it; and bdrv_fill_options() will only "probe" a
protocol driver if BDRV_O_PROTOCOL is set. The probing after
bdrv_fill_options() cannot select a protocol driver.
Thus, bdrv_open_image() to open BDS.file is never called if a protocol
BDS is about to be created. With that change in turn it is impossible to
call bdrv_open_common() with a protocol drv and file != NULL, which
allows us to remove the bdrv_swap() call.
This change breaks a test case in qemu-iotest 051:
"-drive file=t.qcow2,file.driver=qcow2" now works because the explicitly
specified "qcow2" overrides the BDRV_O_PROTOCOL which is automatically
set for the "file" BDS (and the filename is just passed down).
Therefore, this patch removes that test case.

block: Change bitmap truncate conditional to assertion
This is an artifact of an older version that had both all-bitmap and
single-bitmap truncate functions, and some info got lost in the shuffle.
Bitmaps can only be frozen during a backup operation, and a backup
operation should prevent a resize operation, so just assert that this
cannot happen.

qcow2: Add DEFAULT_L2_CACHE_CLUSTERS
If a relatively large cluster size is chosen, the default of 1 MB L2
cache is not really appropriate. In this case, unless overridden by the
user, the default cache size should not be determined by its size in
bytes but by the number of L2 tables (clusters) it is supposed to
contain.
Note that without this patch, MIN_L2_CACHE_SIZE will effectively take
over the same role. However, providing space for just two L2 tables is
not enough to be the default.

The throttle group support use a cooperative round robin scheduling

The principles of the algorithm are simple:
- Each BDS of the group is used as a token in a circular way.
- The active BDS computes if a wait must be done and arms the right
timer.
- If a wait must be done the token timer will be armed so the token
will become the next active BDS.

rocker: bring link up/down on PHY enable/disable
When the OS driver enables/disables the port, go ahead and set the port's
link status to up/down in response to the change. This more closely
emulates real hardware when the PHY for the port is brought up/down
and the PHY negotiates carrier (link status) with link partner. In
the case of qemu, the virtual rocker device can't really do link
negotiation with the link partner as that requires signally over a
physical medium (the wire), so just pretend the negotiation was
successful and bring the link up when the port is enabled.

virtio-gpu-pci: add virtio pci support
This patch adds virtio-gpu-pci, which is the pci proxy for the virtio
gpu device. With this patch in place virtio-gpu is functional. You
need a linux guest with a virtio-gpu driver though, and output will
appear pretty late in boot, once the kernel initialized drm and fbcon.

target-mips: add MTHC0 and MFHC0 instructions
Implement MTHC0 and MFHC0 instructions. In MIPS32 they are used to access
upper word of extended to 64-bits CP0 registers.
In MIPS64, when CP0 destination register specified is the EntryLo0 or
EntryLo1, bits 1:0 of the GPR appear at bits 31:30 of EntryLo0 or
EntryLo1. This is to compensate for RI and XI, which were shifted to bits
63:62 by MTC0 to EntryLo0 or EntryLo1. Therefore creating separate
functions for EntryLo0 and EntryLo1.

target-mips: add CP0.PageGrain.ELPA support
CP0.PageGrain.ELPA enables support for large physical addresses. This field
is encoded as follows:
0: Large physical address support is disabled.
1: Large physical address support is enabled.
If this bit is a 1, the following changes occur to coprocessor 0 registers:
- The PFNX field of the EntryLo0 and EntryLo1 registers is writable and
concatenated with the PFN field to form the full page frame number.
- Access to optional COP0 registers with PA extension, LLAddr, TagLo is
defined.
P5600 can operate in 32-bit or 40-bit Physical Address Mode. Therefore if
XPA is disabled (CP0.PageGrain.ELPA = 0) then assume 32-bit Address Mode.
In MIPS64 assume 36 as default PABITS (when CP0.PageGrain.ELPA = 0).
env->PABITS value is constant and indicates maximum PABITS available on
a core, whereas env->PAMask is calculated from env->PABITS and is also
affected by CP0.PageGrain.ELPA.

Add a protective section footer
Badly formatted migration streams can go undetected or produce
misleading errors due to a lock of checking at the end of sections.
In particular a section that adds an extra 0x00 at the end
causes what looks like a normal end of stream and thus doesn't produce
any errors, and something that ends in a 0x01..0x04 kind of look
like real section headers and then fail when the section parser tries
to figure out which section they are. This is made worse by the
choice of 0x00..0x04 being small numbers that are particularly common
in normal section data.
This patch adds a section footer consisting of a marker (0x7e - ~)
followed by the section-id that was also sent in the header. If
they mismatch then it throws an error explaining which section was
being loaded.

i386/acpi-build: fix PXB workarounds for unsupported BIOSes
The patch
apci: fix PXB behaviour if used with unsupported BIOS
uses the following condition to see if a "PXB mem/IO chunk" has *not* been
configured by the BIOS:
(!range_base || range_base > range_limit)
When this condition evaluates to true, said patch *omits* the
corresponding entry from the _CRS.
Later on the patch checks for the opposite condition (with the intent of
*adding* entries to the _CRS if the "PXB mem/IO chunks" *have* been
configured). Unfortunately, the condition was negated incorrectly: only
the first ! operator was removed, which led to the nonsensical expression
(range_base || range_base > range_limit)
leading to bogus entries in the _CRS, and causing BSOD in Windows Server
2012 R2 when it runs on OVMF.
The correct negative of the condition seen at the top is
(range_base && range_base <= range_limit)
Fix the expressions.

i386/acpi-build: more traditional _UID and _HID for PXB root buses
The ACPI specification permits the _HID and _UID objects to evaluate to
strings. (See "6.1.5 _HID (Hardware ID)" and "6.1.12 _UID (Unique ID)" in
the ACPI v6.0 spec.)
With regard to related standards, the UEFI specification can also express
a device address composed from string _HID and _UID identifiers, inside
the Expanded ACPI Device Path Node. (See "9.3.3 ACPI Device Path", Table
49, in the UEFI v2.5 spec.)
However, numeric (integer) contents for both _HID and _UID are more
traditional. They are recommended by the UEFI spec for size reasons:
[...] the ACPI Device Path node is smaller and should be used if
possible to reduce the size of device paths that may potentially be
stored in nonvolatile storage [...]
External tools support them better (for example the --acpi_hid and
--acpi_uid options of "efibootmgr" only take numeric identifiers).
Finally, numeric _HID and _UID contents are existing practice in the QEMU
source.
This patch was tested with a Fedora 20 LiveCD and a preexistent Windows
Server 2012 R2 guest. Using "acpidump" and "iasl" in the Fedora guest, we
get, in the SSDT:
> Scope (\_SB)
> {
> Device (PC04)
> {
> Name (_UID, 0x04) // _UID: Unique ID
> Name (_HID, EisaId ("PNP0A03") /* PCI Bus */) // _HID: Hardware ID

support for using over 256MB of RAM with the MIPS Malta board, including
capping the memsize variable that QEMUs pseudo-bootloader provides to
the kernel at 256MB in order to match YAMON. It didn't however provide
the ememsize variable which kernels supporting memory outside of the
unmapped address spaces (ie. EVA or highmem) may use to determine the
true size of the RAM present in the system.
Set ememsize to the size of RAM so that such kernels may use all
available memory without the user having to manually specifying its size
& location.

This patch adds virtio-pci support for the emulated virtio-input

to your command line. If you want add multiple devices but don't want
waste a pci slot for each you can compose a multifunction device this way:
qemu -device virtio-keyboard-pci,addr=0d.0,multifunction=on \
-device virtio-tablet-pci,addr=0d.1,multifunction=on

virtio-pci: correctly set host notifiers for modern bar
Currently, during host notifier set. We only add eventfd for legacy
bar, this is not correct since:
- Non-transitional device does not have legacy bar, so qemu will crash
since proxy->bar was not initialized.
- Modern device uses modern bar and notify cap to notify the device,
we should add eventfd for proxy->notify.
So this patch fixes the above two issues by adding eventfd based on
whether legacy or modern device were supported.

pcnet: force the buffer access to be in bounds during tx
4096 is the maximum length per TMD and it is also currently the size of
the relay buffer pcnet driver uses for sending the packet data to QEMU
for further processing. With packet spanning multiple TMDs it can
happen that the overall packet size will be bigger than sizeof(buffer),
which results in memory corruption.
Fix this by only allowing to queue maximum sizeof(buffer) bytes.
This is CVE-2015-3209.

bios-tables-test: handle false-positive smbios signature matches
It has been reported that sometimes the .rodata section of SeaBIOS,
containing the constant string against which the SMBIOS signature
ends up being compared, also falls within the guest f-segment. In
that case, the test obviously fails, unless we continue searching
for the *real* SMBIOS entry point.
Rather than stopping at the first match for the SMBIOS signature
("_SM_") in the f-segment (0xF0000-0xFFFFF), continue scanning
until either a valid entry point table is found, or the f-segment
has been exhausted.

tcg: fix dead computation for repeated input arguments
When the same temp is used twice or more as an input argument to a TCG
instruction, the dead computation code doesn't recognize the second use
as a dead temp. This is because the temp is marked as live in the same
loop where dead inputs are checked.
The fix is to split the loop in two parts. This avoid emitting a move
and using a register for the movcond instruction when used as "move if
true" on x86-64. This might bring more improvements on RISC TCG targets
which don't have outputs aliased to inputs.

tcg: fix register allocation with two aliased dead inputs
For TCG ops with two outputs registers (add2, sub2, div2, div2u), when
the same input temp is used for the two inputs aliased to the two
outputs, and when these inputs are both dead, the register allocation
code wrongly assigned the same register to the same output.
This happens for example with sub2 t1, t2, t3, t3, t4, t5, when t3 is
not used anymore after the TCG op. In that case the same register is
used for t1, t2 and t3.
The fix is to look for already allocated aliased input when allocating
a dead aliased input and check that the register is not already
used.

it's destroyed, but trying to call SDL_GetWindowFromID() from that
event's window ID returns a null pointer. handle_windowevent() assumes
that the pointer is never null so it results in a crash.

vhost-user: Improve -netdev/netdev_add/-net/... error reporting
When -netdev vhost-user fails, it first reports a specific error, then
one or more generic ones, like this:
$ qemu-system-x86_64 -netdev vhost-user,id=foo,chardev=xxx
qemu-system-x86_64: -netdev vhost-user,id=foo,chardev=xxx: chardev "xxx" not found
qemu-system-x86_64: -netdev vhost-user,id=foo,chardev=xxx: No suitable chardev found
qemu-system-x86_64: -netdev vhost-user,id=foo,chardev=xxx: Device 'vhost-user' could not be initialized
With the command line, the messages go to stderr. In HMP, they go to
the monitor. In QMP, the last one becomes the error reply, and the
others go to stderr.
Convert net_init_vhost_user() and its helpers to Error. This
suppresses the unwanted unspecific error messages, and makes the
specific error the QMP error reply.

When the argument is non-zero, qemu_opt_foreach() stops on callback

vl: Fail right after first bad -object
Failure to create an object with -object is a fatal error. However,
we delay the actual exit until all -object are processed. On the one
hand, this permits detection of genuine additional errors. On the
other hand, it can muddy the waters with uninteresting additional
errors, e.g. when a later -object tries to reference a prior one that
failed.
We generally stop right on the first bad option, so do that for
-object as well.

machine: Drop use of DEFAULT_RAM_SIZE in help text
As of commit 076b35b5a (machine: add default_ram_size to machine
class) we no longer have a global default ram size, but instead
machine specific defaults. When invoking qemu --help we don't know
which machine you selected, so we can't tell the user the default RAM
size in the help text anymore now.
Thus I don't see an easy way to expose the default ram size to the
user in the help text. The easiest option IMHO is to just drop this
piece of information.

atomics: add explicit compiler fence in __atomic memory barriers
__atomic_thread_fence does not include a compiler barrier; in the
C++11 memory model, fences take effect in combination with other
atomic operations. GCC implements this by making __atomic_load and
__atomic_store access memory as if the pointer was volatile, and
leaves no trace whatsoever of acquire and release fences in the
compiler's intermediate representation.
In QEMU, we want memory barriers to act on all memory, but at the same
time we would like to use __atomic_thread_fence for portability reasons.
Add compiler barriers manually around the __atomic_thread_fence.

hw/i386: add a separate region that tracks the SMRAME bit
This region is exported at /machine/smram. It is "empty" if
SMRAME=0 and points to SMRAM if SMRAME=1. The CPU will
enable/disable it as it enters or exits SMRAM.
While touching nearby code, the existing memory region setup was
slightly inconsistent. The smram_region is *disabled* in order to open
SMRAM (because the smram_region shows the low VRAM instead of the RAM
at 0xa0000). Because SMRAM is closed at startup, the smram_region must
be enabled when creating the i440fx or q35 devices.

vl: allow full-blown QemuOpts syntax for -global
-global does not work for drivers that have a dot in their name, such as
cfi.pflash01. This is just a parsing limitation, because such globals
can be declared easily inside a -readconfig file.
To allow this usage, support the full QemuOpts key/value syntax for -global
too, for example "-global driver=cfi.pflash01,property=secure,value=on".
The two formats do not conflict, because the key/value syntax does not have
a period before the first equal sign.

target-i386: mask NMIs on entry to SMM
QEMU is not blocking NMIs on entry to SMM. Implementing this has to
cover a few corner cases, because:
- NMIs can then be enabled by an IRET instruction and there
is no mechanism to _set_ the "NMIs masked" flag on exit from SMM:
"A special case can occur if an SMI handler nests inside an NMI handler
and then another NMI occurs. [...] When the processor enters SMM while
executing an NMI handler, the processor saves the SMRAM state save map
but does not save the attribute to keep NMI interrupts disabled.
- However, there is some hidden state, because "If NMIs were blocked
before the SMI occurred [and no IRET is executed while in SMM], they
are blocked after execution of RSM." This is represented by the new
HF2_SMM_INSIDE_NMI_MASK bit. If it is zero, NMIs are _unblocked_
on exit from RSM.

While it is obvious that cpu_physical_memory_get_dirty returns true even if

one would expect that it returns true only if all the pages are clean, but
it actually looks for even one clean page. (By contrast, the caller of that

To clarify, rename the function to cpu_physical_memory_all_dirty and return
true if _all_ the pages are dirty. This is the opposite of the previous
meaning, because "all are 1" is the same as "not (any is 0)", so we have to

translate-all: make less of tb_invalidate_phys_page_range depend on is_cpu_write_access
is_cpu_write_access is only set if tb_invalidate_phys_page_range is called
from tb_invalidate_phys_page_fast, and hence from notdirty_mem_write.
However:
- the code bitmap can be built directly in tb_invalidate_phys_page_fast
(unconditionally, since is_cpu_write_access would always be passed as 1);
- the virtual address is not needed to mark the page as "not containing
code" (dirty code bitmap = 1), so we can also remove that use of
is_cpu_write_access. For calls of tb_invalidate_phys_page_range
that do not come from notdirty_mem_write, the next call to
notdirty_mem_write will notice that the page does not contain code
anymore, and will fix up the TLB entry.
The parameter needs to remain in order to guard accesses to cpu->mem_io_pc.

exec: use memory_region_get_dirty_log_mask to optimize dirty tracking
The memory API can now return the exact set of bitmaps that have to
be tracked. Use it instead of the in_migration variable.
In the next patches, we will also use it to set only DIRTY_MEMORY_VGA
or DIRTY_MEMORY_MIGRATION if necessary. This can make a difference
for dataplane, especially after the dirty bitmap is changed to use
more expensive atomic operations.
Of some interest is the change to stl_phys_notdirty. When migration
was introduced, stl_phys_notdirty was changed to effectively behave
as stl_phys during migration. In fact, if one looks at the function as it
was in the beginning (commit 8df1cd0, physical memory access functions,
2005-01-28), at the time the dirty bitmap was the equivalent of
DIRTY_MEMORY_CODE nowadays; hence, the function simply should not touch
the dirty code bits. This patch changes it to do the intended thing.

memory: include DIRTY_MEMORY_MIGRATION in the dirty log mask
The separate handling of DIRTY_MEMORY_MIGRATION, which does not
call log_start/log_stop callbacks when it changes in a region's
dirty logging mask, has caused several bugs.
One recent example is commit 4cc856f (kvm-all: Sync dirty-bitmap from
kvm before kvm destroy the corresponding dirty_bitmap, 2015-04-02).
Another performance problem is that KVM keeps tracking dirty pages
after a failed live migration, which causes bad performance due to
disallowing huge page mapping.
This patch removes the root cause of the problem by reporting
DIRTY_MEMORY_MIGRATION changes via log_start and log_stop.
Note that we now have to rebuild the FlatView when global dirty
logging is enabled or disabled; this ensures that log_start and
log_stop callbacks are invoked.
This will also be used to make the setting of bitmaps conditional.
In general, this patch lets users of the memory API ignore the
global state of dirty logging if they handle dirty logging
generically per region.

enable/disable logging by itself.
We could always treat updates as invalidations if dirty logging is
not enabled, assuming that the board will enable logging on the
RAM region that includes the framebuffer.
However, the function is unused, so just drop it.

memory: prepare for multiple bits in the dirty log mask
When the dirty log mask will also cover other bits than DIRTY_MEMORY_VGA,
some listeners may be interested in the overall zero/non-zero value of
the dirty log mask; others may be interested in the value of single bits.
For this reason, always call log_start/log_stop if bits have respectively
appeared or disappeared, and pass the old and new values of the dirty log
mask so that listeners can distinguish the kinds of change.
For example, KVM checks if dirty logging used to be completely disabled
(in log_start) or is now completely disabled (in log_stop). On the
other hand, Xen has to check manually if DIRTY_MEMORY_VGA changed,
since that is the only bit it cares about.

memory: differentiate memory_region_is_logging and memory_region_get_dirty_log_mask
For now memory regions only track DIRTY_MEMORY_VGA individually, but
this will change soon. To support this, split memory_region_is_logging
in two functions: one that returns a given bit from dirty_log_mask,
and one that returns the entire mask. memory_region_is_logging gets an
extra parameter so that the compiler flags misuse.
While VGA-specific users (including the Xen listener!) will want to keep
checking that bit, KVM and vhost check for "any bit except migration"
(because migration is handled via the global start/stop listener
callbacks).

Makefile.target: set master BUILD_DIR
make can be invoked in the individual build dirs to build an individual
target or just a single file of a target. e.g.
touch translate-all.c
make -C microblazeel-softmmu translate-all.o
There is however a small bug when using the pixman submodule.
config-host.mak will ref BUILD_DIR for the pixman -I CFLAGS:
grep BUILD_DIR config-host.mak
QEMU_CFLAGS=-I$(SRC_PATH)/pixman/pixman -I$(BUILD_DIR)/pixman/pixman ...
This causes a build failure as -I/pixman/pixman (BUILD_DIR=="") will
not be found.
BUILD_DIR is usually set by the top level Makefile. Just lazy-set it in
Makefile.target to the parent directory.
Granted, this will not work if the pixman submodule is not prebuilt,
but it at least means you can do incremental partial builds once you
have done your initial full build (or attempt) from the top level.
The next step would be refactor make infrastructure to rebuild pixman
on a submake like the one above.

exec: optimize phys_page_set_level
phys_page_set_level is writing zeroes to a struct that has just been
filled in by phys_map_node_alloc. Instead, tell phys_map_node_alloc
whether to fill in the page "as a leaf" or "as a non-leaf".
memcpy is faster than struct assignment, which copies each bitfield
individually. A compiler bug (https://gcc.gnu.org/PR66391), and
small memcpys like this one are special-cased anyway, and optimized
to a register move, so just use the memcpy.
This cuts the cost of phys_page_set_level from 25% to 5% when
booting qboot.

ppc: add helpful message when KVM fails to start VCPU
On POWER8 systems, KVM checks if VCPU is running on primary threads,
and that secondary threads are offline. If this is not the case,
ioctl() fails with errno set to EBUSY.
QEMU aborts with a non explicit error message:
$ ./qemu-system-ppc64 --nographic -machine pseries,accel=kvm
error: kvm run failed Device or resource busy
To help user to diagnose the problem, this patch adds an informative
error message.
There is no easy way to check if SMT is enabled before starting the VCPU,
and as this case is the only one setting errno to EBUSY, we just check
the errno value to display a message.

target-s390x: fix MVC instruction when areas overlap
The MVC instruction and the memmove C funtion do not have the same
semantic when memory areas overlap:
MVC: When the operands overlap, the result is obtained as if the
operands were processed one byte at a time and each result byte were
stored immediately after fetching the necessary operand byte.
memmove: Copying takes place as though the bytes in src are first copied
into a temporary array that does not overlap src or dest, and the bytes
are then copied from the temporary array to dest.
The behaviour is therefore the same when the destination is at a lower
address than the source, but not in the other case. This is actually a
trick for propagating a value to an area. While the current code detects
that and call memset in that case, it only does for 1-byte value. This
trick can and is used for propagating two or more bytes to an area.
In the softmmu case, the call to mvc_fast_memmove is correct as the
above tests verify that source and destination are each within a page,
and both in a different page. The part doing the move 8 bytes by 8 bytes
is wrong and we need to check that if the source and destination
overlap, they do with a distance of minimum 8 bytes before copying 8
bytes at a time.
In the user code, we should check check that the destination is at a
lower address than source or than the end of the source is at a lower
address than the destination before calling memmove. In the opposite
case we fallback to the same code as the softmmu one. Note that l
represents (length - 1).

target-s390x: use softmmu functions for mvcp/mvcs
mvcp and mvcs helper get access to the physical memory by a call to
mmu_translate for the virtual to real conversion and then using ldb_phys
and stb_phys to physically access the data. In practice this is quite
slow because it bypasses the QEMU softmmu TLB and because stb_phys calls
try to invalidate the corresponding memory for each access.
Instead use cpu_ldb_{primary,secondary} for the loads and
cpu_stb_{primary,secondary} for the stores. Ideally this should be
further optimized by a call to memcpy, but that already improves the
boot time of a guest by a factor 1.8.

target-s390x: change CHRL and CGHRL format to RIL-b
Change to match the PoP. In practice both format RIL-a and RIL-b have
the same fields. They differ on the way we decode the fields, and it's
done correctly in QEMU.

target-s390x: fix exception for invalid operation code
When an operation code is not recognized (ie invalid instruction) an
operation exception should be generated instead of a specification
exception. The latter is for valid opcode, with invalid operands or
modifiers.
This give a very basic GDB support in the guest, as it uses the invalid
opcode 0x0001 to generate a trap.

target-s390x: fix MMU index computation
The cpu_mmu_index function wrongly looks at PSW P bit to determine the
MMU index, while this bit actually only control the use of priviledge
instructions. The addressing mode is detected by looking at the PSW ASC
bits instead.
This used to work more or less correctly up to kernel 3.6 as the kernel
was running in primary space and userland in secondary space. Since
kernel 3.7 the default is to run the kernel in home space and userland
in primary space. While the current QEMU code seems to work it open some
security issues, like accessing the lowcore memory in R/W mode from a
userspace process once it has been accessed by the kernel (it is then
cached by the QEMU TLB).
At the same time change the MMU_USER_IDX value so that it matches the
value used in recent kernels.

target-s390x: fix LOAD MULTIPLE instruction on page boundary
When consecutive memory locations are on page boundary a page fault
might occur when using the LOAD MULTIPLE instruction. In that case real
hardware doesn't load any register.
This is an important detail in case the base register is in the list
of registers to be loaded. If a page fault occurs this register might be
overwritten and when the instruction is later restarted the wrong
base register value is useD.
Fix this by first loading the first and last value from memory, hence
triggering all possible page faults, and then the remaining registers.
This fixes random segmentation faults seen in the guest.

vhost: logs sharing
Currently we allocate one vhost log per vhost device. This is sub
optimal when:
- Guest has several device with vhost as backend
- Guest has multiqueue devices
In the above cases, we can avoid the memory allocation by sharing a
single vhost log among all the vhost devices. This is done through:
- Introducing a new vhost_log structure with refcnt inside.
- Using a global pointer to vhost_log structure that will be used. And
introduce helper to get the log with expected log size and helper to
- drop the refcnt to the old log.
- Each vhost device still keep track of a pointer to the log that was
used.
With above, if no resize happens, all vhost device will share a single
vhost log. During resize, a new vhost_log structure will be allocated
and made for the global pointer. And each vhost devices will drop the
refcnt to the old log.
Tested by doing scp during migration for a 2 queues virtio-net-pci.

hw/acpi: piix4_pm_init(): take fw_cfg object no more
This PIIX4 init function has no more reason to receive a pointer to the
FwCfg object. Remove the parameter from the prototype, and update callers.
As a result, the pc_init1() function no longer needs to save the return
value of pc_memory_init() and xen_load_linux(), which makes it more
similar to pc_q35_init().
The return type & value of pc_memory_init() and xen_load_linux() are not
changed themselves; maybe we'll need their return values sometime later.

hw/acpi: move "etc/system-states" fw_cfg file from PIIX4 to core
The acpi_pm1_cnt_init() core function is responsible for setting up the
register block that will ultimately react to S3 and S4 requests (see
acpi_pm1_cnt_write()). It makes sense to advertise this configuration to
the guest firmware via an easy to parse fw_cfg file (ACPI is too complex
for firmware to parse), and indeed PIIX4 does that. However, since
acpi_pm1_cnt_init() is not specific to PIIX4, neither should be the fw_cfg
file.
This patch makes "etc/system-states" appear on all chipsets modified in
the previous patch, not just PIIX4 (assuming they have fw_cfg at all).

hw/acpi: acpi_pm1_cnt_init(): take "disable_s3" and "disable_s4"
This patch only modifies the function prototype and updates all chipset
code that calls acpi_pm1_cnt_init() to pass in their own disable_s3 and
disable_s4 settings. vt82c686 is assumed to be fixed "S3 and S4 enabled".

pc-dimm: don't assert if pc-dimm alignment != hotpluggable mem range size
Drop superfluous pc-dimm alignment on hot-pluggable mem
range size assert, since it causes QEMU crash during hotplug
when hotplugging pc-dimm with alignment bigger than
an alignment of hot-pluggable mem range size.
Instead allow pc_dimm_get_free_addr() find free address

pseries: Enable in-kernel H_LOGICAL_CI_{LOAD, STORE} implementations
qemu currently implements the hypercalls H_LOGICAL_CI_LOAD and
H_LOGICAL_CI_STORE as PAPR extensions. These are used by the SLOF firmware
for IO, because performing cache inhibited MMIO accesses with the MMU off
(real mode) is very awkward on POWER.
This approach breaks when SLOF needs to access IO devices implemented
within KVM instead of in qemu. The simplest example would be virtio-blk
using an iothread, because the iothread / dataplane mechanism relies on
an in-kernel implementation of the virtio queue notification MMIO.
To fix this, an in-kernel implementation of these hypercalls has been made,
(kernel commit 99342cf "kvmppc: Implement H_LOGICAL_CI_{LOAD,STORE} in KVM"
however, the hypercalls still need to be enabled from qemu. This performs
the necessary calls to do so.
It would be nice to provide some warning if we encounter a problematic
device with a kernel which doesn't support the new calls. Unfortunately,
I can't see a way to detect this case which won't either warn in far too
many cases that will probably work, or which is horribly invasive.

This function handles generation of ibm,drc-* array device tree

hotplug/unplug.
Since general management of boot-time device trees are handled
outside of sPAPRDRConnector, we insert these values blindly given
an FDT and offset. A mask of sPAPRDRConnector types is given to
instruct us on what types of connectors entries should be generated
for, since descriptions for different connectors may live in
different parts of the device tree.

spapr_events: event-scan RTAS interface
We don't actually rely on this interface to surface hotplug events, and
instead rely on the similar-but-interrupt-driven check-exception RTAS
interface used for EPOW events. However, the existence of this interface
is needed to ensure guest kernels initialize the event-reporting
interfaces which will in turn be used by userspace tools to handle these
events, so we implement this interface here.
Since events surfaced by this call are mutually exclusive to those
surfaced via check-exception, we also update the RTAS event queue code
to accept a boolean to mark/filter for events accordingly.
Events of this sort are not currently generated by QEMU, but the interface
has been tested by surfacing hotplug events via event-scan in place
of check-exception.

spapr_events: re-use EPOW event infrastructure for hotplug events
This extends the data structures currently used to report EPOW events to
guests via the check-exception RTAS interfaces to also include event types
for hotplug/unplug events.
This is currently undocumented and being finalized for inclusion in PAPR
specification, but we implement this here as an extension for guest
userspace tools to implement (existing guest kernels simply log these
events via a sysfs interface that's read by rtas_errd, and current
versions of rtas_errd/powerpc-utils already support the use of this
mechanism for initiating hotplug operations).
We also add support for queues of pending RTAS events, since in the
case of hotplug there's chance for multiple events being in-flight
at any point in time.

This interface is used to fetch an OF device-tree nodes that describes a

device-tree node and fetch individual properties into a 'workarea'/buffer

The device-tree is generated by QEMU and passed to an sPAPRDRConnector during
the initial hotplug operation, and the state of these RTAS calls is tracked by
the sPAPRDRConnector. When the last of these properties is successfully
fetched, we report as special return value to the guest and transition
the device to a 'configured' state on the QEMU/DRC side.

spapr_drc: initial implementation of sPAPRDRConnector device
This device emulates a firmware abstraction used by pSeries guests to
manage hotplug/dynamic-reconfiguration of host-bridges, PCI devices,
memory, and CPUs. It is conceptually similar to an SHPC device,
complete with LED indicators to identify individual slots to physical
physical users and indicate when it is safe to remove a device. In
some cases it is also used to manage virtualized resources, such a
memory, CPUs, and physical-host bridges, which in the case of pSeries
guests are virtualized resources where the physical components are
managed by the host.
Guests communicate with these DR Connectors using RTAS calls,
generally by addressing the unique DRC index associated with a
particular connector for a particular resource. For introspection
purposes we expose this state initially as QOM properties, and
in subsequent patches will introduce the RTAS calls that make use of
it. This constitutes to the 'guest' interface.
On the QEMU side we provide an attach/detach interface to associate
or cleanup a DeviceState with a particular sPAPRDRConnector in
response to hotplug/unplug, respectively. This constitutes the
'physical' interface to the DR Connector.

hw/ppc/spapr: Fix error message when firmware could not be loaded
When specifying a non-existing file with the "-bios" parameter, QEMU
complained that it "could not find LPAR rtas". That's obviously a
copy-n-paste bug from the code which loads the spapr-rtas.bin, it
should complain about a missing firmware file instead.
Additionally the error message was printed with hw_error() - which
also dumps the whole CPU state. However, this does not make much
sense here since the CPU is not running yet and thus the registers
only contain zeroes. So let's use error_report() here instead.
And while we're at it, let's also bail out if the firmware file
had zero length.

spapr_pci: Fix unsafe signed/unsigned comparisons
spapr_pci.c contains a number of expressions of the form (uval == -1) or
(uval != -1), where 'uval' is an unsigned value.
This mostly works in practice, because as long as the width of uval is
greater or equal than that of (int), the -1 will be promoted to the
unsigned type, which is the expected outcome.
However, at least for the cases where uval is uint32_t, this would break
on platforms where sizeof(int) > 4 (and a few such do exist), because then
the uint32_t value would be promoted to the larger int type, and never be
equal to -1.
This patch fixes these errors. The fixes for the (uint32_t) cases are
necessary as described above. I've made similar fixes to (uint64_t) and
(hwaddr) cases. Those are strictly theoretical, since I don't know of any
platforms where sizeof(int) > 8, but hey, it's not that hard so we might
as well be strictly C standard compliant.

hw/pci: introduce PCI Expander Bridge (PXB)
PXB is a "light-weight" host bridge whose purpose is to enable
the main host bridge to support multiple PCI root buses
for pc machines.
As oposed to PCI-2-PCI bridge's secondary bus, PXB's bus
is a primary bus and can be associated with a NUMA node
(different from the main host bridge) allowing the guest OS
to recognize the proximity of a pass-through device to
other resources as RAM and CPUs.
The PXB is composed from:
- A primary PCI bus (can be associated with a NUMA node)
Acts like a normal pci bus and from the functionality point
of view is an "expansion" of the bus behind the
main host bridge.
- A pci-2-pci bridge behind the primary PCI bus where the actual
devices will be attached.
- A host-bridge PCI device
Situated on the bus behind the main host bridge, allows
the BIOS to configure the bus number and IO/mem resources.
It does not have its own config/data register for configuration
cycles, this being handled by the main host bridge.
- A host-bridge sysbus to comply with QEMU current design.

virtio-pci: don't try to mask or unmask vqs without notifiers
We should validate the vq index against nvqs_with_notifiers. Otherwise we may
try to mask or unmask vector for vqs without notifiers (e.g control vq). This
will lead qemu abort on kvm_irqchip_commit_routes() when trying to boot win8.1
guest.

s390x/kvm: always ignore empty vcpu interrupt state
kvm_s390_vcpu_interrupt_pre_save() and
kvm_s390_vcpu_interrupt_post_load() are essentially no-ops on hosts
without KVM_CAP_S390_IRQ_STATE. Move the capability check after the
check for saved IRQ state in kvm_s390_vcpu_interrupt_post_load() so that
migration between hosts without KVM_CAP_S390_IRQ_STATE (including save /
restore on the same host) continues to work.

virtio-ccw/migration: Migrate config vector for virtio devices
virtio_ccw_{save|load}_config are missing code to save and restore a vdev's
config_vector value. This causes some virtio devices to become disabled
following a migration.
This patch fixes a bug whereby the qmp/hmp balloon command (virsh setmem)
silently fails to update the guest's available memory because the device was not
properly migrated.
This will break compatibility, but vmstate_s390_cpu was bumped from
version 2 to version 4 between v2.3.0 and v2.4.0 without a compat
handler. Furthermore, there is no production environment yet so
migration is fenced anyway between any relevant version of 2.3 and 2.4.

configure: postfix --extra-cflags to QEMU_CFLAGS
It makes sense that extra-cflags should be appended after the normal
CFLAGS so they don't get overridden by default behaviour. This way if
you specify something like:
./configure --extra-cflags="-O0"
You will see the requested behaviour.

While at it, reset the resulting directory name within smb structure

util: socket: Add missing localaddr and localport option for DGRAM socket
The 'socket_optslist' structure does not contain the 'localaddr' and
'localport' options that are parsed in case you are creating a
'connect' type UDP character device.
I've noticed it happening after commit f43e47dbf6de24db20ec9b588bb6cc762
made qemu abort() after seeing the invalid option.
A minimal reproducer for the case is:
$ qemu-system-x86_64 -chardev udp,id=charrng0,host=127.0.0.1,port=1234,localaddr=,localport=1234
qemu-system-x86_64: -chardev udp,id=charrng0,host=127.0.0.1,port=1234,localaddr=,localport=1234: Invalid parameter 'localaddr'
Aborted (core dumped)
Prior to the commit mentioned above the error would be printed but the
value for localaddr and localport was simply ignored. I did not go
through the code to find out when it was broken.
Add the two fields so that the options can again be parsed correctly and
qemu doesn't abort().

pc: Ensure non-zero CPU ref count after attaching to ICC bus
Setting the parent bus of a device increases its ref count, which we
ultimately want to level out. However it is only safe to do so after the
last reference to the device in local code, as qom-set or similar operations
might decrease the ref count.
Therefore move the object_unref() from pc_new_cpu() into its callers.
The APIC operations on the last CPU in pc_cpus_init() are still potentially
insecure, but that is beyond the scope of this code movement.

fdc: Fix MSR.RQM flag
The RQM bit in MSR should be set whenever the guest is supposed to
access the FIFO, and it should be cleared in all other cases. This is
important so the guest can't continue writing/reading the FIFO beyond
the length that it's suppossed to access (see CVE-2015-3456).
Commit e9077462 fixed the CVE by adding code that avoids the buffer
overflow; however it doesn't correct the wrong behaviour of the floppy
controller which should already have cleared RQM.
Currently, RQM stays set all the time and during all phases while a
command is being processed. This is error-prone because the command has
to explicitly clear the flag if it doesn't need data (and indeed, the
two buggy commands that are the culprits for the CVE just forgot to do
that).
This patch clears RQM immediately as soon as all bytes that are expected
have been received. If the the FIFO is used in the next phase, the flag
has to be set explicitly there.
It also clear RQM after receiving all bytes even if the phase transition
immediately sets it again. While it's technically not necessary at the
moment because the state between clearing and setting RQM is not
observable by the guest, this is more explicit and matches how real
hardware works. It will actually become necessary in qemu once
asynchronous code paths are introduced.
This alone should have been enough to fix the CVE, but now we have two
lines of defense - even better.

The dynamic sysbus devices are attached to this platform bus device.
The platform bus device registers a machine init done notifier
whose role will be to bind the dynamic sysbus devices. Indeed
dynamic sysbus devices are created after machine init.
machvirt also registers a notifier that will build the device
tree nodes for the platform bus and its children dynamic sysbus
devices.

Device tree nodes for the platform bus and its children dynamic sysbus
devices are added in a machine init done notifier. To load the dtb once,
after those latter nodes are built and before ROM freeze, the actual
arm_load_kernel existing code is moved into a notifier notify function,
arm_load_kernel_notify. arm_load_kernel now only registers the
corresponding notifier.
Machine files that do not support platform bus stay unchanged. Machine
files willing to support dynamic sysbus devices must call arm_load_kernel
before sysbus-fdt arm_register_platform_bus_fdt_creator to make sure
dynamic sysbus device nodes are integrated in the dtb.

xen/pt: add a few PCI config space field descriptions
Since the next patch will turn all not explicitly described fields
read-only by default, those fields that have guest writable bits need
to be given explicit descriptors.
This is a preparatory patch for XSA-131.

xen/pt: mark reserved bits in PCI config space fields
The adjustments are solely to make the subsequent patches work right
(and hence make the patch set consistent), namely if permissive mode
(introduced by the last patch) gets used (as both reserved registers
and reserved fields must be similarly protected from guest access in
default mode, but the guest should be allowed access to them in
permissive mode).
This is a preparatory patch for XSA-131.

xen/pt: split out calculation of throughable mask in PCI config space handling
This is just to avoid having to adjust that calculation later in
multiple places.
Note that including ->ro_mask in get_throughable_mask()'s calculation
is only an apparent (i.e. benign) behavioral change: For r/o fields it
doesn't matter > whether they get passed through - either the same flag
is also set in emu_mask (then there's no change at all) or the field is
r/o in hardware (and hence a write won't change it anyway).

xen/MSI: don't open-code pass-through of enable bit modifications
Without this the actual XSA-131 fix would cause the enable bit to not

on the OR of emu_mask, ro_mask, and res_mask).
Note that the fiddling with the enable bit shouldn't really be done by
qemu, but making this work right (via libxc and the hypervisor) will
require more extensive changes, which can be postponed until after the
security issue got addressed.

xen/MSI-X: limit error messages
Limit error messages resulting from bad guest behavior to avoid allowing
the guest to cause the control domain's disk to fill.
The first message in pci_msix_write() can simply be deleted, as this
is indeed bad guest behavior, but such out of bounds writes don't
really need to be logged.
The second one is more problematic, as there guest behavior may only
appear to be wrong: For one, the old logic didn't take the mask-all bit
into account. And then this shouldn't depend on host device state (i.e.
the host may have masked the entry without the guest having done so).
Plus these writes shouldn't be dropped even when an entry is unmasked.
Instead, if they can't be made take effect right away, they should take
effect on the next unmasking or enabling operation - the specification
explicitly describes such caching behavior. Until we can validly drop
the message (implementing such caching/latching behavior), issue the
message just once per MSI-X table entry.
Note that the log message in pci_msix_read() similar to the one being
removed here is not an issue: "addr" being of unsigned type, and the
maximum size of the MSI-X table being 32k, entry_nr simply can't be
negative and hence the conditonal guarding issuing of the message will
never be true.
This is XSA-130.

xen: properly gate host writes of modified PCI CFG contents
The old logic didn't work as intended when an access spanned multiple
fields (for example a 32-bit access to the location of the MSI Message
Data field with the high 16 bits not being covered by any known field).
Remove it and derive which fields not to write to from the accessed
fields' emulation masks: When they're all ones, there's no point in
doing any host write.
This fixes a secondary issue at once: We obviously shouldn't make any
host write attempt when already the host read failed.
This is XSA-128.

arm_gicv2m: Add GICv2m widget to support MSIs
The ARM GICv2m widget is a little device that handles MSI interrupt
writes to a trigger register and ties them to a range of interrupt lines
wires to the GIC. It has a few status/id registers and the interrupt wires,
and that's about it.
A board instantiates the device by setting the base SPI number and
number SPIs for the frame. The base-spi parameter is indexed in the SPI
number space only, so base-spi == 0, means IRQ number 32. When a device
(the PCI host controller) writes to the trigger register, the payload is
the GIC IRQ number, so we have to subtract 32 from that and then index
into our frame of SPIs.
When instantiating a GICv2m device, tell PCI that we have instantiated
something that can deal with MSIs. We rely on the board actually wiring
up the GICv2m to the PCI host controller.

monitor: Use trad. command interface for HMP pcie_aer_inject_error
All QMP commands use the "new" handler interface (mhandler.cmd_new).
Most HMP commands still use the traditional interface (mhandler.cmd),
but a few use the "new" one. Complicates handle_user_command() for no
gain, so I'm converting these to the traditional interface.
pcie_aer_inject_error's implementation is split into the
hmp_pcie_aer_inject_error() and pcie_aer_inject_error_print(). The
former is a peculiar crossbreed between HMP and QMP handler. On
success, it works like a QMP handler: store QDict through ret_data
parameter, return 0. Printing the QDict is left to
pcie_aer_inject_error_print(). On failure, it works more like an HMP
handler: print error to monitor, return negative number.
To convert to the traditional interface, turn
pcie_aer_inject_error_print() into a command handler wrapping around
hmp_pcie_aer_inject_error(). By convention, this command handler
should be called hmp_pcie_aer_inject_error(), so rename the existing
hmp_pcie_aer_inject_error() to do_pcie_aer_inject_error().

monitor: Drop broken, unused asynchronous command interface
The asynchronous monitor command interface goes back to commit 940cc30
(Jan 2010). Added a third case to command execution. The hope back
then according to the commit message was that all commands get
converted to the asynchronous interface, killing off the other two
cases. Didn't happen.
The initial asynchronous commands balloon and info balloon were
converted back to synchronous long ago (commit 96637bc and d72f32),
with commit messages calling the asynchronous interface "not fully
working" and "deprecated". The only other user went away in commit
3b5704b.
New code generally uses synchronous commands and asynchronous events.
What exactly is still "not fully working" with asynchronous commands?
Well, here's a bug that defeats actual asynchronous use pretty
reliably: the reply's ID is wrong (and has always been wrong) unless
you use the command synchronously! To reproduce, we need an
asynchronous command, so we have to go back before commit 3b5704b.
Run QEMU with spice:
$ qemu-system-x86_64 -nodefaults -S -spice port=5900,disable-ticketing -qmp stdio
{"QMP": {"version": {"qemu": {"micro": 94, "minor": 2, "major": 2}, "package": ""}, "capabilities": []}}
Connect a spice client in another terminal:
$ remote-viewer spice://localhost:5900
Set up a migration destination dummy in a third terminal:
$ socat TCP-LISTEN:12345 STDIO
Now paste the following into the QMP monitor:
{ "execute": "qmp_capabilities", "id": "i0" }
{ "execute": "client_migrate_info", "id": "i1", "arguments": { "protocol": "spice", "hostname": "localhost", "port": 12345 } }
{ "execute": "query-kvm", "id": "i2" }
Produces two replies immediately, one to qmp_capabilities, and one to
query-kvm:
{"return": {}, "id": "i0"}
{"return": {"enabled": false, "present": true}, "id": "i2"}
Both are correct. Two lines of debug output from libspice-server not
shown.
Now EOF socat's standard input to make it close the connection. This
makes the asynchronous client_migrate_info complete. It replies:
{"return": {}}
Bug: "id": "i1" is missing. Two lines of debug output from
libspice-server not shown. Cherry on top: storage for the missing ID
is leaked.
Get rid of this stuff before somebody hurts himself with it.

Make features 64bit wide everywhere.
On migration a full 64bit guest_features field is sent if one of the
high bits is set, in addition to the lower 32bit guest_features field
which must stay for compatibility reasons. That way we send the lower
32 feature bits twice, but the code is simpler because we don't have
to split and compose the 64bit features into two 32bit fields.

Extend TPM TIS interface to support TPM 2
Following the recent upgrade to version 1.3, extend the TPM TIS
interface with capabilities introduced for support of a TPM 2.
TPM TIS for TPM 2 introduced the following extensions beyond the
TPM TIS 1.3 (used for TPM 1.2):
- A new 32bit interface Id register was introduced.
- New flags for the status (STS) register were defined.
- New flags for the capability flags were defined.
Support the above if a TPM TIS 1.3 for TPM 2 is used with a TPM 2
on the backend side. Support the old TPM TIS 1.3 configuration if a
TPM 1.2 is being used. A subsequent patch will then determine which
TPM version is being used in the backend.

It is Very annoying to carry forward an outdatEd coNtroller with a mOdern

- "-device isa-fdc" is not passed on the command line (nor in the config

- no "-drive if=floppy,..." is requested.

i386/pc_q35: don't insist on board FDC if there's no default floppy
The "no_floppy = 1" machine class setting causes "default_floppy" in
main() to become zero. Consequently, default_drive() will not call
drive_add() and drive_new() for IF_FLOPPY, index=0, meaning that no
default floppy drive will be created for the virtual machine. In that
case, board code should also not insist on the creation of the
board-default FDC.
The board-default FDC will still be created if the user requests a floppy
drive with "-drive if=floppy".
Additionally, separate FDCs can be specified manually with "-device
isa-fdc". They allow the
-device isa-fdc,driveA=...
syntax that is more flexible than the one required by the board-default
FDC:
-global isa-fdc.driveA=...
This patch doesn't change the behavior observably, as all Q35 machine
types have "no_floppy = 0".

Even if board code decides not to request the creation of the FDC (keyed

nevertheless if the user passes '-drive if=floppy' on the command line.
Otherwise '-drive if=floppy' would break without explicit '-device

i386/pc: pc_basic_device_init(): delegate FDC creation request
This patch introduces no observable change, but it allows the callers of
pc_basic_device_init(), ie. pc_init1() and pc_q35_init(), to request (or
not request) the creation of the FDC explicitly.
At the moment both callers pass constant create_fdctrl=true (hence no
observable change).
Assuming a board passes create_fdctrl=false, "floppy" will be NULL on
output, and (beyond the FDC not being created) that NULL will be passed on
to pc_cmos_init(). Luckily, pc_cmos_init() already handles that case.

pc: acpi: fix pvpanic for buggy guests
In the old times, we always had pvpanic in ACPI and a _STA method told
the guest not to use it. Automatic generation dropped the _STA method
as the specification says that missing _STA means enabled and working.
Some guests (Linux) had buggy drivers and this change made them unable
to utilize pvpanic.
A Linux patch is posted as well, but I think it's worth to make pvpanic
useable on old guests at the price of three lines and few bytes of SSDT.
The old _STA method was
Method (_STA, 0, NotSerialized) {
Store (PEST, Local0)
If (LEqual (Local0, Zero)) {
Return (Zero) }
Else {
Return (0x0F) }}
Igor pointed out that we don't need to use a method to return a constant
and that 0xB (don't show in UI) is the common definition now.
Also, the device used to be PEVT. (PEVT as in "panic event"?)

pc: Don't use QEMUMachine anymore
Now that we have a DEFINE_PC_MACHINE helper macro that just requires an
initialization function, it is trivial to convert them to register a QOM
machine class directly, instead of using QEMUMachine.

commit b6b5c8e492ae7b71a16fe702b7409bff0feebfa7
Author: Eduardo Habkost <ehabkost@redhat.com>
Date: Fri May 15 14:18:52 2015 -0300
pc: Define MACHINE_OPTIONS macros consistently for all machines
Define a MACHINE_OPTIONS macro for each PC machine, and move every field
inside the QEMUMachine structs to the macros, except for name, init, and
compat_props.
This also ensures that all MACHINE_OPTIONS inherit the fields from the
next version, so their definitions carry only the changes that exist
between one version and the next one.
Comments about specific cases:
pc-*-2.1:
Existing PC_*_2_1_MACHINE_OPTIONS macros were defined as:
PC_*_MACHINE_OPTIONS,
.default_machine_opts = "firmware=bios-256k.bin"
PC_*_2_2_MACHINE_OPTIONS is:
PC_*_2_3_MACHINE_OPTIONS
which is expanded to:
PC_*_MACHINE_OPTIONS,
.default_machine_opts = "firmware=bios-256k.bin",
.default_display = "std"
The only difference between 2_1 and 2_2 is .default_display, that's why
we didn't reuse PC_*_2_2_MACHINE_OPTIONS. The good news is that having
multiple initializers for a field is allowed by C99, and the last
initializer overrides the previous ones.
So we can reuse the 2_2 macro in 2_1 and define PC_*_2_1_MACHINE_OPTIONS
as:
PC_*_2_2_MACHINE_OPTIONS,
.default_display = NULL
pc-*-1.7:
PC_*_1_7_MACHINE_OPTIONS was defined as:
PC_*_MACHINE_OPTIONS
PC_*_2_0_MACHINE_OPTIONS is defined as:
PC_*_2_1_MACHINE_OPTIONS
which is expanded to:
PC_*_2_2_MACHINE_OPTIONS,
.default_display = NULL
which is expanded to:
PC_*_2_3_MACHINE_OPTIONS,
.default_display = NULL
which is expanded to:
PC_*_MACHINE_OPTIONS,
.default_machine_opts = "firmware=bios-256k.bin",
.default_display = "std",
.default_display = NULL /* overrides the previous line */
So, the only difference between PC_*_1_7_MACHINE_OPTIONS and
PC_*_2_0_MACHINE_OPTIONS is .default_machine_opts (as .default_display
is not explicitly set by PC_*_MACHINE_OPTIONS so it is NULL).
So we can keep the macro reuse pattern and define
PC_*_2_0_MACHINE_OPTIONS as:
PC_*_2_0_MACHINE_OPTIONS,
.default_machine_opts = NULL
pc-*-2.4 (alias and is_default fields):
Set alias and is_default fields inside the 2.4 MACHINE_OPTIONS macro,
and clear it in the 2.3 macro (that reuses the 2.4 macro).
hw_machine:
As all the machines older than v1.0 set hw_version explicitly, we can
safely move the field to the MACHINE_OPTIONS macros without affecting
the other versions that reuse them.
init function:
Some machines had the init function set inside the MACHINE_OPTIONS
macro. Move it to the QEMUMachine declaration, to keep it consistent
with the other machines.

piix: Move pc-0.1[23] rombar compat props to PC_COMPAT_0_13
The VGA and vmware-svga rombar compat properties were added by commit
281a26b15b4adcecb8604216738975abd754bea8, but only to pc-0.13 and
pc-0.12. This breaks the PC_COMPAT_* nesting pattern we currently
follow.
The new variables will now be inherited by pc-0.11 and older, but
pc-0.11 and pc-0.10 already have PCI.rombar=0 on compat_props, so they
shouldn't be affected at all.

The compat property was added by commit
9dbcca5aa13cb9ab40788ac4c56bc227d94ca920, and the pc-0.12 and older
machine-types were not changed because virtio-9p-pci was introduced on QEMU
0.13 (commit 9f10751365b26b13b8a9b67e0e90536ae3d282df). The only problem is
that this breaks the PC_COMPAT_* nesting pattern we currently use.
So, move the property to PC_COMPAT_0_13. This make pc-0.12 and older inherit
it, but that shouldn't be an issue as QEMU 0.12 didn't have virtio-9p-pci.

qapi: add dirty bitmap status
Bitmaps can be in a handful of different states with potentially
more to come as we tool around with migration and persistence patches.
Management applications may need to know why certain bitmaps are
unavailable for various commands, e.g. busy in another operation,
busy being migrated, etc.
Right now, all we offer is BlockDirtyInfo's boolean member 'frozen'.
Instead of adding more booleans, replace it by an enumeration member
'status' with values 'active' and 'frozen'. Then add new value
'disabled'.
Incompatible change. Fine because the changed part hasn't been
released so far.

target-arm: Avoid buffer overrun on UNPREDICTABLE ldrd/strd
A LDRD or STRD where rd is not an even number is UNPREDICTABLE.
We were letting this fall through, which is OK unless rd is 15,
in which case we would attempt to do a load_reg or store_reg
to a nonexistent r16 for the second half of the double-word.
Catch the odd-numbered-rd cases and UNDEF them instead.
To do this we rearrange the structure of the code a little
so we can put the UNDEF catches at the top before we've
allocated TCG temporaries.

As part of this cleanup, move the user-mode-only

visible, and rename the softmmu-only utility function
arm_cpu_handle_mmu_fault to arm_tlb_fill so it's clear

kbd: add brazil kbd keys to qemu
The brazilian computer keyboard layout has two extra keys (compared to
the usual 105-key intl ps/2 keyboard). This patch makes these two keys
known to qemu.
For historic reasons qemu has two ways to specify a key: A QKeyCode
(name-based) or a number (ps/2 scancode based). Therefore we have to
update multiple places to make new keys known to qemu:
(1) The QKeyCode definition in qapi-schema.json
(2) The QKeyCode <-> number mapping table in ui/input-keymap.c
This patch does just that. With this patch applied you can send those
two keys to the guest using the send-key monitor command.

s390x: Vector Register IOCTLs
Handle the actual syncing of the vector registers with kernel space,
via the get/put register IOCTLs.
The vector registers that were introduced with the z13 overlay
the existing floating point registers. FP registers 0-15 are
the high-halves of vector registers 0-15. Thus, remove the
freg fields and replace them with the equivalent vector field
to avoid errors in duplication. Moreover, synchronize either the
vector registers via kvm_sync_regs, or floating point registers
via the GET/SET FPU IOCTLs.

net/net: Record usage status of mac address
Currently QEMU dynamically generates mac address for the NIC which
doesn't specify the mac address. But when we hotplug a NIC without
specifying mac address, the mac address will increase for the same NIC
along with hotplug and hot-unplug, and at last it will overflow. And if
we codeplug one NIC with mac address e.g. "52:54:00:12:34:56", then
hotplug one NIC without specifying mac address and the mac address of
the hotplugged NIC is duplicate of "52:54:00:12:34:56".
This patch add a mac_table to record the usage status and free the mac
address when the NIC is unrealized.

tap: Improve -netdev/netdev_add/-net/... tap error reporting
When -netdev tap fails, it first reports a specific error, then a
generic one, like this:
$ qemu-system-x86_64 -netdev tap,id=foo
qemu-system-x86_64: -netdev tap,id=foo: could not configure /dev/net/tun: Operation not permitted
qemu-system-x86_64: -netdev tap,id=foo: Device 'tap' could not be initialized
With the command line, the messages go to stderr. In HMP, they go to
the monitor. In QMP, the second one becomes the error reply, and the
first one goes to stderr.
Convert net_init_tap() to Error. This suppresses the unwanted second
message, and makes the specific error the QMP error reply.

tap: Improve -netdev/netdev_add/-net/... bridge error reporting
When -netdev bridge fails, it first reports a specific error, then a
generic one, like this:
$ qemu-system-x86_64 -netdev bridge,id=foo
failed to launch bridge helper
qemu-system-x86_64: -netdev bridge,id=foo: Device 'bridge' could not be initialized
The first message goes to stderr. Wrong for HMP, because errors need
to go to the monitor there.
The second message goes to stderr for -netdev, to the monitor for HMP
netdev_add, and becomes the error reply for QMP netdev_add.
Convert net_bridge_run_helper() to Error, and propagate its errors
through net_init_bridge(). This ensures the error gets reported where
the user is, and suppresses the unwanted second message.
While there, improve the error messages a bit.
The above example becomes:
$ qemu-system-x86_64 -netdev bridge,id=foo
qemu-system-x86_64: -netdev bridge,id=foo: bridge helper failed
net_init_tap() also uses net_bridge_run_helper(). Propagate its
errors there as well. Improves reporting these errors with -netdev
tap & friends.

net: Permit incremental conversion of init functions to Error
Error reporting for netdev_add is broken: the net_client_init_fun[]
report the actual errors with (at best) error_report(), and their
caller net_client_init1() makes up a generic error on top.
For command line and HMP, this produces an mildly ugly error cascade.
In QMP, the actual errors go to stderr, and the generic error becomes
the command's error reply.
To fix this, we need to convert the net_client_init_fun[] to Error.
To permit fixing them one by one, add an Error ** parameter to the
net_client_init_fun[]. If the call fails without returning an Error,
make up the same generic Error as before. But if it returns one, use
that instead. Since none of them does so far, no functional change.

net: Change help text to list -netdev instead of -net by default
Looking at the output of "qemu-system-xxx -help", you easily get
the impression that "-net" is the preferred way instead of "-netdev"
to specify host network interface, since the "-net" option is
omnipresent but the "-netdev" option is only listed as a one-liner
at the end. This is ugly since "-net" is considered as legacy and
even might be removed one day. Thus, this patch switches the output
to explain the host network interfaces with the "-netdev" option
instead, moving the old "-net" option into some few lines at
the end.

ahci: do not remap clb/fis unconditionally
This continues the IOMMU fix from 2.3, where we should not attempt
to remap the CLB or FIS RX buffers if the AHCI device is currently
running.
The same applies to migration: keep our mitts off these registers
unless the device is supposed to be on.
Does not impact backwards compatibility for the AHCI device.

Instead of converting each byte one-at-a-time and then sending each byte

This gives a moderate speed boost to memread() and memwrite() functions.

libqos/ahci: Swap memread/write with bufread/write
Where it makes sense, use the new faster primitives.
For generally small reads/writes such as for the PRDT
and FIS packets, stick with the more wasteful but
easier to debug memread/memwrite.
For ahci-test (before migration tests):

qtest: add memset to qtest protocol
Previously, memset was just a frontend to write() and only
stupidly sent the pattern many times across the wire.
Let's not discuss who stupidly wrote it like that in the first place.

qtest: Add base64 encoded read/write
For larger pieces of data that won't need to be debugged and
viewing the hex nibbles is unlikely to be useful, we can encode
data using base64 instead of encoding each byte as %02x, which
leads to some space savings and faster reads/writes.
For now, the default is left as hex nibbles in memwrite() and memread().
For the purposes of making qtest io easier to read and debug, some
callers may want to specify using the old encoding format for small
patches of data where the savings from base64 wouldn't be that profound.
memwrite/memread use a data encoding that takes 2x the size of the original
buffer, but base64 uses "only" (4/3)x, so for larger buffers we can save a
decent amount of time and space.

qtest: allow arbitrarily long sends
qtest currently has a static buffer of size 1024 that if we
overflow, ignores the additional data silently which leads
to hangs or stream failures.
Use glib's string facilities to allow arbitrarily long data,
but split this off into a new function, qtest_sendf.
Static data can still be sent using qtest_send, which avoids
the malloc/copy overhead.

qtest/ahci: Add migration test
Notes:
* The migration is performed on QOSState objects.
* The migration is performed in such a way that it does not assume
consistency between the allocators attached to each. That is to say,
you can use each QOSState object completely independently and then at
an arbitrary point decide to migrate, and the destination object will
now be consistent with the memory within the source guest. The source
object that was migrated from will have a completely blank allocator.
ahci-test.c:
- verify_state is added
- ahci_migrate is added as a frontend to migrate
- test_migrate_sanity test case is added.

qemu-io: prompt for encryption keys when required
The qemu-io tool does not check if the image is encrypted so
historically would silently corrupt the sectors by writing
plain text data into them instead of cipher text. The earlier
commit turns this mistake into a fatal abort, so check for
encryption and prompt for key when required.
This enables us to add unit tests to ensure we don't break
the ability of qemu-img to convert existing encrypted qcow2
files into a non-encrypted format.

qcow2/qcow: protect against uninitialized encryption key
When a qcow[2] file is opened, if the header reports an
encryption method, this is used to set the 'crypt_method_header'
field on the BDRVQcow[2]State struct, and the 'encrypted' flag
in the BDRVState struct.
When doing I/O operations, the 'crypt_method' field on the
BDRVQcow[2]State struct is checked to determine if encryption
needs to be applied.
The crypt_method_header value is copied into crypt_method when
the bdrv_set_key() method is called.
The QEMU code which opens a block device is expected to always
do a check
if (bdrv_is_encrypted(bs)) {
bdrv_set_key(bs, ....key...);
}
If code forgets to do this, then 'crypt_method' is never set
and so when I/O is performed, QEMU writes plain text data
into a sector which is expected to contain cipher text, or
when reading, will return cipher text instead of plain
text.
Change the qcow[2] code to consult bs->encrypted when deciding
whether encryption is required, and assert(s->crypt_method)
to protect against cases where the caller forgets to set the
encryption key.
Also put an assert in the set_key methods to protect against
the case where the caller sets an encryption key on a block
device that does not have encryption

qemu-iotests: Make debugging python tests easier
Adding "-d" option. The output goes to "tee" so it appears in your
console. Also, raise the verbosity of unnitest runner.
When testing a topic branch, it's possible that a bug introduced by a
code change makes the python test case hang, with debug output, it is
much easier to locate the problem.
This can also be helpful if you want to watch the progress of a python
test, it offers you a way to sense the speed of each test case method
you're writing.
Note: because there is no easy way to get *both* the verbose output and
the output expected by ./check comparison, the case would always fail
with an "output mismatch". The sole purpose of using this option is
giving developers a quick way to debug when things go wrong.

qcow2: use a hash to look for entries in the L2 cache
The current cache algorithm traverses the array starting always from
the beginning, so the average number of comparisons needed to perform
a lookup is proportional to the size of the array.
By using a hash of the offset as the starting point, lookups are
faster and independent from the array size.
The hash is computed using the cluster number of the table, multiplied
by 4 to make it perform better when there are collisions.
In my tests, using a cache with 2048 entries, this reduces the average
number of comparisons per lookup from 430 to 2.5.

qcow2: use an LRU algorithm to replace entries from the L2 cache
The current algorithm to evict entries from the cache gives always
preference to those in the lowest positions. As the size of the cache
increases, the chances of the later elements of being removed decrease
exponentially.
In a scenario with random I/O and lots of cache misses, entries in
positions 8 and higher are rarely (if ever) evicted. This can be seen
even with the default cache size, but with larger caches the problem
becomes more obvious.
Using an LRU algorithm makes the chances of being removed from the
cache independent from the position.

Since all tables are now stored together, it is possible to obtain

qcow2: use one single memory block for the L2/refcount cache tables
The qcow2 L2/refcount cache contains one separate table for each cache
entry. Doing one allocation per table adds unnecessary overhead and it
also requires us to store the address of each table separately.
Since the size of the cache is constant during its lifetime, it's
better to have an array that contains all the tables using one single
allocation.
In my tests measuring freshly created caches with sizes 128MB (L2) and
32MB (refcount) this uses around 10MB of RAM less.

vmdk: Fix overflow if l1_size is 0x20000000
Richard Jones caught this bug with afl fuzzer.
In fact, that's the only possible value to overflow (extent->l1_size =
0x20000000) l1_size:
l1_size = extent->l1_size * sizeof(long) => 0x80000000;
g_try_malloc returns NULL because l1_size is interpreted as negative
during type casting from 'int' to 'gsize', which yields a enormous
value. Hence, by coincidence, we get a "not too bad" behavior:
qemu-img: Could not open '/tmp/afl6.img': Could not open
'/tmp/afl6.img': Cannot allocate memory
Values larger than 0x20000000 will be refused by the validation in
vmdk_add_extent.
Values smaller than 0x20000000 will not overflow l1_size.

qcow2: Flush pending discards before allocating cluster
Before a freed cluster can be reused, pending discards for this cluster
must be processed.
The original assumption was that this was not a problem because discards
are only cached during discard/write zeroes operations, which are
synchronous so that no concurrent write requests can cause cluster
allocations.
However, the discard/write zeroes operation itself can allocate a new L2
table (and it has to in order to put zero flags there), so make sure we
can cope with the situation.
This fixes https://bugs.launchpad.net/bugs/1349972.

A bit of Boolean algebra (and common sense) tells us that the

This is the opposite of the "if" that sets BDRV_BLOCK_ALLOCATED,

Commit fc3959e466 fixed bdrv_co_write_zeroes which is the common case
for this bug, but it still exists in bdrv_aio_write_zeroes. A simpler
fix would be in bdrv_co_do_pwritev which is the NULL dereference point
and covers both cases.
So don't access it in bdrv_co_do_pwritev in this case, use three aligned
writes.

block: align bounce buffers to page
The following sequence
int fd = open(argv[1], O_RDWR | O_CREAT | O_DIRECT, 0644);
for (i = 0; i < 100000; i++)
write(fd, buf, 4096);
performs 5% better if buf is aligned to 4096 bytes.
The difference is quite reliable.
On the other hand we do not want at the moment to enforce bounce
buffering if guest request is aligned to 512 bytes.
The patch changes default bounce buffer optimal alignment to
MAX(page size, 4k). 4k is chosen as maximal known sector size on real
HDD.
The justification of the performance improve is quite interesting.
From the kernel point of view each request to the disk was split
by two. This could be seen by blktrace like this:
9,0 11 1 0.000000000 11151 Q WS 312737792 + 1023 [qemu-img]
9,0 11 2 0.000007938 11151 Q WS 312738815 + 8 [qemu-img]
9,0 11 3 0.000030735 11151 Q WS 312738823 + 1016 [qemu-img]

9,0 11 7 0.000051236 11151 Q WS 312740871 + 1017 [qemu-img]
9,0 5 1 0.169071519 11151 Q WS 312741888 + 1023 [qemu-img]
After the patch the pattern becomes normal:
9,0 6 1 0.000000000 12422 Q WS 314834944 + 1024 [qemu-img]
9,0 6 2 0.000038527 12422 Q WS 314835968 + 1024 [qemu-img]
9,0 6 3 0.000072849 12422 Q WS 314836992 + 1024 [qemu-img]
9,0 6 4 0.000106276 12422 Q WS 314838016 + 1024 [qemu-img]
and the amount of requests sent to disk (could be calculated counting
number of lines in the output of blktrace) is reduced about 2 times.
Both qemu-img and qemu-io are affected while qemu-kvm is not. The guest
does his job well and real requests comes properly aligned (to page).

block: minimal bounce buffer alignment
The patch introduces new concept: minimal memory alignment for bounce
buffers. Original so called "optimal" value is actually minimal required
value for aligment. It should be used for validation that the IOVec
is properly aligned and bounce buffer is not required.
Though, from the performance point of view, it would be better if
bounce buffer or IOVec allocated by QEMU will be aligned stricter.
The patch does not change any alignment value yet.

This is the behavior in the operating system, for example Linux's
blkdev_write_iter has the following:

This does not apply to opening a device for read/write, when the
device only supports read-only operation. In this case any of
EACCES, EPERM or EROFS is acceptable depending on why writing is

configure: Add workaround for ccache and clang
Test if ccache is interfering with semantic analysis of macros,
disable its habit of trying to compile already pre-processed
versions of code if so. ccache attempts to save time by compiling
pre-processed versions of code, but this disturbs clang's static
analysis enough to produce false positives.
ccache allows us to disable this feature, opting instead to
compile the original version instead of its preprocessed version.
This makes ccache much slower for cache misses, but at least it
becomes usable with QEMU/clang.
This workaround only activates for users using ccache AND clang,
and only if their configuration is observed to be producing warnings.
You may need to clear your ccache for builds started without -Werror,

configure: silence glib unknown attribute __alloc_size__
The glib headers use GCC attributes. Unfortunately the __GNUC__ and
__GNUC_MINOR__ version macros are also defined by clang, but clang
doesn't support the same attributes as GCC.
clang 3.5.0 does not support the __alloc_size__ attribute:
https://github.com/llvm-mirror/clang/commit/c047507a9a79e89fc8339e074fa72822a7e7ea73
The following warning is produced:
gstrfuncs.h:257:44: warning: unknown attribute '__alloc_size__' ignored [-Wunknown-attributes]
G_GNUC_MALLOC G_GNUC_ALLOC_SIZE(2);
gmacros.h:67:45: note: expanded from macro 'G_GNUC_ALLOC_SIZE'
#define G_GNUC_ALLOC_SIZE(x) __attribute__((__alloc_size__(x)))
This patch checks whether glib headers cause warnings and disables
-Wunknown-attributes if it is able to.

block/parallels: optimize linear image expansion
Plain image expansion spends a lot of time to update image file size.
This seriously affects the performance. The following simple test
qemu_img create -f parallels -o cluster_size=64k ./1.hds 64G
qemu_io -n -c "write -P 0x11 0 1024M" ./1.hds
could be improved if the format driver will pre-allocate some space
in the image file with a reasonable chunk.
This patch preallocates 128 Mb using bdrv_write_zeroes, which should
normally use fallocate() call inside. Fallback to older truncate()
could be used as a fallback using image open options thanks to the
previous patch.
The benefit is around 15%.

block/parallels: add prealloc-mode and prealloc-size open paramemets
This is preparational commit for tweaks in Parallels image expansion.
The idea is that enlarge via truncate by one data block is slow. It
would be much better to use fallocate via bdrv_write_zeroes and
expand by some significant amount at once.
Original idea with sequential file writing to the end of the file without
fallocate/truncate would be slower than this approach if the image is
expanded with several operations:
- each image expanding means file metadata update, i.e. filesystem
journal write. Truncate/write to newly truncated space update file
metadata twice thus truncate removal helps. With fallocate call
inside bdrv_write_zeroes file metadata is updated only once and
this should happen infrequently thus this approach is the best one
for the image expansion
- tail writes are ordered, i.e. the guest IO queue could not be sent
immediately to the host introducing additional IO delays
This patch just adds proper parameters into BDRVParallelsState and
performs options parsing in parallels_open.

block/parallels: delay writing to BAT till bdrv_co_flush_to_os
The idea is that we do not need to immediately sync BAT to the image as
from the guest point of view there is a possibility that IO is lost
even in the physical controller until flush command was finished.
bdrv_co_flush_to_os is exactly the right place for this purpose.
Technically the patch uses loaded BAT data as a cache and performs
actual on-disk metadata updates in parallels_co_flush_to_os callback.
This patch speed ups
qemu-img create -f parallels -o cluster_size=64k ./1.hds 64G
qemu-io -f parallels -c "write -P 0x11 0 1024k" 1.hds
writing from 50-60 Mb/sec to 80-90 Mb/sec on rotational media and
from 160 Mb/sec to 190 Mb/sec on SSD disk.

block/parallels: implement incorrect close detection
The software driver must set inuse field in Parallels header to
0x746F6E59 when the image is opened in read-write mode. The presence of
this magic in the header on open forces image consistency check.
There is an unfortunate trick here. We can not check for inuse in
parallels_check as this will happen too late. It is possible to do
that for simple check, but during the fix this would always report
an error as the image was opened in BDRV_O_RDWR mode. Thus we save
the flag in BDRVParallelsState for this.
On the other hand, nothing should be done to clear inuse in
parallels_check. Generic close will do the job right.

block/parallels: switch to bdrv_read
Switch the .bdrv_read method implementation from using bdrv_pread() to
bdrv_read() on the underlying file, since the latter is subject to i/o
throttling while the former is not.
Besides, since bdrv_read() operates in sectors rather than bytes, adjust
the helper functions to do so too.

qemu-sockets: Report explicit error if unlink fails
Consider this case:
$ ls -ld ~/root-owned/
drwx--x--x. 2 root root 4096 Apr 29 12:55 /home/crobinso/root-owned/
$ ls -l ~/root-owned/foo.sock
-rwxrwxrwx. 1 crobinso crobinso 0 Apr 29 12:55 /home/crobinso/root-owned/foo.sock
$ qemu-system-x86_64 -vnc unix:~/root-owned/foo.sock
qemu-system-x86_64: -vnc unix:/home/crobinso/root-owned/foo.sock: Failed to start VNC server: Failed to bind socket to /home/crobinso/root-owned/foo.sock: Address already in use
...which is techinically true, but the real error is that we failed to
unlink. So report it.
This may seem pathological but it's a real possibility via libvirt.

Rather than tweak the string possibly show unix: value as well,

serial: fix multi-pci card error cleanup.
Put the number of serial ports into a local variable in
multi_serial_pci_realize, then increment the port count
(pci->ports) as we initialize the serial port cores.
Now pci->ports always holds the number of successfully
initialized ports and we can use multi_serial_pci_exit
to properly cleanup the already initialized bits in case
of a init failure.

ui/cocoa: Avoid deprecated NSOKButton/NSCancelButton constants
In OSX 10.10, the NSOKButton and NSCancelButton constants are deprecated
and provoke compiler warnings. Avoid them by using the
NSFileHandlingPanelCancelButton and NSFileHandlingPanelOKButton constants
instead. These are the documented correct constants for the 10.6-and-up
beginSheetModalForWindow API we use. We also use the same method for
the pre-10.6 compatibility code path, but conveniently the constant
values are the same and the constant names have been present since 10.0.
Preferring the constant names that match the non-legacy API makes more
sense anyway.

ui/cocoa: Declare that QemuCocoaAppController implements NSApplicationDelegate
Our class QemuCocoaAppController implements the NSApplicationDelegate
interface, and we pass an object of this class to [NSApp setDelegate].
However, we weren't declaring in the class definition that we implemented
this interface; in OSX 10.10 this provokes the following (slighly
misleading) warning:
ui/cocoa.m:1031:24: warning: sending 'QemuCocoaAppController *' to parameter of
incompatible type 'id<NSFileManagerDelegate>'

^

have to surround the relevant part of the @interface line with an ifdef.

ui/cocoa: Drop tests for CGImageCreateWithImageInRect support
The code that tries to test at both compiletime and runtime
for whether CGImageCreateWithImageInRect is supported provokes
a compile warning on OSX 10.3:
ui/cocoa.m:378:13: warning: comparison of function 'CGImageCreateWithImageInRect'
equal to a null pointer is always false[-Wtautological-pointer-compare]
if (CGImageCreateWithImageInRect == NULL) { // test if "CGImageCreateWithImageInRect" is
supported on host at runtime
^~~~~~~~~~~~~~~~~~~~~~~~~~~~ ~~~~
The simplest way to deal with this is just to drop this code,
since we don't in practice support OSX 10.4 anyway. (10.5 was
released in 2007 and is the last PPC version, so is the earliest
we really need to continue to support at all.)

target-arm: cpu64: generalise name of A57 regs
Rename some A57 CP register variables in preparation for support for
Cortex A53. Use "a57_a53" to describe the shareable features. Some of
the CP15 registers (such as ACTLR) are specific to implementation, but
we currently just RAZ them so continue with that as the policy for both
A57 and A53 processors under a shared definition.

qapi: qapi-commands.py option --type is unused, drop it
Anything but --type sync (which is the default) suppresses output
entirely, which makes no sense.
Dates back to the initial commit c17d990. Commit message says
"Currently only generators for synchronous qapi/qmp functions are
supported", so maybe output other than "synchronous qapi/qmp" was
planned at the time, to be selected with --type.
Should other kinds of output ever materialize, we can put the option
back.

qapi: Make c_type() consistently convert qapi names
Continuing the string of cleanups for supporting downstream names
containing '.', this patch focuses on ensuring c_type() can
handle a downstream name. This patch alone does not fix the
places where generator output should be calling this function
but was open-coding things instead, but it gets us a step closer.
In particular, the changes to c_list_type() and type_name() mean
that type_name(FOO) now handles the case when FOO contains '.',
'-', or is a ticklish identifier other than a builtin (builtins
are exempted because ['int'] must remain mapped to 'intList' and
not 'q_intList'). Meanwhile, ['unix'] now maps to 'q_unixList'
rather than 'unixList', to match the fact that 'unix' is ticklish;
however, our naming conventions state that complex types should
start with a capital, so no type name following conventions will
ever have the 'q_' prepended.
Likewise, changes to c_type() mean that c_type(FOO) properly
handles an enum or complex type FOO with '.' or '-' in the
name, or is a ticklish identifier (again, a ticklish identifier
as a type name violates conventions).

qapi: Tidy c_type() logic
c_type() is designed to be called on both string names and on
array designations, so 'name' is a bit misleading because it
operates on more than strings. Also, no caller ever passes
an empty string. Finally, + notation is a bit nicer to read
than '%s' % value for string concatenation.

Now that the two functions are identical, we only need one of them,

qapi: Fix C identifiers generated for names containing '.'
c_fun() maps '.' to '_', c_var() doesn't. Nothing prevents '.' in
QAPI names that get passed to c_var().
Which QAPI names get passed to c_fun(), to c_var(), or to both is not
obvious. Names of command parameters and struct type members get
passed to c_var().
c_var() strips a leading '*', but this cannot happen. c_fun()
doesn't.
Fix c_var() to work exactly like c_fun().
Perhaps they should be replaced by a single mapping function.

hw/intc/arm_gic: Add grouping support to gic_update()
Add support to gic_update() for determining the current IRQ
and FIQ status when interrupt grouping is supported. This
simply requires that instead of always raising IRQ we
check the group of the highest priority pending interrupt
and the GICC_CTLR.FIQEn bit to see whether we should raise
IRQ or FIQ.

hw/intc/arm_gic: Make ICCICR/GICC_CTLR banked
ICCICR/GICC_CTLR is banked in GICv1 implementations with Security
Extensions or in GICv2 in independent from Security Extensions.
This makes it possible to enable forwarding of interrupts from
the CPU interfaces to the connected processors for Group0 and Group1.
We also allow to set additional bits like AckCtl and FIQEn by changing
the type from bool to uint32. Since the field does not only store the
enable bit anymore and since we are touching the vmstate, we use the
opportunity to rename the field to cpu_ctlr.

hw/intc/arm_gic: Add Interrupt Group Registers
The Interrupt Group Registers allow the guest to configure interrupts
into one of two groups, where Group0 are higher priority and may
be routed to IRQ or FIQ, and Group1 are lower priority and always
routed to IRQ. (In a GIC with the security extensions Group0 is
Secure interrupts and Group 1 is NonSecure.)
The GICv2 always supports interrupt grouping; the GICv1 does only
if it implements the security extensions.
This patch implements the ability to read and write the registers;
the actual functionality the bits control will be added in a
subsequent patch.

armv7m_nvic: systick: Reload the RELOAD value and count down only if ENABLE bit is set
Consider the following pseudo code to configure SYSTICK (The
recommended programming sequence from "the definitive guide to the
arm cortex-m3"):
SYSTICK Reload Value Register = 0xffff
SYSTICK Current Value Register = 0
SYSTICK Control and Status Register = 0x7
The pseudo code "SYSTICK Current Value Register = 0" leads to invoking
systick_reload(). As a consequence, the systick.tick member is updated
and the systick timer starts to count down when the ENABLE bit of
SYSTICK Control and Status Register is cleared.
The worst case is that: during the system initialization, the reset
value of the SYSTICK Control and Status Register is 0x00000000.
When the code "SYSTICK Current Value Register = 0" is executed, the
systick.tick member is accumulated with "(s->systick.reload + 1) *
systick_scale(s)". The systick_scale() gets the external_ref_clock
scale because the CLKSOURCE bit of the SYSTICK Control and Status
Register is cleared. This is the incorrect behavior because of the
code "SYSTICK Control and Status Register = 0x7". Actually, we want
the processor clock instead of the external reference clock.
This incorrect behavior defers the generation of the first interrupt.
The patch fixes the above-mentioned issue by setting the systick.tick
member and modifying the systick timer only if the ENABLE bit of
the SYSTICK Control and Status Register is set.
In addition, the Cortex-M3 Devices Generic User Guide mentioned that
"When ENABLE is set to 1, the counter loads the RELOAD value from the
SYST RVR register and then counts down". This patch adheres to the
statement of the user guide.

rocker: add new rocker switch device
Rocker is a simulated ethernet switch device. The device supports up to 62
front-panel ports and supports L2 switching and L3 routing functions, as well
as L2/L3/L4 ACLs. The device presents a single PCI device for each switch,
with a memory-mapped register space for device driver access.
Rocker device is invoked with -device, for example a 4-port switch:
-device rocker,name=sw1,len-ports=4,ports[0]=dev0,ports[1]=dev1, \
ports[2]=dev2,ports[3]=dev3
Each port is a netdev and can be paired with using -netdev id=<port name>.

rocker: add support for flow modification
We had support for flow add/del. This adds support for flow mod. I needed
this for L3 support where an existing route is modified using NLM_F_REPLACE.
For example:
ip route add 12.0.0.0/30 nexthop via 11.0.0.1 dev swp1
ip route change 12.0.0.0/30 nexthop via 11.0.0.9 dev swp2
The first cmd adds the route. The second cmd changes the existing route by
changing its nexthop info.
In the device, a mod operation results in the matching flow enty being modified
with the new settings. This is atomic to the device.

scripts: qmp-shell: Add verbose flag
Add a verbose flag that shows the QMP command that was
constructed, to allow for later copy/pasting, reference,
debugging, etc.
The QMP is converted from a Python literal to JSON first,
to ensure that it is viable input to the actual QMP parser.
As a side-effect, this JSON output will helpfully show all
the necessary conversions that were performed on the input,
illustrating that "True" was transformed back into "true",
literal values are now escaped with "" instead of '', and so on.

scripts: qmp-shell: add transaction subshell
Add a special processing mode to craft transactions.
By entering "transaction(" the shell will enter a special
mode where each subsequent command will be saved as a transaction
instead of executed as an individual command.
The transaction can be submitted by entering ")" on a line by itself.
Examples:
Separate lines:
(QEMU) transaction(
TRANS> block-dirty-bitmap-add node=drive0 name=bitmap1
TRANS> block-dirty-bitmap-clear node=drive0 name=bitmap0
TRANS> )
With a transaction action included on the first line:
(QEMU) transaction( block-dirty-bitmap-add node=drive0 name=bitmap2
TRANS> block-dirty-bitmap-add node=drive0 name=bitmap3
TRANS> )
As a one-liner, with just one transaction action:
(QEMU) transaction( block-dirty-bitmap-add node=drive0 name=bitmap0 )
As a side-effect of this patch, blank lines are now parsed as no-ops,
regardless of which shell mode you are in.

scripts: qmp-shell: Expand support for QMP expressions
This includes support for [] expressions, single-quotes in
QMP expressions (which is not strictly a part of JSON), and
the ability to use "True", "False" and "None" literals instead
of JSON's equivalent true, false, and null literals.
qmp-shell currently allows you to describe values as
JSON expressions:
key={"key":{"key2":"val"}}
But it does not currently support arrays, which are needed
for serializing and deserializing transactions:
key=[{"type":"drive-backup","data":{...}}]
qmp-shell also only currently accepts doubly quoted strings
as-per JSON spec, but QMP allows single quotes.
Lastly, python allows you to utilize "True" or "False" as
boolean literals, but JSON expects "true" or "false". Expand
qmp-shell to allow the user to type either, converting to the
correct type.
As a consequence of the above, the key=val parsing is also improved
to give better error messages if a key=val token is not provided.
CAVEAT: The parser is still extremely rudimentary and does not
expect to find spaces in {} nor [] expressions. This patch does
not improve this functionality.

MAINTAINERS: New maintainer for QMP and QAPI
Markus is taking over maintership of QMP and the QAPI from
me. Markus has always been a great reviewer and contributor
to those subsystems. In the last few months he's also doing
pull requests that are a lot more relevant than the ones I
was able to do. So, this is a natural move.
I'm still the maintainer of HMP and QObjects, but I'm
looking for someone to take over those too.

json-parser: Accept 'null' in QMP
We document that in QMP, the client may send any json-value
for the optional "id" key, and then return that same value
on reply (both success and failures, insofar as the failure
happened after parsing the id). [Note that the output may
not be identical to the input, as whitespace may change and
since we may reorder keys within a json-object, but that this
still constitutes the same json-value]. However, we were not
handling the JSON literal null, which counts as a json-value
per RFC 7159.
Also, down the road, given the QAPI schema of {'*foo':'str'} or
{'*foo':'ComplexType'}, we could decide to allow the QMP client
to pass { "foo":null } instead of the current representation of
{ } where omitting the key is the only way to get at the default
NULL value. Such a change might be useful for argument
introspection (if a type in older qemu lacks 'foo' altogether,
then an explicit "foo":null probe will force an easily
distinguished error message for whether the optional "foo" key
is even understood in newer qemu). And if we add default values
to optional arguments, allowing an explicit null would be
required for getting a NULL value associated with an optional
string that has a non-null default. But all that can come at a
later day.
The 'check-unit' testsuite is enhanced to test that parsing
produces the same object as explicitly requesting a reference
to the special qnull object. In addition, I tested with:
$ ./x86_64-softmmu/qemu-system-x86_64 -qmp stdio -nodefaults
{"QMP": {"version": {"qemu": {"micro": 91, "minor": 2, "major": 2}, "package": ""}, "capabilities": []}}
{"execute":"qmp_capabilities","id":null}
{"return": {}, "id": null}
{"id":{"a":null,"b":[1,null]},"execute":"quit"}
{"return": {}, "id": {"a": null, "b": [1, null]}}
{"timestamp": {"seconds": 1427742379, "microseconds": 423128}, "event": "SHUTDOWN"}

qobject: Add a special null QObject
I'm going to fix the JSON parser to recognize null. The obvious
representation of JSON null as (QObject *)NULL doesn't work, because
the parser already uses it as an error value. Perhaps we should
change it to free NULL for null, but that's more than I can do right
now. Create a special null QObject instead.
The existing QDict, QList, and QString all represent something that
is a pointer in C and could therefore be associated with NULL. But
right now, all three of these sub-types are always non-null once
created, so the new null sentinel object is intentionally unrelated
to them.

qemu-nbd: only send a limited number of errno codes on the wire
Right now, NBD includes potentially platform-specific error values in
the wire protocol.
Luckily, most common error values are more or less universal: in
particular, of all errno values <= 34 (up to ERANGE), they are all the
same on supported platforms except for 11 (which is EAGAIN on Windows and
Linux, but EDEADLK on Darwin and the *BSDs). So, in order to guarantee
some portability, only keep a handful of possible error codes and squash
everything else to EINVAL.
This patch defines a limited set of errno values that are valid for the
NBD protocol, and specifies recommendations for what error to return
in specific corner cases. The set of errno values is roughly based on
the errors listed in the read(2) and write(2) man pages, with some
exceptions:
- ENOMEM is added for servers that implement copy-on-write or other
formats that require dynamic allocation.
- EDQUOT is not part of the universal set of errors; it can be changed
to ENOSPC on the wire format.
- EFBIG is part of the universal set of errors, but it is also changed
to ENOSPC because it is pretty similar to ENOSPC or EDQUOT.
Incoming values will in general match system errno values, but not
on the Hurd which has different errno values (they have a "subsystem
code" equal to 0x10 in bits 24-31). The Hurd is probably not something
to which QEMU has been ported, but still do the right thing and
reverse-map the NBD errno values to the system errno values.
The corresponding patch to the NBD protocol description can be found at
http://article.gmane.org/gmane.linux.drivers.nbd.general/3154.

rules.mak: Force CFLAGS for all objects in DSO
Because of the trick of process-archive-undefs, all .mo objects, even
with --enable-modules, are dependencies of executables.
This breaks CFLAGS propogation because the compiling of module object
will happen too early before building for DSO.
With GCC 5, the linking would fail because .o doesn't have -fPIC. Also,
BUILD_DSO will be missed. (module-common.o will have it, so the stamp
symbol was still liked in .so).
Fix the problem by forcing the CFLAGS on individual .o-cflags during
unnest-vars.

usb: fix usb-net segfault
The dev->config pointer isn't set until guest
system initializes usb devices (via
usb_desc_set_config). However qemu networking can
go through some motions prior to that, e.g.:
#0 is_rndis (s=0x555557261970) at hw/usb/dev-network.c:653
#1 0x000055555585f723 in usbnet_can_receive (nc=0x55555641e820) at hw/usb/dev-network.c:1315
#2 0x000055555587635e in qemu_can_send_packet (sender=0x5555572660a0) at net/net.c:470
#3 0x0000555555878e34 in net_hub_port_can_receive (nc=0x5555562d7800) at net/hub.c:101
#4 0x000055555587635e in qemu_can_send_packet (sender=0x5555562d7980) at net/net.c:470
#5 0x000055555587dbca in tap_can_send (opaque=0x5555562d7980) at net/tap.c:172
The command to reproduce most reliably was:
qemu-system-i386 -usb -device usb-net,vlan=0 -net tap,vlan=0
This wasn't strictly a problem with tap. Other
networking endpoints (vde, user) could trigger
this problem as well.

s390x/kvm: use ioctl KVM_S390_IRQ for vcpu interrupts
KVM_S390_INT uses only two parameter fields. This is not
enough to pass all required information for certain interrupts.
A new ioctl KVM_S390_IRQ is available which allows us to
inject all local interrupts as defined in the Principles of
Operation. It takes a struct kvm_s390_irq as a parameter
which can store interrupt payload data for all interrupts.
Let's use the new ioctl for injecting vcpu interrupts.

virtio-ccw: change realization sequence
virtio-ccw has an odd sequence of realizing devices: first the
device-specific relization (net, block, ...), then the generic
realization. It feels less odd to have the generic realization
callback trigger the device-specific realization instead (and this
also matches what virtio-pci does).
One thing to note: We need to defer initializing the cu model in the
sense id data until after the device-specific realization has been
performed, as we need to refer to the virtio device's device_id.

s390-virtio: clear {used,avail}_event_idx on reset as well
The old s390-virtio transport clears the vring used/avail indices in
the shared area on reset. When we enabled event_idx for virtio-blk, we
noticed that this is not enough: We also need to clear the published
used/avail event indices, or reboot will fail.

s390-virtio: use common features
We used to avoid enabling event_idx for virtio-blk devices via
s390-virtio, but we now have a workaround in place for guests trying
to use the device before setting DRIVER_OK. Therefore, let's add
DEFINE_VIRTIO_COMMON_FEATURES to the base device so all devices get
those common features - and make s390-virtio use the same mechanism
as the other transports do.

s390-virtio: Accommodate guests using virtqueues too early
Feature updates are not a synchronuous operation for the legacy
s390-virtio transport. This transport syncs the guest feature bits
(those from finalize) on the set_status hypercall. Before that qemu
thinks that features are zero, which means QEMU will misbehave, e.g.
it will not write the event index, even if the guest asks for it.
Let's detect the case where a kick happens before the driver is ready
and force sync the features.
With this workaround, it is now safe to switch to the common feature
bit handling code as used by all other transports.

qapi: Check for member name conflicts with a base class
Our type inheritance for both 'struct' and for flat 'union' merges
key/value pairs from the base class with those from the type in
question. Although the C code currently boxes things so that there
is a distinction between which member is referred to, the QMP wire
format does not allow passing a key more than once in a single
object. Besides, if we ever change the generated C code to not be
quite so boxy, we'd want to avoid duplicate member names there,
too.
Fix a testsuite entry added in an earlier patch, as well as adding
a couple more tests to ensure we have appropriate coverage. Ensure
that collisions are detected, regardless of whether there is a
difference in opinion on whether the member name is optional.

qapi: Support (subset of) \u escapes in strings
The handling of \ inside QAPI strings was less than ideal, and
really only worked JSON's \/, \\, \", and our extension of \'
(an obvious extension, when you realize we use '' instead of ""
for strings). For other things, like '\n', it resulted in a
literal 'n' instead of a newline.
Of course, at the moment, we really have no use for escaped
characters, as QAPI has to map to C identifiers, and we currently
support ASCII only for that. But down the road, we may add
support for default values for string parameters to a command
or struct; if that happens, it would be nice to correctly support
all JSON escape sequences, such as \n or \uXXXX. This gets us
closer, by supporting Unicode escapes in the ASCII range.
Since JSON does not require \OCTAL or \xXX escapes, and our QMP
implementation does not understand them either, I intentionally
reject it here, but it would be an easy addition if we desired it.
Likewise, intentionally refusing the NUL byte means we don't have
to worry about C strings being shorter than the qapi input.

A future patch will be using a 'name':{dictionary} entry in the
QAPI schema to specify a default value for an optional argument
(see previous commit message for more details why); but existing
use of inline nested structs conflicts with that goal. This patch
fixes one of only two commands relying on nested types, by
breaking the nesting into an explicit type; it means that the
type is now boxed instead of unboxed in C code, but the QMP wire
format is unaffected by this change.
Prefer the safer g_new0() while making the conversion, and reduce
some long lines.

qapi: Drop inline nested struct in query-version
A future patch will be using a 'name':{dictionary} entry in the
QAPI schema to specify a default value for an optional argument
(see previous commit message for more details why); but existing
use of inline nested structs conflicts with that goal. This patch
fixes one of only two commands relying on nested types, by
breaking the nesting into an explicit type; it means that the
type is now boxed instead of unboxed in C code, but the QMP wire
format is unaffected by this change.
Prefer the safer g_new0() while making the conversion.

qapi: Drop tests for inline nested structs
A future patch will be using a 'name':{dictionary} entry in the
QAPI schema to specify a default value for an optional argument;
but existing use of inline nested structs conflicts with that goal.
More precisely, a definition in the QAPI schema associates a name
with a set of properties:
Example 1: { 'struct': 'Foo', 'data': { MEMBERS... } }
associates the global name 'Foo' with properties (meta-type struct)
and MEMBERS...
Example 2: 'mumble': TYPE
within MEMBERS... above associates 'mumble' with properties (type
TYPE) and (optional false) within type Foo
The syntax of example 1 is extensible; if we need another property,
we add another name/value pair to the dictionary (such as
'base':TYPE). The syntax of example 2 is not extensible, because
the right hand side can only be a type.
We have used name encoding to add a property: "'*mumble': 'int'"
associates 'mumble' with (type int) and (optional true). Nice,
but doesn't scale. So the solution is to change our existing uses
to be syntactic sugar to an extensible form:
NAME: TYPE --> NAME: { 'type': TYPE, 'optional': false }
*ONAME: TYPE --> ONAME: { 'type': TYPE, 'optional': true }
This patch fixes the testsuite to avoid inline nested types, by
breaking the nesting into explicit types; it means that the type
is now boxed instead of unboxed in C code, but makes no difference
on the wire (and if desired, a later patch could change the
generator to not do so much boxing in C). When touching code to
add new allocations, also convert existing allocations to
consistently prefer typesafe g_new0 over g_malloc0 when a type
name is involved.

qapi: Merge UserDefTwo and UserDefNested in tests
In the testsuite, UserDefTwo and UserDefNested were identical
structs other than the member names. Reduce code duplication by
having just one type, and choose names that also favor reuse.
This will also make it easier for a later patch to get rid of
inline nested types in QAPI. When touching code related to

g_new0(Type, 1).

Referring to "type" as both a meta-type (built-in, enum, union,
alternate, or struct) and a specific type (the name that the
schema uses for declaring structs) is confusing. The confusion
is only made worse by the fact that the generator mostly already

accepting the existing .json files as-is, so that the meat of

Fix the testsuite fallout for error messages that change, and
in some cases, become more legible. Improve comments to better
match our intentions where a struct (rather than any complex
type) is required. Note that in some cases, an error message
now refers to 'struct' while the schema still refers to 'type';
that will be cleaned up in the later commit to the schema.

qapi: More rigorous checking for type safety bypass
Now that we have a way to validate every type, we can also be
stricter about enforcing that callers that want to bypass
type safety in generated code. Prior to this patch, it didn't
matter what value was associated with the key 'gen', but it
looked odd that 'gen':'yes' could result in bypassing the
generated code. These changes also enforce the changes made
earlier in the series for documentation and consolidation of
using '**' as the wildcard type, as well as 'gen':false as the
canonical spelling for requesting type bypass.
Note that 'gen':false is a one-way switch away from the default;
we do not support 'gen':true (similar for 'success-response').
In practice, this doesn't matter.

qapi: Whitelist commands that don't return dictionary
...or an array of dictionaries. Although we have to cater to
existing commands, returning a non-dictionary means the command
is not extensible (no new name/value pairs can be added if more
information must be returned in parallel). By making the
whitelist explicit, any new command that falls foul of this
practice will have to be self-documenting, which will encourage
developers to either justify the action or rework the design to
use a dictionary after all.
It's a little bit sloppy that we share a single whitelist among
three clients (it's too permissive for each). If this is a
problem, a future patch could tighten things by having the
generator take the whitelist as an argument (as in
scripts/qapi-commands.py --legacy-returns=...), or by having
the generator output C code that requires explicit use of the
whitelist (as in:
#ifndef FROBNICATE_LEGACY_RETURN_OK
# error Command 'frobnicate' should return a dictionary
#endif
then having the callers define appropriate macros). But until
we need such fine-grained separation (if ever), this patch does
the job just fine.

qapi: Require valid names
Previous commits demonstrated that the generator overlooked various
bad naming situations:
- types, commands, and events need a valid name
- enum members must be valid names, when combined with prefix
- union and alternate branches cannot be marked optional
Valid upstream names match [a-zA-Z][a-zA-Z0-9_-]*; valid downstream
names match __[a-zA-Z][a-zA-Z0-9._-]*. Enumerations match the
weaker [a-zA-Z0-9._-]+ (in part thanks to QKeyCode picking an enum
that starts with a digit, which we can't change now due to
backwards compatibility). Rather than call out three separate
regex, this patch just uses a broader combination that allows both
upstream and downstream names, as well as a small hack that
realizes that any enum name is merely a suffix to an already valid
name prefix (that is, any enum name is valid if prepending _ fits
the normal rules).
We could reject new enumeration names beginning with a digit by
whitelisting existing exceptions. We could also be stricter
about the distinction between upstream names (no leading
underscore, no use of dot) and downstream (mandatory leading
double underscore), but it is probably not worth the bother.

Most of the new tests focus on blatant errors. But
returns-whitelist is a case where we have historically allowed
returning something other than a JSON object from particular
commands; we have to keep that behavior to avoid breaking clients,
but it would be nicer to avoid adding such commands in the future,
because any return that is not an (array of) object cannot be
easily extended if future qemu wants to return additional
information. The QMP protocol already documents that clients
should ignore unknown dictionary keys, but does not require
clients to have to handle more than one type of JSON object.

qapi: Unify type bypass and add tests
For a few QMP commands, we are forced to pass an arbitrary type
without tracking it properly in QAPI. Among the existing clients,
this unnamed type was spelled 'dict', 'visitor', and '**'; this
patch standardizes on '**', matching the documentation changes
earlier in the series.
Meanwhile, for the 'gen' key, we have been ignoring the value,
although the schema consistently used "'no'" ('success-response'
was hard-coded to checking for 'no'). But now that we can support
a literal "false" in the schema, we might as well use that rather
than ignoring the value or special-casing a random string. Note
that these are one-way switches (use of 'gen':true is not the same
as omitting 'gen'). Also, the use of '**' requires 'gen':false,
but the use of 'gen':false does not mandate the use of '**'.
There is no difference to the generated code. Add some tests on
what we'd like to guarantee, although it will take later patches
to clean up test results and actually enforce the use of a bool
parameter.

qapi: Better error messages for duplicated expressions

- a complex type or command reusing a built-in type name
- redeclaration of a type name, whether by the same or different
metatype
- redeclaration of a command or event
- collision of a type with implicit 'Kind' enum for a union
- collision with an implicit MAX enum constant
Since the c_type() function in the generator treats all names
as being in the same namespace, this patch adds a global array
to track all known names and their source, to prevent collisions
before it can cause further problems. While valid .json files
won't trigger any of these cases, we might as well be nicer to

qapi: Better error messages for bad expressions
The previous commit demonstrated that the generator overlooked some
fairly basic broken expressions:
- missing metataype
- metatype key has a non-string value
- unknown key in relation to the metatype
- conflicting metatype (this patch treats the second metatype as an
unknown key of the first key visited, which is not necessarily the
first key the user typed)
Add check_keys to cover these situations, and update testcases to
match. A couple other tests (enum-missing-data, indented-expr) had
to change since the validation added here occurs so early.
Conversely, changes to ident-with-escape results show that we still
have problems where our handling of escape sequences differs from
true JSON, which will matter down the road if we allow arbitrary
default string values for optional parameters (but for now is not
too bad, as we currently can avoid unicode escaping as we don't
need to represent anything beyond C identifier material).
While valid .json files won't trigger any of these cases, we might
as well be nicer to developers that make a typo while trying to add

qapi: Add some union tests
Demonstrate that the qapi generator doesn't deal well with unions
that aren't up to par. Later patches will update the expected
reseults as the generator is made stricter. A few tests work
as planned, but most show poor or missing error messages.
Of particular note, qapi-code-gen.txt documents 'base' only for
flat unions, but the tests here demonstrate that we currently allow
a 'base' to a simple union, although it is exercised only in the
testsuite. Later patches will remove this undocumented feature, to
give us more flexibility in adding other future extensions to union
types. For example, one possible extension is the idea of a
type-safe simple enum, where added fields tie the discriminator to
a user-defined enum type rather than creating an implicit enum from
the names in 'data'. But adding such safety on top of a simple
enum with a base type could look ambiguous with a flat enum;
besides, the documentation also mentions how any simple union can
be represented by an equivalent flat union. So it will be simpler
to just outlaw support for something we aren't using.

qapi: Better error messages for bad enums
The previous commit demonstrated that the generator had several
flaws with less-than-perfect enums:
- an enum that listed the same string twice (or two variant
strings that map to the same C enumerator) ended up generating
an invalid C enum
- because the generator adds a _MAX terminator to each enum,
the use of an enum member 'max' can also cause this clash
- if an enum omits 'data', the generator left a python stack
trace rather than a graceful message
- an enum that used a non-array 'data' was silently accepted by
the parser
- an enum that used non-string members in the 'data' member
was silently accepted by the parser
Add check_enum to cover these situations, and update testcases
to match. While valid .json files won't trigger any of these
cases, we might as well be nicer to developers that make a typo
while trying to add new QAPI code.

qapi: Require ASCII in schema
Python 2 and Python 3 have a wild history of whether strings
default to ascii or unicode, where Python 3 requires checking
isinstance(foo, basestr) to cover all strings, but where that
code is not portable to Python 2. It's simpler to just state
that we don't care about Unicode strings, and to just always
use the simpler isinstance(foo, str) everywhere.
I'm no python expert, so I'm basing it on this conversation:

qapi: Add copyright declaration on docs
While our top-level COPYING with its GPLv2+ license applies to
any documentation file that omits explicit instructions, these
days it's better to be a good example of calling out our
intentions. Correct use of GPL requires the use of a copyright
statement, so I'm adding notice to two QAPI documents, by
attributing these files to the initial authors and major
contributors. I used:
$ git blame --line-porcelain $file \
| sed -n 's/^author //p' | sort | uniq -c | sort -rn
to determine authorship of these two files. qmp-spec.txt blames
entirely to Red Hat (easy, since my contribution falls in that
category); while qapi-code-gen.txt has multiple contributors
representing multiple entities. But since it was originally
supplied by Michael Roth, the notice I added there copies the
notice he has used in other files. As there is no intended
change in license from the implicit one previously present from
the top level, I have not bothered to CC other contributors;
if we want to weaken things to something looser (such as LGPL)
so that there is no question that someone re-implementing the
spec is not forced to use GPL, that would be a different commit.

tcg: optimise memory layout of TCGTemp
This brings down the size of the struct from 56 to 32 bytes on 64-bit,
and to 20 bytes on 32-bit. This leads to memory savings:

Note that using an entire byte for some enums that need less than
that wastes a few bits (noticeable in 32 bits, where we use
20 bytes instead of 16) but avoids extraction code, which overall
is a win--I've tested several variations of the patch, and the appended
is the best performer for OpenSSL's bntest by a very small margin:

Enable NVMe start controller for Windows guest.
Windows seems to send two separate calls to NVMe controller configuration. The
first sends configuration info and the second the enable bit. I couldn't
enable the Windows 8.1 in-box NVMe driver with base Qemu. I made the
following change to store the configuration data and then handle enable and
NVMe driver works on Windows 8.1.
I am not a Windows expert and I'm not entirely sure this is the correct
approach. I'm offering it for anyone who wishes to use NVMe on Windows 8.1
using Qemu.
I have tested this change with Linux and Windows guests with NVMe devices.

kvm: better advice for failed s390x startup
If KVM_CREATE failed on s390x, we print a hint to enable the switch_amode
kernel parameter. This only applies to old kernels, and only if the
error was -EINVAL. Moreover, with new kernels, the most likely reason
for -EINVAL is that pgstes were not enabled.
Let's update the error message to give a better hint on where things
may need fixing.

s390x/kvm: Support access register mode for KVM_S390_MEM_OP ioctl
Access register mode is one of the modes that control dynamic address
translation. In this mode the address space is specified by values of
the access registers. The effective address-space-control element is
obtained from the result of the access register translation. See
the "Access-Register Introduction" section of the chapter 5 "Program
Execution" in "Principles of Operations" for more details.
When the CPU is in AR mode, the s390_cpu_virt_mem_rw() function must
know which access register number to use for address translation.
This patch does several things:
- add new parameter 'uint8_t ar' to that function
- decode ar number from intercepted instructions
- pass the ar number to s390_cpu_virt_mem_rw(), which in turn passes it
to the KVM_S390_MEM_OP ioctl.

s390x/kvm: Put vm name, extended name and UUID into STSI322 SYSIB
KVM prefills the SYSIB, returned by STSI 3.2.2. This patch allows
userspace to intercept execution, and fill in the values, that are
known to qemu: machine name (8 chars), extended machine name (256
chars), extended machine name encoding (equals 2 for UTF-8) and UUID.
STSI322 qemu handler also finds a highest virtualization level in
level-3 virtualization stack that doesn't support Extended Names
(Ext Name delimiter) and propagates zero Ext Name to all levels below,
because this level is not capable of managing Extended Names of lower
levels.

nbd/trivial: fix type cast for ioctl
This fixes ioctl behavior on powerpc e6500 platforms with 64bit kernel and 32bit
userspace. The current type cast has no effect there and the value passed to the
kernel is still 0. Probably an issue related to the compiler, since I'm assuming
the same configuration works on a similar setup on x86.
Also ensure consistency with previous type cast in TRACE message.

Makefile.target: prepend $libs_softmmu to $LIBS
I discovered a problem when trying to build QEMU statically with gcc.
libm is an element of LIBS while libpixman-1 is an element in
libs_softmmu. Libpixman references functions in libm, so the original
ordering makes linking fail.
This fix is to reorder $libs_softmmu and $LIBS to make -lm appear after
-lpixman-1. However I'm not quite sure if this is the right fix, hence
the RFC tag.
Normally QEMU is built with c++ compiler which happens to link in libm
(at least this is the case with g++), so building QEMU statically
normally just works and nobody notices this issue.

configure: Add support for tcmalloc
This adds "--enable-tcmalloc" and "--disable-tcmalloc" to allow linking
to libtcmalloc from gperftools.
tcmalloc is a malloc implementation that works well with threads and is
fast, so it is good for performance.
It is disabled by default, because the MALLOC_PERTURB_ flag we use in
tests doesn't work with tcmalloc. However we can enable tcmalloc
specific heap checker and profilers later.
An IOPS gain can be observed with virtio-blk-dataplane, other parts of
QEMU will directly benefit from it as well:

our primary mechanism for resetting graphics cards. The result is
that these devices typically work well for a single VM boot. If the
VM is rebooted or restarted, the guest driver is not able to init the
card from the dirty state, resulting in a blue screen for Windows
guests.
The workaround is to use a device specific reset. This is not 100%
reliable though since it depends on the incoming state of the device,
but it substantially improves the usability of these devices in a VM.

vfio-pci: Fix error path sign
This is an impossible error path due to the fact that we're reading a
kernel provided, rather than user provided link, which will certainly
always fit in PATH_MAX. Currently it returns a fixed 26 char path
plus %d group number, which typically maxes out at double digits.
However, the caller of the initfn certainly expects a less-than zero
return value on error, not just a non-zero value. Therefore we
should correct the sign here.

vfio-pci: Further fix BAR size overflow
In an analysis by Laszlo, the resulting type of our calculation for
the end of the MSI-X table, and thus the start of memory after the
table, is uint32_t. We're therefore not correctly preventing the
corner case overflow that we intended to fix here where a BAR >=4G
could place the MSI-X table to end exactly at the 4G boundary. The
MSI-X table offset is defined by the hardware spec to 32bits, so we
simply use a cast rather than changing data structure types. This
scenario is purely theoretically, typically the MSI-X table is located
at the front of the BAR.

virtio-scsi: Move DEFINE_VIRTIO_SCSI_FEATURES to virtio-scsi
So far virtio-scsi-device can't expose host features to guest while
using virtio-mmio because it doesn't set DEFINE_VIRTIO_SCSI_FEATURES on
backend or transport.
The host features belong to the backends while virtio-scsi-pci,
virtio-scsi-s390 and virtio-scsi-ccw set the DEFINE_VIRTIO_SCSI_FEATURES
on transports. But they already have the ability to forward property
accesses to the backend child. So if we move the host features to
backends, it doesn't break the backwards compatibility for them and
make host features work while using virtio-mmio.

transports just sync the host features from backends.

Since pci_nic_init() is only used by pci_nic_init_nofail(), the

iotests: add QMP event waiting queue
A filter is added to allow callers to request very specific
events to be pulled from the event queue, while leaving undesired
events still in the stream.
This allows us to poll for completion data for multiple asynchronous
events in any arbitrary order.
A new timeout context is added to the qmp pull_event method's
wait parameter to allow tests to fail if they do not complete
within some expected period of time.
Also fixed is a bug in qmp.pull_event where we try to retrieve an event
from an empty list if we attempt to retrieve an event with wait=False
but no events have occurred.

block: Add bitmap successors
A bitmap successor is an anonymous BdrvDirtyBitmap that is intended to
be created just prior to a sensitive operation (e.g. Incremental Backup)
that can either succeed or fail, but during the course of which we still
want a bitmap tracking writes.
On creating a successor, we "freeze" the parent bitmap which prevents
its deletion, enabling, anonymization, or creating a bitmap with the
same name.
On success, the parent bitmap can "abdicate" responsibility to the
successor, which will inherit its name. The successor will have been
tracking writes during the course of the backup operation. The parent
will be safely deleted.
On failure, we can "reclaim" the successor from the parent, unifying
them such that the resulting bitmap describes all writes occurring since
the last successful backup, for instance. Reclamation will thaw the
parent, but not explicitly re-enable it.
BdrvDirtyBitmap operations that target a single bitmap are protected
by assertions that the bitmap is not frozen and/or disabled.
BdrvDirtyBitmap operations that target a group of bitmaps, such as
bdrv_{set,reset}_dirty will ignore frozen/disabled drives with a
conditional instead.
Internal functions that enable/disable dirty bitmaps have assertions
added to them to prevent modifying frozen bitmaps.

A previous version of this patch added a QMP interface for changing

hbitmap: add hbitmap_merge
We add a bitmap merge operation to assist in error cases
where we wish to combine two bitmaps together.
This is algorithmically O(bits) provided HBITMAP_LEVELS remains
constant. For a full bitmap on a 64bit machine:
sum(bits/64^k, k, 0, HBITMAP_LEVELS) ~= 1.01587 * bits
We may be able to improve running speed for particularly sparse
bitmaps by using iterators, but the running time for dense maps
will be worse.
We present the simpler solution first, and we can refine it later
if needed.

hbitmap: cache array lengths
As a convenience: between incremental backups, bitmap migrations
and bitmap persistence we seem to need to recalculate these a lot.
Because the lengths are a little bit-twiddly, let's just solidly
cache them and be done with it.

qmp: Add block-dirty-bitmap-add and block-dirty-bitmap-remove
The new command pair is added to manage a user created dirty bitmap. The
dirty bitmap's name is mandatory and must be unique for the same device,
but different devices can have bitmaps with the same names.
The granularity is an optional field. If it is not specified, we will
choose a default granularity based on the cluster size if available,
clamped to between 4K and 64K to mirror how the 'mirror' code was
already choosing granularity. If we do not have cluster size info
available, we choose 64K. This code has been factored out into a helper
shared with block/mirror.
This patch also introduces the 'block_dirty_bitmap_lookup' helper,
which takes a device name and a dirty bitmap name and validates the
lookup, returning NULL and setting errp if there is a problem with
either field. This helper will be re-used in future patches in this
series.
The types added to block-core.json will be re-used in future patches
in this series, see:
'qapi: Add transaction support to block-dirty-bitmap-{add, enable, disable}'

qapi: Add optional field "name" to block dirty bitmap
This field will be set for user created dirty bitmap. Also pass in an
error pointer to bdrv_create_dirty_bitmap, so when a name is already
taken on this BDS, it can report an error message. This is not global
check, two BDSes can have dirty bitmap with a common name.
Implemented bdrv_find_dirty_bitmap to find a dirty bitmap by name, will
be used later when other QMP commands want to reference dirty bitmap by
name.
Add bdrv_dirty_bitmap_make_anon. This unsets the name of dirty bitmap.

qmp: fill in the image field in BlockDeviceInfo
The image field in BlockDeviceInfo is supposed to contain an ImageInfo
object. However that is being filled in by bdrv_query_info(), not by
bdrv_block_device_info(), which is where BlockDeviceInfo is actually
created.
Anyone calling bdrv_block_device_info() directly will get a null image
field. As a consequence of this, the HMP command 'info block -n -v'
crashes QEMU.
This patch moves the code that fills in that field from
bdrv_query_info() to bdrv_block_device_info().

There are several error messages that identify a BlockDriverState by

In those cases we should use bdrv_get_device_or_node_name() to fall
back to the node name and produce a more meaningful message. The

block: avoid unnecessary bottom halves
bdrv_aio_* APIs can use coroutines to achieve asynchronicity. However,
the coroutine may terminate without having yielded back to the caller
(for example because of something that invokes a nested event loop,
or because the coroutine is doing nothing at all). In this case,
the bdrv_aio_* API must delay the completion to the next iteration
of the main loop, because bdrv_aio_* will never invoke the callback
before returning.
This can be done with a bottom half, and indeed bdrv_aio_* is always
using one for simplicity. It is possible to gain some performance
(~3%) by avoiding this in the common case. A new field in the
BlockAIOCBCoroutine struct is set to true until the first time the
corotine has yielded to its creator, and completion goes through a
new function bdrv_co_complete. If the flag is false, bdrv_co_complete
invokes the callback immediately. If it is true, the caller will
notice that the coroutine has completed and schedule the bottom
half itself.

blockjob: Allow nested pause
This patch changes block_job_pause to increase the pause counter and
block_job_resume to decrease it.
The counter will allow calling block_job_pause/block_job_resume
unconditionally on a job when we need to suspend the IO temporarily.
From now on, each block_job_resume must be paired with a block_job_pause
to keep the counter balanced.
The user pause from QMP or HMP will only trigger block_job_pause once
until it's resumed, this is achieved by adding a user_paused flag in
BlockJob.
One occurrence of block_job_resume in mirror_complete is replaced with
block_job_enter which does what is necessary.
In block_job_cancel, the cancel flag is good enough to instruct
coroutines to quit loop, so use block_job_enter to replace the unpaired
block_job_resume.
Upon block job IO error, user is notified about the entering to the
pause state, so this pause belongs to user pause, set the flag
accordingly and expect a matching QMP resume.

thread-pool: clean up thread_pool_completion_bh()
This patch simplifies thread_pool_completion_bh().
The function first checks elem->state:
if (elem->state != THREAD_DONE) {
continue;
}
It then goes on to check elem->state == THREAD_DONE although we already
know this must be the case.
The QLIST_REMOVE() is duplicated down both branches of an if-else

qemu-img convert: Rewrite copying logic
The implementation of qemu-img convert is (a) messy, (b) buggy, and
(c) less efficient than possible. The changes required to beat some
sense into it are massive enough that incremental changes would only
make my and the reviewers' life harder. So throw it away and reimplement
it from scratch.
Let me give some examples what I mean by messy, buggy and inefficient:
(a) The copying logic of qemu-img convert has two separate branches for
compressed and normal target images, which roughly do the same -
except for a little code that handles actual differences between
compressed and uncompressed images, and much more code that
implements just a different set of optimisations and bugs. This is
unnecessary code duplication, and makes the code for compressed
output (unsurprisingly) suffer from bitrot.
The code for uncompressed ouput is run twice to count the the total
length for the progress bar. In the first run it just takes a
shortcut and runs only half the loop, and when it's done, it toggles
a boolean, jumps out of the loop with a backwards goto and starts
over. Works, but pretty is something different.
(b) Converting while keeping a backing file (-B option) is broken in
several ways. This includes not writing to the image file if the
input has zero clusters or data filled with zeros (ignoring that the
backing file will be visible instead).
It also doesn't correctly limit every iteration of the copy loop to
sectors of the same status so that too many sectors may be copied to
in the target image. For -B this gives an unexpected result, for
other images it just does more work than necessary.
Conversion with a compressed target completely ignores any target
backing file.
(c) qemu-img convert skips reading and writing an area if it knows from
metadata that copying isn't needed (except for the bug mentioned
above that ignores a status change in some cases). It does, however,
read from the source even if it knows that it will read zeros, and
then search for non-zero bytes in the read buffer, if it's possible
that a write might be needed.
This reimplementation of the copying core reorganises the code to remove
the duplication and have a much more obvious code flow, by essentially
splitting the copy iteration loop into three parts:
1. Find the number of contiguous sectors of the same status at the
current offset (This can also be called in a separate loop before the
copying loop in order to determine the total sectors for the progress
bar.)
2. Read sectors. If the status implies that there is no data there to
read (zero or unallocated cluster), don't do anything.
3. Write sectors depending on the status. If it's data, write it. If
we want the backing file to be visible (with -B), don't write it. If
it's zeroed, skip it if you can, otherwise use bdrv_write_zeroes() to
optimise the write at least where possible.

block: Switch to host monotonic clock for IO throttling
Currently, throttle timers won't make any progress when VCPU is not
running, which would stall the request queue in utils, qtest, vm
suspending, and live migration, without special handling.
Block jobs are confusingly inconsistent between with and without
throttling: if user sets a bps limit, stops the vm, then start a block
job, the block job will not make any progress; in contrary, if user
unsets the bps limit, or if it's not set, the block job will run
normally.
After this patch, with the host clock, even if the VCPUs are stopped,
the throttle queues will be processed.
This patch also enables potential to add throttle to bdrv_drain_all.
Currently all requests are drained immediately. In other words whenever
it is called, IO throttling goes ineffective (examples: system reset,
migration and many block job operations.). This is a loophole that guest
could exploit. If we use the host clock, we can later just trust the
nested poll. This could be done on top.
Note that for qemu-iotests case 093, which uses qtest, we still keep vm
clock so the script can control the clock stepping in order to be
deterministic.

bt-sdp: fix broken uuids power-of-2 calculation
The binary search in sdp_uuid_match() only works when the number of
elements to search is a power of two.
lo = record->uuid;
hi = record->uuids;
while (hi >>= 1)
if (lo[hi] <= val)
lo += hi;
return *lo == val;
I noticed that the record->uuids calculation in
sdp_service_record_build() was suspect:
record->uuids = 1 << ffs(record->uuids - 1);
Unlike most ffs(val) - 1 users, the expression is ffs(val - 1)!
Actually ffs() is the wrong function to use for power-of-2. Use
pow2ceil() to achieve the correct effect. Now the record->uuid[] array
is sized correctly and the binary search in sdp_uuid_match() should
work.
I'm not sure how to run/test this code.

pci: remove hard-coded bar size in msix_init_exclusive_bar()
This patch lets msix_init_exclusive_bar() can calculate the bar and
pba size based on the number of MSI-X vectors other than using a
hard-coded limit 4096. This is needed to allow device to have more
than 128 MSI_X vectors. To keep migration compatibility, keep using
4096 as bar size and 2048 for pba offset.
Notes: We don't care about the case that using vectors > 128 for
legacy machine type. Since we limit the queue max to 64, so vectors >=
65 is meaningless.
Virtio device will be the first user for this.

virtio-pci: speedup MSI-X masking and unmasking
This patch tries to speed up the MSI-X masking and unmasking through
the mapping between vector and queues. With this patch it will there's
no need to go through all possible virtqueues, which may help to
reduce the time spent when doing MSI-X masking/unmasking a single
vector when more than hundreds or even thousands of virtqueues were
supported.
Tested with 80 queue pairs virito-net-pci by changing the smp affinity
in the background and doing netperf in the same time:
Before the patch:
5711.70 Gbits/sec
After the patch:
6830.98 Gbits/sec
About 19.6% improvements in throughput.

virtio: introduce vector to virtqueues mapping
Currently we will try to traverse all virtqueues to find a subset that
using a specific vector. This is sub optimal when we will support
hundreds or even thousands of virtqueues. So this patch introduces a
method which could be used by transport to get all virtqueues that
using a same vector. This is done through QLISTs and the number of
QLISTs was queried through a transport specific method. When guest
setting vectors, the virtqueue will be linked and helpers for traverse
the list was also introduced.
The first user will be virtio pci which will use this to speed up
MSI-X masking and unmasking handling.

exec: Respect as_translate_internal length clamp
address_space_translate_internal will clamp the *plen length argument
based on the size of the memory region being queried. The iommu walker
logic in addresss_space_translate was ignoring this by discarding the
post fn call value of *plen. Fix by just always using *plen as the
length argument throughout the fn, removing the len local variable.
This fixes a bootloader bug when a single elf section spans multiple
QEMU memory regions.

ioport: reserve the whole range of an I/O port in the AddressSpace
When an I/O port is more than 1 byte long, ioport.c is currently
creating "short" regions, for example 0x1ce-0x1ce for the 16-bit
Bochs index port. When I/O ports are memory mapped, and thus
accessed via a subpage_ops memory region, subpage_accepts gets
confused because it finds a hole at 0x1cf and rejects the access.
In order to fix this, modify registration of the region to cover
the whole size of the I/O port. Attempts to access an invalid
port will be blocked by find_portio returning NULL.
This only affects the VBE DISPI regions. For all other cases,
the MemoryRegionPortio entries for 2- or 4-byte accesses overlap
an entry for 1-byte accesses, thus the size of the memory region
is not affected.

ioport: loosen assertions on emulation of 16-bit ports
Right now, ioport.c assumes that the entire range specified with
MemoryRegionPortio includes a region with size == 1. This however
is not true for the VBE DISPI ports, which are 16-bit only. The
next patch will make these regions' length equal to two, which can
cause the assertions to trigger. Replace them with simple conditionals.
Also, ioport.c will emulate a 16-bit ioport with two distinct reads
or writes, even if one of the two accesses is out of the bounds given
by the MemoryRegionPortio array. Do not do this anymore, instead
discard writes to the incorrect register and read it as all-ones.
This ensures that the mrp->read and mrp->write callbacks get an
in-range ioport number.

monitor: Make client_migrate_info synchronous
Live migration with spice works like this today:
(1) client_migrate_info monitor cmd
(2) spice server notifies client, client connects to target host.
(3) qemu waits until spice client connect is finished.
(4) send over vmstate (i.e. main part of live migration).
(5) spice handover to target host.
(3) is implemented by making client_migrate_info a async monitor
command. This is the only async monitor command we have.
The original reason to implement this dance was that qemu did not accept
new tcp connections while the incoming migration was running, so (2) and
(4) could not be done in parallel. That issue was fixed long ago though.
Qemu version 1.3.0 (released Dec 2012) and newer happily accept tcp
connects while the incoming migration runs.
Time to drop step (3). This patch does exactly that, by making the
monitor command synchronous and removing the code needed to handle the
async monitor command in ui/spice-core.c

exec.c: Capture the memory attributes for a watchpoint hit
Capture the memory attributes for the transaction which triggered
a watchpoint; this allows CPU specific code to implement features
like ARM's "user-mode only WPs also hit for LDRT/STRT accesses
made from privileged code". This change also correctly passes
through the memory attributes to the underlying device when
a watchpoint access doesn't hit.

Rather than retaining io_mem_read/write as simple wrappers around

memory: Define API for MemoryRegionOps to take attrs and return status
Define an API so that devices can register MemoryRegionOps whose read
and write callback functions are passed an arbitrary pointer to some
transaction attributes and can return a success-or-failure status code.
This will allow us to model devices which:
* behave differently for ARM Secure/NonSecure memory accesses
* behave differently for privileged/unprivileged accesses
* may return a transaction failure (causing a guest exception)
for erroneous accesses
This patch defines the new API and plumbs the attributes parameter through
to the memory.c public level functions io_mem_read() and io_mem_write(),
where it is currently dummied out.
The success/failure response indication is also propagated out to
io_mem_read() and io_mem_write(), which retain the old-style
boolean true-for-error return.

qmp: Give saner messages related to qmp_capabilities misuse
Pretending that QMP doesn't understand a command merely because
we are not in the right mode doesn't help first-time users figure

QMP calls out capabilities negotiation, we should also make it
clear in our error messages what we were expecting. With this

qmp-commands: fix incorrect uses of ":O" specifier
As far as the QMP parser is concerned, neither the 'O' nor the 'q' format specifiers
put any constraint on the command. However, there are two differences:
1) from a documentation point of view 'O' says that this command takes
a dictionary. The dictionary will be converted to QemuOpts in the
handler to match the corresponding HMP command.
2) 'O' sets QMP_ACCEPT_UNKNOWNS, resulting in the command accepting invalid
extra arguments. For example the following is accepted:
{ "execute": "send-key",
"arguments": { "keys": [ { "type": "qcode", "data": "ctrl" },
{ "type": "qcode", "data": "alt" },
{ "type": "qcode", "data": "delete" } ], "foo": "bar" } }
Neither send-key nor migrate-set-capabilities take a QemuOpts-like
dictionary; they take an array of dictionaries. And neither command
really wants to have extra unknown arguments. Thus, the right
specifier to use in this case is 'q'; with this patch the above
command fails with
{"error": {"class": "GenericError", "desc": "Invalid parameter 'foo'"}}
as intended.

hmp: fix crash in 'info block -n -v'
The image field in BlockDeviceInfo should never be null, however
bdrv_block_device_info() is not filling it in.
This makes the 'info block -n -v' command crash QEMU.
The proper solution is probably to move the relevant code from
bdrv_query_info() to bdrv_block_device_info(), but since we're too
close to the release for that this simpler workaround solves the
crash.

target-ppc: don't invalidate msr MSR_HVB bit in cpu_post_load
The invalidation code introduced in commit 2360b works by inverting most bits
of env->msr to ensure that hreg_store_msr() will forcibly update the CPU env
state to reflect the new msr value post-migration. Unfortunately
hreg_store_msr() is called with alter_hv set to 0 which preserves the MSR_HVB
state from the CPU env which is now the opposite value to what it should be.
Ensure that we don't invalidate the msr MSR_HVB bit during cpu_post_load so
that the correct value is restored. This fixes suspend/resume for PPC64.

Commit 0b183fc871:"memory: move mem_path handling to
memory_region_allocate_system_memory" split memory_region_init_ram and
memory_region_init_ram_from_file. Also it moved mem-path handling a step

Therefore for any board that uses memory_region_init_ram directly,
-mem-path is not supported.
Fix this by replacing memory_region_init_ram with
memory_region_allocate_system_memory.

tcg/tcg-op.c: Fix ld/st of 64 bit values on 32-bit bigendian hosts
Commit 951c6300f7 out-of-lined the 32-bit-host versions of
tcg_gen_{ld,st}_i64, but in the process it inadvertently changed
an #ifdef HOST_WORDS_BIGENDIAN to #ifdef TCG_TARGET_WORDS_BIGENDIAN.
Since the latter doesn't get defined anywhere this meant we always
took the "LE host" codepath, and stored the two halves of the value
in the wrong order on BE hosts. This typically breaks any 64-bit
guest on a 32-bit BE host completely, and will have possibly more
subtle effects even for 32-bit guests.
Switch the ifdef back to HOST_WORDS_BIGENDIAN.

block/iscsi: handle zero events from iscsi_which_events
newer libiscsi versions may return zero events from iscsi_which_events.
In this case iscsi_service will return immediately without any progress.
To avoid busy waiting for iscsi_which_events to change we deregister all
read and write handlers in this case and schedule a timer to periodically
check iscsi_which_events for changed events.
Next libiscsi version will introduce async reconnects and zero events
are returned while libiscsi is waiting for a reconnect retry.

aio: strengthen memory barriers for bottom half scheduling
There are two problems with memory barriers in async.c. The fix is
to use atomic_xchg in order to achieve sequential consistency between
the scheduling of a bottom half and the corresponding execution.
First, if bh->scheduled is already 1 in qemu_bh_schedule, QEMU does
not execute a memory barrier to order any writes needed by the callback
before the read of bh->scheduled. If the other side sees req->state as
THREAD_ACTIVE, the callback is not invoked and you get deadlock.
Second, the memory barrier in aio_bh_poll is too weak. Without this
patch, it is possible that bh->scheduled = 0 is not "published" until
after the callback has returned. Another thread wants to schedule the
bottom half, but it sees bh->scheduled = 1 and does nothing. This causes
a lost wakeup. The memory barrier should have been changed to smp_mb()
in commit 924fe12 (aio: fix qemu_bh_schedule() bh->ctx race condition,
2014-06-03) together with qemu_bh_schedule()'s. Guess who reviewed
that patch?
Both of these involve a store and a load, so they are reproducible on
x86_64 as well. It is however much easier on aarch64, where the
libguestfs test suite triggers the bug fairly easily. Even there the
failure can go away or appear depending on compiler optimization level,
tracing options, or even kernel debugging options.
Paul Leveille however reported how to trigger the problem within 15
minutes on x86_64 as well. His (untested) recipe, reproduced here
for reference, is the following:
1) Qcow2 (or 3) is critical – raw files alone seem to avoid the problem.
2) Use “cache=directsync” rather than the default of
“cache=none” to make it happen easier.
3) Use a server with a write-back RAID controller to allow for rapid
IO rates.
4) Run a random-access load that (mostly) writes chunks to various
files on the virtual block device.
a. I use ‘diskload.exe c:25’, a Microsoft HCT load
generator, on Windows VMs.
b. Iometer can probably be configured to generate a similar load.
5) Run multiple VMs in parallel, against the same storage device,
to shake the failure out sooner.
6) IvyBridge and Haswell processors for certain; not sure about others.
A similar patch survived over 12 hours of testing, where an unpatched
QEMU would fail within 15 minutes.
This bug is, most likely, also the cause of failures in the libguestfs
testsuite on AArch64.
Thanks to Laszlo Ersek for initially reporting this bug, to Stefan
Hajnoczi for suggesting closer examination of qemu_bh_schedule, and to
Paul for providing test input and a prototype patch.

virtio-blk: correctly dirty guest memory
After qemu_iovec_destroy, the QEMUIOVector's size is zeroed and
the zero size ultimately is used to compute virtqueue_push's len
argument. Therefore, reads from virtio-blk devices did not
migrate their results correctly. (Writes were okay).
Save the size in virtio_blk_handle_request, and use it when the request
is completed.

qcow2: Fix header update with overridden backing file
In recent qemu versions, it is possible to override the backing file
name and format that is stored in the image file with values given at
runtime. In such cases, the temporary override could end up in the
image header if the qcow2 header was updated, while obviously correct
behaviour would be to leave the on-disk backing file path/format
unchanged.

sysbus: Make devices picking up backends unavailable with -device
Device models aren't supposed to go on fishing expeditions for
backends. They should expose suitable properties for the user to set.
For onboard devices, board code sets them.
A number of sysbus devices pick up block backends in their init() /
instance_init() methods with drive_get_next() instead: sl-nand,
milkymist-memcard, pl181, generic-sdhci.
Likewise, a number of sysbus devices pick up character backends in
their init() / realize() methods with qemu_char_get_next_serial():
cadence_uart, digic-uart, etraxfs,serial, lm32-juart, lm32-uart,
milkymist-uart, pl011, stm32f2xx-usart, xlnx.xps-uartlite.
All these mistakes are already marked FIXME. See the commit that
added these FIXMEs for a more detailed explanation of what's wrong.
Fortunately, only machines ppce500 and pseries-* support -device with
sysbus devices, and none of the devices above is supported with these
machines.
Set cannot_instantiate_with_device_add_yet to preserve our luck.

We can't fix this in time for the release, but since the device is new
in 2.3, we can set cannot_instantiate_with_device_add_yet to disable
it before this mistake becomes ABI, and we have to support command
lines like

hw: Mark device misusing nd_table[] FIXME
NICs defined with -net nic are for board initialization to wire up.
Board code examines nd_table[] to find them, and creates devices with
their qdev NIC properties set accordingly.
Except "allwinner-a10" goes on a fishing expedition for NIC
configuration instead of exposing the usual NIC properties for board
code to set: it uses nd_table[0] in its instance_init() method.
Picking up the first -net nic option's configuration that way works
when the device is created by board code. But it's inappropriate for
-device and device_add. Not only is it inconsistent with how the
other block device models work (they get their configuration from
properties "mac", "vlan", "netdev"), it breaks when nd_table[0] has
been picked up by the board or a previous -device / device_add
already.
Example:
$ qemu-system-arm -S -M cubieboard -device allwinner-a10
qemu-system-arm: -device allwinner-a10: Property 'allwinner-emac.netdev' can't take value 'hub0port0', it's in use
Aborted (core dumped)
It also breaks in other entertaining ways:
$ qemu-system-arm -M highbank -device allwinner-a10
qemu-system-arm: -device allwinner-a10: Unsupported NIC model: xgmac
$ qemu-system-arm -M highbank -net nic,model=allwinner-emac -device allwinner-a10

hw: Mark devices picking up char backends actively FIXME
Character devices defined with -serial and -parallel are for board
initialization to wire up. Board code examines serial_hds[] and
parallel_hds[] to find them, and creates devices with their qdev
chardev properties set accordingly.
Except a few devices go on a fishing expedition for a suitable backend
instead of exposing a chardev property for board code to set: they use
serial_hds[] (often via qemu_char_get_next_serial()) or parallel_hds[]
in their realize() or init() method to connect to a backend.
Picking up backends that way works when the devices are created by
board code. But it's inappropriate for -device or device_add. Not
only is it inconsistent with how the other characrer device models
work (they connect to a backend explicitly identified by a "chardev"
property), it breaks when the backend has been picked up by the board
or a previous -device / device_add already.
Example:
$ qemu-system-ppc64 -M bamboo -S -device i82378 -device pc87312 -device pc87312
qemu-system-ppc64: -device pc87312: Property 'isa-parallel.chardev' can't take value 'parallel0', it's in use

Drives defined with if!=none are for board initialization to wire up.
Board code calls drive_get() or similar to find them, and creates

CVE-2015-1779: limit size of HTTP headers from websockets clients
The VNC server websockets decoder will read and buffer data from
websockets clients until it sees the end of the HTTP headers,
as indicated by \r\n\r\n. In theory this allows a malicious to
trick QEMU into consuming an arbitrary amount of RAM. In practice,
because QEMU runs g_strstr_len() across the buffered header data,
it will spend increasingly long burning CPU time searching for
the substring match and less & less time reading data. So while
this does cause arbitrary memory growth, the bigger problem is
that QEMU will be burning 100% of available CPU time.
A novnc websockets client typically sends headers of around
512 bytes in length. As such it is reasonable to place a 4096
byte limit on the amount of data buffered while searching for
the end of HTTP headers.

CVE-2015-1779: incrementally decode websocket frames
The logic for decoding websocket frames wants to fully
decode the frame header and payload, before allowing the
VNC server to see any of the payload data. There is no
size limit on websocket payloads, so this allows a
malicious network client to consume 2^64 bytes in memory
in QEMU. It can trigger this denial of service before
the VNC server even performs any authentication.
The fix is to decode the header, and then incrementally
decode the payload data as it is needed. With this fix
the websocket decoder will allow at most 4k of data to
be buffered before decoding and processing payload.

rcu: do not create thread in pthread_atfork callback
If QEMU forks after the CPU threads have been created, qemu_mutex_lock_iothread
will not be able to do qemu_cpu_kick_thread. There is no solution other than
assuming that forks after the CPU threads have been created will end up in an
exec. Forks before the CPU threads have been created (such as -daemonize)
have to call rcu_after_fork manually.
Notably, the oxygen theme for GTK+ forks and shows a "No such process" error
without this patch.
This patch can be reverted once the iothread loses the "kick the TCG thread"
magic.
User-mode emulation does not use the iothread, so it can also call
rcu_after_fork.

qom: Fix object_property_add_alias() with [*]
Commit 8074264 (qom: Add description field in ObjectProperty struct)
introduced property descriptions and copied them for alias properties.
Instead of using the caller-supplied property name, use the returned
property name for setting the description. This avoids an Error when
setting a property description for a property with literal "[*]" that
doesn't exist due to automatic property naming in object_property_add().

AHCI: Protect cmd register
Many bits in the CMD register are supposed to be strictly read-only.
We should not be deleting them on every write.
As a side-effect: pay explicit attention to when a guest marks off
the FIS Receive or Start bits, and disable the status bits ourselves,
instead of letting them implicitly fall off.

Currently, we attempt to re-map the buffers every time they
are adjusted, but while the AHCI engines are off, these registers
may contain stale values, so we should not attempt to re-map these
values until the engines are reactivated.

block: Fix unaligned zero write
If the zero write is not aligned, bdrv_co_do_pwritev will segfault
because of accessing to the NULL qiov passed in by bdrv_co_write_zeroes.
Fix this by allocating a local qiov in bdrv_co_do_pwritev if the request
is not aligned. (In this case the padding iovs are necessary anyway, so
it doesn't hurt.)
Also add a check at the end of bdrv_co_do_pwritev to clear the zero flag
if padding is involved.

migration: remove last_sent_block from save_page_header
Compression code (still not on tree) want to call this funtion from
outside the migration thread, so we can't write to last_sent_block.
Instead of reverting full patch:
[PULL 07/11] save_block_hdr: we can recalculate
Just revert the parts that touch last_sent_block.

rdma: Fix cleanup in error paths
As part of commit e325b49a320b493cc5d69e263751ff716dc458fe,
order in which resources are destroyed was changed for fixing
a seg fault. Due to this change, CQ will never get destroyed as
CQ should be destroyed after QP destruction. Seg fault is caused
improper cleanup when connection fails. Fixing cleanup after
connection failure and order in which resources are destroyed

Avoid crashing on multiple -incoming

an invalid state transition incoming->incoming). Instead we now
take the last -incoming option, e.g.:
qemu-system-x86_64 -nographic -incoming tcp::4444 -incoming defer

exec: avoid possible overwriting of mmaped area in qemu_ram_remap
It is not necessary to munmap an area before remapping it with MAP_FIXED;
if the memory region specified by addr and len overlaps pages of any
existing mapping, then the overlapped part of the existing mapping will
be discarded.
On the other hand, if QEMU does munmap the pages, there is a small
probability that another mmap sneaks in and catches the just-freed
portion of the address space. In effect, munmap followed by
mmap(MAP_FIXED) is a use-after-free error, and Coverity flags it
as such. Fix it.

target-ppc: Remove POWER5+ v0.0 that never existed
IBM uses low 16bits to specify the chip version of a POWER CPU.
So there has never been an actual silicon with PVR = 0x003B0000.
The first silicon would have PVR 0x003B0100 but it is very unlikely
to find it in any machine shipped to any customer as it was too raw.
This removes CPU_POWERPC_POWER5P_v00 definition and changes
POWER5+ and POWERgs aliases (which are synonyms) to point to
POWER5+_v2.1 which can still be found in real machines.

virtio-net: validate backend queue numbers against bus limitation
We don't validate the backend queue numbers against bus limitation,
this will easily crash qemu if it exceeds the limitation which will
hit the abort() in virtio_del_queue(). An example is trying to
starting a virtio-net device with 256 queues. E.g:
./qemu-system-x86_64 -netdev tap,id=hn0,queues=256 -device
virtio-net-pci,netdev=hn0
Fixing this by doing the validation and fail early.

commit 9b70c1790acacae54d559d38ca69186a85040bb8
virtio-serial: switch to standard-headers
changes virtio_console_config size from 8 to 12 bytes:
it adds an optional 4 byte emerg_wr field.
As this crosses a power of two boundary, this changes the PCI BAR size,
which breaks migration compatibility with old qemu machine types.
It's probably a problem for other transports as well.
As a temporary fix, as we don't yet support this new field anyway,
simply make the config size smaller at init time.
Long terms we probably want something along the lines
of virtio_net_set_config_size.

cpus: Don't kick un-realized cpus.
following a464982499b2f637f6699e3d03e0a9d2e0b5288b, it's now possible for
there to be attempts to take the BQL before CPUs have been realized in
cases where a machine model inits peripherals before the first CPU.
BQL lock aquisition kicks the first_cpu, leading to a segfault if this
happens pre-realize. Guard the CPU kick routine to perform no action for
a CPU that doesn't exist or doesn't have a thread yet.
There was a fix to this with commit
6b49809c597331803ea941eadda813e5bb4e8fe2, but the check there misses
the case where the CPU has been inited and not realized. Strengthen the
check to make sure that the first_cpu has a thread (i.e. it is
realized) before allowing the kick.

i6300esb: Fix signed integer overflow
If the guest programs a sufficiently large timeout value an integer
overflow can occur in i6300esb_restart_timer(). e.g. if the maximum
possible timer preload value of 0xfffff is programmed then we end up with
the calculation:
timeout = get_ticks_per_sec() * (0xfffff << 15) / 33000000;
get_ticks_per_sec() returns 1000000000 (10^9) giving:
10^9 * (0xfffff * 2^15) == 0x1dcd632329b000000 (65 bits)
Obviously the division by 33MHz brings it back under 64-bits, but the
overflow has already occurred.
Since signed integer overflow has undefined behaviour in C, in theory this
could be arbitrarily bad. In practice, the overflowed value wraps around
to something negative, causing the watchdog to immediately expire, killing
the guest, which is still fairly bad.
The bug can be triggered by running a Linux guest, loading the i6300esb
driver with parameter "heartbeat=2046" and opening /dev/watchdog. The
watchdog will trigger as soon as the device is opened.
This patch corrects the problem by using muldiv64(), which effectively
allows a 128-bit intermediate value between the multiplication and
division.

i6300esb: Correct endiannness
The IO operations for the i6300esb watchdog timer are marked as
DEVICE_NATIVE_ENDIAN. This is not correct, and - as a PCI device - should
be DEVICE_LITTLE_ENDIAN.
This allows i6300esb to work on ppc targets (yes, using an Intel ICH
derived device on ppc is a bit odd, but the driver exists on the guest
and there's no more obviously suitable watchdog device).

arm/virt doesn't. It could be argued that that's an error in
"hw/arm/virt.c"; on the other hand, all of the other fw_cfg providing
boards set the interface version to 1 manually, despite the device
coming from the same, shared implementation. Therefore, instead of
adding
fw_cfg_add_i32(fw_cfg, FW_CFG_ID, 1);
to arm/virt, consolidate all such existing calls in the fw_cfg

the run---with some exceptions (rcu_stress_count for rcutorture,
n_nodes for test-rcu-list): fix them to use the same technique.
For test-rcu-list, remove the mostly unused member "val" from the
list. Then, use a mutex to protect the global counts.
Performance does not matter there because every thread will only enter
the critical section once.
Remaining uses of atomic instructions are for ints or pointers.

My pattern was cyclical every 256 bytes, so it missed a fairly obvious
failure case. Add some rand() pepper into the test pattern, and for large
patterns that exceed 256 sectors, start writing an ID per-sector so that
we never generate identical sector patterns.

ahci: Fix sglist offset manipulation for BE machines
This does not bother DMA, because DMA generally transfers
the entire SGList in one shot if it can.
PIO, on the other hand, tries to transfer just one sector
at a time, and will make multiple visits to the sglist
to fetch memory addresses.
Fix the memory address calculaton when we have an offset
by moving the offset addition OUTSIDE of the le64_to_cpu

linux-user/main.c: Remove redundant end_exclusive() in arm_kernel_cmpxchg64_helper()
start/end_exclusive() need be pairs, except the start_exclusive() in
stop_all_tasks() which is only used by force_sig(), which will be abort.
So at present, start_exclusive() in stop_all_task() need not be paired.
queue_signal() may call force_sig(), or return after kill pid (or queue
signal). If could return from queue_signal(), stop_all_task() would not
be called in time, the next end_exclusive() would be issue.
So in arm_kernel_cmpxchg64_helper() for ARM, need remove end_exclusive()
after queue_signal(). The related commit: "97cc756 linux-user: Implement

target-i386: Haswell-noTSX and Broadwell-noTSX
With the Intel microcode update that removed HLE and RTM, there will be
different kinds of Haswell and Broadwell CPUs out there: some that still
have the HLE and RTM features, and some that don't have the HLE and RTM
features. On both cases people may be willing to use the pc-*-2.3

So, to cover both cases, introduce Haswell-noTSX and Broadwell-noTSX CPU

numa: Print warning if no node is assigned to a CPU
We need all possible CPUs (including hotplug ones) to be present in the
SRAT when QEMU starts. QEMU already does that correctly today, the only
problem is that when a CPU is omitted from the NUMA configuration, it is
silently assigned to node 0.
Check if all CPUs up to max_cpus are present in the NUMA configuration
and warn about missing CPUs.
Make it just a warning, to allow management software to be updated if
necessary. In the future we may make it a fatal error instead.
Command-line examples:
* Correct, no warning:
$ qemu-system-x86_64 -smp 2,maxcpus=4
$ qemu-system-x86_64 -smp 2,maxcpus=4 -numa node,cpus=0-3
* Incomplete, with warnings:
$ qemu-system-x86_64 -smp 2,maxcpus=4 -numa node,cpus=0
qemu-system-x86_64: warning: CPU(s) not present in any NUMA nodes: 1 2 3

pc: fix default VCPU to NUMA node mapping
Since commit
dd0247e0 pc: acpi: mark all possible CPUs as enabled in SRAT
Linux kernel actually tries to use CPU to Node mapping from
QEMU provided SRAT table instead of discarding it, and that
in some cases breaks build_sched_domains() which expects
sane mapping where cores/threads belonging to the same socket
are on the same NUMA node.
With current default round-robin mapping of VCPUs to nodes
guest ends-up with cores/threads belonging to the same socket
being on different NUMA nodes.
For example with following CLI:
qemu-system-x86_64 -m 4G \
-cpu Opteron_G3,vendor=AuthenticAMD \
-smp 5,sockets=1,cores=4,threads=1,maxcpus=8 \
-numa node,nodeid=0 -numa node,nodeid=1
2.6.32 based kernels will hang on boot due to incorrectly built
sched_group-s list in update_sd_lb_stats()
Replacing default mapping with a manual, where VCPUs belonging to
the same socket are on the same NUMA node, fixes the issue for
guests which can't handle nonsense topology i.e. changing CLI to:
-numa node,nodeid=0,cpus=0-3 -numa node,nodeid=1,cpus=4-7
So instead of simply scattering VCPUs around nodes, provide
callback to map the same socket VCPUs to the same NUMA node,
which is what guests would expect from a sane hardware/BIOS.

numa: introduce machine callback for VCPU to node mapping
Current default round-robin way of distributing VCPUs among
NUMA nodes might be wrong in case on multi-core/threads
CPUs. Making guests confused wrt topology where cores from
the same socket are on different nodes.
Allow a machine to override default mapping by providing
MachineClass::cpu_index_to_socket_id()
callback which would allow it group VCPUs from a socket
on the same NUMA node.

virtio: serial: expose a 'guest_writable' callback for users
Users of virtio-serial may want to know when a port becomes writable. A
port can stop accepting writes if the guest port is open but not being
read from. In this case, data gets queued up in the virtqueue, and
after the vq is full, writes to the port do not succeed.
When the guest reads off a vq element, and adds a new one for the host
to put data in, we can tell users the port is available for more writes,
via the new ->guest_writable() callback.

hmp: Fix definition of command quit
The command handler is a union of two function types. If
cmd->user_print is set, handle_user_command() calls
cmd->mhandler.cmd_new(), else cmd->mhandler.cmd().
Command definitions must therefore either set both user_print() and
mhandler.cmd_new(), or only mhandler.cmd().
quit's sets user_print and mhandler.cmd(). handle_user_command()
calls hmp_quit() through mhandler.cmd_new() rather than
mhandler.cmd(), i.e. through a function pointer with a different type.
Broken in commit 7a7f325, v1.0.
Works in practice because hmp_quit() doesn't use its arguments, and
handle_user_command() ignores its function value.

exec: Respect as_tranlsate_internal length clamp
address_space_translate_internal will clamp the *plen length argument
based on the size of the memory region being queried. The iommu walker
logic in addresss_space_translate was ignoring this by discarding the
post fn call value of *plen. Fix by just always using *plen as the
length argument throughout the fn, removing the len local variable.
This fixes a bootloader bug when a single elf section spans multiple
QEMU memory regions.

profiler: Reenable built-in profiler
2ed1ebcf6 "timer: replace time() with QEMU_CLOCK_HOST" broke compile
when configured with --enable-profiler. Turned out the profiler has been
broken for a while.
This does s/qemu_time/tcg_time/ as the profiler only works in a TCG mode.
This also fixes the compile error.
This changes profile_getclock() to return nanoseconds rather than
CPU ticks as the "profile" HMP command prints seconds and there is no
platform-independent way to get ticks-per-second rate.
Since TCG is quite slow and get_clock() returns nanoseconds (fine
enough), this should not affect precision much.
This removes unused qemu_time_start and tlb_flush_time.

virtio-scsi: Fix assert in virtio_scsi_push_event
Hotplugging a scsi-disk may trigger the assertion in qemu_sgl_concat.

Assertion `skip == 0' failed.
This is introduced by commit 55783a55 (virtio-scsi: work around bug in
old BIOSes) which didn't check out_num when accessing out_sg[0].iov_len
(the same to in sg). For virtio_scsi_push_event, looking into out_sg
doesn't make sense because 0 req_size is intended.

The .d file name must match exactly what is used in the SUBDIR_DEVICES_MAK_DEP

just pass it in.
Similarly, the makefile target may not match the output file name, because
Makefile uses a temporary file. Instead of making assumptions on what the
Makefile does, emit the config-devices.mak file to stdout, and use the
passed-in destination as the makefile target

target-mips: fix hflags modified in delay / forbidden slot
All instructions which may change hflags terminate tb. However, this doesn't
work if such an instruction is placed in delay or forbidden slot.
gen_branch() clears MIPS_HFLAG_BMASK in ctx->hflags and then generates code
to overwrite hflags with ctx->hflags, consequently we loose any execution-time
hflags modifications. For example, in the following scenario hflag related to
Status.CU1 will not be updated:
/* Set Status.CU1 in delay slot */
mfc0 $24, $12, 0
lui $25, 0x2000
or $25, $25, $24
b check_Status_CU1
mtc0 $25, $12, 0
With this change we clear MIPS_HFLAG_BMASK in execution-time hflags if
instruction in delay or forbidden slot wants to terminate tb for some reason
(i.e. ctx->bstate != BS_NONE).
Also, die early and loudly if "unknown branch" is encountered as this should
never happen.

ui: enforce TLS when using websockets server
When TLS is required, the primary VNC server considers it to be
mandatory. ie the server admin decides whether or not TLS is used,
and the client has to comply with this decision. The websockets
server, however, treated it as optional, allowing non-TLS clients
to connect to a server which had setup TLS. Thus enabling websockets
lowers the security of the VNC server leaving the admin no way to
enforce use of TLS.
This removes the code that allows non-TLS fallback in the websockets
server, so that if TLS is requested for VNC it is now mandatory for
both the primary VNC server and the websockets VNC server.

Date: Tue Mar 17 13:42:57 2015 +0000
ui: fix setup of VNC websockets auth scheme with TLS
The way the websockets TLS code was integrated into the VNC server
made it essentially useless. The only time that the websockets TLS
support could be used is if the primary VNC server had its existing
TLS support disabled. ie QEMU had to be launched with:
# qemu -vnc localhost:1,websockets=5902,x509=/path/to/certs
Note the absence of the 'tls' flag. This is already a bug, because
the docs indicate that 'x509' is ignored unless 'tls' is given.
If the primary VNC server had TLS turned on via the 'tls' flag,
then this prevented the websockets TLS support from being used,
because it activates the VeNCrypt auth which would have resulted
in TLS being run over a TLS session. Of course no websockets VNC
client supported VeNCrypt so in practice, since the browser clients
cannot setup a nested TLS session over the main HTTPS connection,
so it would not even get past auth.
This patch causes us to decide our auth scheme separately for the
main VNC server vs the websockets VNC server. We take account of
the fact that if TLS is enabled, then the websockets client will
use https, so setting up VeNCrypt is thus redundant as it would
lead to nested TLS sessions.

ui: report error if user requests VNC option that is unsupported
If the VNC server is built without tls, sasl or websocket support
and the user requests one of these features, they are just silently
ignored. This is bad because it means the VNC server ends up running
in a configuration that is less secure than the user asked for.
It also leads to an tangled mass of preprocessor conditionals when
configuring the VNC server.
This ensures that the tls, sasl & websocket options are always
processed and an error is reported back to the user if any of
them were disabled at build time.

migration: Expose 'cancelling' status to user
'cancelling' status was introduced by commit 51cf4c1a, mainly to avoid a
possible start of a new migration process while the previous one still exists.
But we didn't expose this status to user, instead we returned the 'active' state.
Here, we expose it to the user (such as libvirt), 'cancelling' status only
occurs for a short window before the migration aborts, so for users,
if they cancel a migration process, it will observe 'cancelling' status
occasionally.
Testing revealed that with older libvirt (anything 1.2.13 or less) will
print an odd error message if the state is seen, but that the migration
is still properly cancelled. Newer libvirt will be patched to recognize
the new state without the odd error message.

difference, as property setters shouldn't depend on icc_bridge.

usb/dev-storage: Fix QMP device_add missing encryption key failure
When the image is encrypted, QMP device_add creates the device, defers
actually attaching it to when the key becomes available, then returns
an error. This is wrong. device_add must either create the device
and succeed, or do nothing and fail.
The bug is in usb_msd_realize_storage(). It posts an error with
qerror_report_err(), and returns success. Device realization relies
on the return value, and completes. The QMP monitor, however, relies
on the posted error, and sends it in an error reply.
Reproducer:
$ qemu-system-x86_64 -nodefaults -display none -usb -qmp stdio -drive if=none,id=foo,file=geheim.qcow2
{"QMP": {"version": {"qemu": {"micro": 50, "minor": 2, "major": 2}, "package": ""}, "capabilities": []}}
{ "execute": "qmp_capabilities" }
{"return": {}}
{ "execute": "device_add", "arguments": { "driver": "usb-storage", "id": "bar", "drive": "foo" } }
{"error": {"class": "DeviceEncrypted", "desc": "'foo' (geheim.qcow2) is encrypted"}}
Even though we got an error back, the device got created just fine.
To demonstrate, let's unplug it again:
{"execute":"device_del","arguments": { "id": "bar" } }
{"timestamp": {"seconds": 1426003440, "microseconds": 237181}, "event": "DEVICE_DELETED", "data": {"path": "/machine/peripheral/bar/bar.0/legacy[0]"}}
{"timestamp": {"seconds": 1426003440, "microseconds": 238231}, "event": "DEVICE_DELETED", "data": {"device": "bar", "path": "/machine/peripheral/bar"}}
{"return": {}}
Fix by making usb_msd_realize_storage() fail properly.

monitor usb: Inline monitor_read_bdrv_key_start()'s first part
monitor_read_bdrv_key_start() does several things:
1. If no key is needed, call completion_cb() and succeed
2. If we're in QMP context, call qerror_report_err() and fail
3. Start reading the key in the monitor.
This is two things too many. Inline 1. and 2. into its callers
monitor_read_block_device_key() and usb_msd_realize_storage().
Since monitor_read_block_device_key() only ever runs in HMP context,
drop 2. there.

block/vpc: remove disabled code from get_sector_offset
The code to check the bitmap for the allocation status of each sector
has been "disabled by reason" ever since the vpc driver existed.
The reason might be that we might end up reading sector by sector
in vpc_read if we really used it. This would be a performance desaster.
The current code would furthermore not work if the disabled parts get
reactivated since vpc_read and vpc_write only use get_sector_offset to
check the allocation status of the first sector of a read/write operation.
This might lead to sectors incorrectly treated as zero in vpc_read and
to sectors getting allocated twice in vpc_write.

block/vpc: make calculate_geometry spec conform
The VHD spec [1] allows for total_sectors of 65535 x 16 x 255 (~127GB)
represented by a CHS geometry. If total_sectors is greater
than 65535 x 16 x 255 this geometry is set as a maximum.
Qemu, Hyper-V and disk2vhd use this special geometry as an indicator
to use the image current size from the footer as disk size.
This patch changes vpc_create to effectively calculate a CxHxS geometry
for the given image size if possible while rounding up if necessary.
If the image size is too big to be represented in CHS we set the maximum
and write the exact requested image size into the footer.
This partly reverts commit 258d2edb, but leaves support for >127G disks
intact.

vpc: Ignore geometry for large images
The CHS calculation as done per the VHD spec imposes a maximum image
size of ~127 GB. Real VHD images exist that are larger than that.
Apparently there are two separate non-standard ways to achieve this:
You could use more heads than the spec does - this is the option that
qemu-img create chooses.
However, other images exist where the geometry is set to the maximum
(65535/16/255), but the actual image size is larger. Until now, such
images are truncated at 127 GB when opening them with qemu.
This patch changes the vpc driver to ignore geometry in this case and
only trust the size field in the header.

qcow2: Respect new_block in alloc_refcount_block()
When choosing a new place for the refcount table, alloc_refcount_block()
tries to infer the number of clusters used so far from its argument
cluster_index (which comes from the idea that if any cluster with an
index greater than cluster_index was in use, the refcount table would
have to be big enough already to describe cluster_index).
However, there is a cluster that may be at or after cluster_index, and
which is not covered by the refcount structures, and that is the new
refcount block new_block. Therefore, it should be taken into account for
the blocks_used calculation.
Also, because new_block already describes (or is intended to describe)
cluster_index, we may not put the new refcount structures there.

block: Deprecate QCOW/QCOW2 encryption
We've steered users away from QCOW/QCOW2 encryption for a while,
because it's a flawed design (commit 136cd19 Describe flaws in
qcow/qcow2 encryption in the docs).
In addition to flawed crypto, we have comically bad usability, and
plain old bugs. Let me show you.
= Example images =
I'm going to use a raw image as backing file, and two QCOW2 images,
one encrypted, and one not:
$ qemu-img create -f raw backing.img 4m
Formatting 'backing.img', fmt=raw size=4194304
$ qemu-img create -f qcow2 -o encryption,backing_file=backing.img,backing_fmt=raw geheim.qcow2 4m
Formatting 'geheim.qcow2', fmt=qcow2 size=4194304 backing_file='backing.img' backing_fmt='raw' encryption=on cluster_size=65536 lazy_refcounts=off
$ qemu-img create -f qcow2 -o backing_file=backing.img,backing_fmt=raw normal.qcow2 4m
Formatting 'normal.qcow2', fmt=qcow2 size=4194304 backing_file='backing.img' backing_fmt='raw' encryption=off cluster_size=65536 lazy_refcounts=off
= Usability issues =
== Confusing startup ==
When no image is encrypted, and you don't give -S, QEMU starts the
guest immediately:
$ qemu-system-x86_64 -nodefaults -display none -monitor stdio normal.qcow2
QEMU 2.2.50 monitor - type 'help' for more information
(qemu) info status
VM status: running
But as soon as there's an encrypted image in play, the guest is *not*
started, with no notification whatsoever:
$ qemu-system-x86_64 -nodefaults -display none -monitor stdio geheim.qcow2
QEMU 2.2.50 monitor - type 'help' for more information
(qemu) info status
VM status: paused (prelaunch)
If the user figured out that he needs to type "cont" to enter his
keys, the confusion enters the next level: "cont" asks for at most
*one* key. If more are needed, it then silently does nothing. The
user has to type "cont" once per encrypted image:
$ qemu-system-x86_64 -nodefaults -display none -monitor stdio -drive if=none,file=geheim.qcow2 -drive if=none,file=geheim.qcow2
QEMU 2.2.50 monitor - type 'help' for more information
(qemu) info status
VM status: paused (prelaunch)
(qemu) c
none0 (geheim.qcow2) is encrypted.
Password: ******
(qemu) info status
VM status: paused (prelaunch)
(qemu) c
none1 (geheim.qcow2) is encrypted.
Password: ******
(qemu) info status
VM status: running
== Incorrect passwords not caught ==
All existing encryption schemes give you the GIGO treatment: garbage
password in, garbage data out. Guests usually refuse to mount
garbage, but other usage is prone to data loss.
== Need to stop the guest to add an encrypted image ==
$ qemu-system-x86_64 -nodefaults -display none -monitor stdio
QEMU 2.2.50 monitor - type 'help' for more information
(qemu) info status
VM status: running
(qemu) drive_add "" if=none,file=geheim.qcow2
Guest must be stopped for opening of encrypted image
(qemu) stop
(qemu) drive_add "" if=none,file=geheim.qcow2
OK
Commit c3adb58 added this restriction. Before, we could expose images
lacking an encryption key to guests, with potentially catastrophic
results. See also "Use without key is not always caught".
= Bugs =
== Use without key is not always caught ==
Encrypted images can be in an intermediate state "opened, but no key".
The weird startup behavior and the need to stop the guest are there to
ensure the guest isn't exposed to that state. But other things still
are!
* drive_backup
$ qemu-system-x86_64 -nodefaults -display none -monitor stdio geheim.qcow2
QEMU 2.2.50 monitor - type 'help' for more information
(qemu) drive_backup -f ide0-hd0 out.img raw
Formatting 'out.img', fmt=raw size=4194304
I guess this writes encrypted data to raw image out.img. Good luck
with figuring out how to decrypt that again.
* commit
$ qemu-system-x86_64 -nodefaults -display none -monitor stdio geheim.qcow2
QEMU 2.2.50 monitor - type 'help' for more information
(qemu) commit ide0-hd0
I guess this writes encrypted data into the unencrypted raw backing
image, effectively destroying it.
== QMP device_add of usb-storage fails when it shouldn't ==
When the image is encrypted, device_add creates the device, defers
actually attaching it to when the key becomes available, then fails.
This is wrong. device_add must either create the device and succeed,
or do nothing and fail.
$ qemu-system-x86_64 -nodefaults -display none -usb -qmp stdio -drive if=none,id=foo,file=geheim.qcow2
{"QMP": {"version": {"qemu": {"micro": 50, "minor": 2, "major": 2}, "package": ""}, "capabilities": []}}
{ "execute": "qmp_capabilities" }
{"return": {}}
{ "execute": "device_add", "arguments": { "driver": "usb-storage", "id": "bar", "drive": "foo" } }
{"error": {"class": "DeviceEncrypted", "desc": "'foo' (geheim.qcow2) is encrypted"}}
{"execute":"device_del","arguments": { "id": "bar" } }
{"timestamp": {"seconds": 1426003440, "microseconds": 237181}, "event": "DEVICE_DELETED", "data": {"path": "/machine/peripheral/bar/bar.0/legacy[0]"}}
{"timestamp": {"seconds": 1426003440, "microseconds": 238231}, "event": "DEVICE_DELETED", "data": {"device": "bar", "path": "/machine/peripheral/bar"}}
{"return": {}}
This stuff is worse than useless, it's a trap for users.
If people become sufficiently interested in encrypted images to
contribute a cryptographically sane implementation for QCOW2 (or
whatever other format), then rewriting the necessary support around it
from scratch will likely be easier and yield better results than
fixing up the existing mess.
Let's deprecate the mess now, drop it after a grace period, and move
on.

pc: Disable vmdesc submission for old machines
Older PC machine types might by accident be backwards live migration compatible,
but with the new vmdesc self-describing blob in our live migration stream we
would break that compatibility.
Also users wouldn't expect massive behaviorial differences when updating to a
new version of QEMU while retaining their old machine type, especially not
potential breakage in tooling around live migration.
So disable vmdesc submission for old PC machine types.

to stumble over this.
This patch gives the user the chance to disable said self-describing part of

-machine suppress-vmdesc=on

migration: Read JSON VM description on incoming migration
One of the really nice things about the VM description format is that it goes
over the wire when live migration is happening. Unfortunately QEMU today closes
any socket once it sees VM_EOF coming, so we never give the VMDESC the chance to
actually land on the wire.
This patch makes QEMU read the description as well. This way we ensure that
anything wire tapping us in between will get the chance to also interpret the
stream.
Along the way we also fix virt tests that assume that number_bytes_sent on the
sender side is equal to number_bytes_read which was true before the VMDESC
patches and is true again with this patch.

linux-user: Access correct register for get/set_tls syscalls on ARM TZ CPUs
When support was added for TrustZone to ARM CPU emulation, we failed
to correctly update the support for the linux-user implementation of
the get/set_tls syscalls. This meant that accesses to the TPIDRURO
register via the syscalls were always using the non-secure copy of
the register even if native MRC/MCR accesses were using the secure
register. This inconsistency caused most binaries to segfault on startup
if the CPU type was explicitly set to one of the TZ-enabled ones like
cortex-a15. (The default "any" CPU doesn't have TZ enabled and so is
not affected.)
Use access_secure_reg() to determine whether we should be using
the secure or the nonsecure copy of TPIDRURO when emulating these
syscalls.

target-arm: Ignore low bit of PC in M-profile exception return
For the ARM M-profile cores, exception return pops various registers
including the PC from the stack. The architecture defines that if the
lowest bit in the new PC value is set (ie the PC is not halfword
aligned) then behaviour is UNPREDICTABLE. In practice hardware
implementations seem to simply ignore the low bit, and some buggy
RTOSes incorrectly rely on this. QEMU's behaviour was architecturally
permitted, but bringing QEMU into line with the hardware behaviour
allows more guest code to run. We log the situation as a guest error.
This was reported as LP:1428657.

target-arm: Fix handling of STM (user) with r15 in register list
The A32 encoding of LDM distinguishes LDM (user) from LDM (exception
return) based on whether r15 is in the register list. However for
STM (user) there is no equivalent distinction. We were incorrectly
treating "r15 in list" as indicating exception return for both LDM
and STM, with the result that an STM (user) involving r15 went into
an infinite loop. Fix this; note that the value stored for r15
in this case is the current PC regardless of our current mode.

target-arm: get_phys_addr_lpae: more xn control
This patch makes the following changes to the determination of
whether an address is executable, when translating addresses
using LPAE.
1. No longer assumes that PL0 can't execute when it can't read.
It can in AArch64, a difference from AArch32.
2. Use va_size == 64 to determine we're in AArch64, rather than
arm_feature(env, ARM_FEATURE_V8), which is insufficient.
3. Add additional XN determinants
- NS && is_secure && (SCR & SCR_SIF)
- WXN && (prot & PAGE_WRITE)
- AArch64: (prot_PL0 & PAGE_WRITE)
- AArch32: UWXN && (prot_PL0 & PAGE_WRITE)
- XN determination should also work in secure mode (untested)
- XN may even work in EL2 (currently impossible to test)
4. Cleans up the bloated PAGE_EXEC condition - by removing it.
The helper get_S1prot is introduced. It may even work in EL2,
when support for that comes, but, as the function name implies,
it only works for stage 1 translations.

target-arm: fix get_phys_addr_v6/SCTLR_AFE access check
Introduce simple_ap_to_rw_prot(), which has the same behavior as
ap_to_rw_prot(), but takes the 2-bit simple AP[2:1] instead of
the 3-bit AP[2:0]. Use this in get_phys_addr_v6 when SCTLR_AFE
is set, as that bit indicates we should be using the simple AP
format.
It's unlikely this path is getting used. I don't see CR_AFE
getting used by Linux, so possibly not. If it had been, then
the check would have been wrong for all but AP[2:1] = 0b11.
Anyway, this should fix it up, in case it ever does get used.

Synchronizes the guest TOD clock across a migration by sending the guest TOD
clock value to the destination system. If the guest TOD clock is not preserved
across a migration then the guest's view of time will snap backwards if the
destination host clock is behind the source host clock. This will cause the
guest to hang immediately upon resuming on the destination system.

s390x: Replace unchecked qdev_init() by qdev_init_nofail()
s390_flic_init() is a helper to create and realize either
"s390-flic-kvm" or "s390-flic-qemu". When qdev_init() fails, it
complains to stderr and succeeds.
Except it can't actually fail, because the "s390-flic-qemu" is a dummy
without a realize method, and "s390-flic-kvm"'s realize can't fail,
even when the kernel device is really unavailable. Odd.
Replace qdev_init() by qdev_init_nofail() to make "can't fail" locally
obvious, and get rid of the unreachable error reporting.

tcg: Change translator-side labels to a pointer
This is improved type checking for the translators -- it's no longer
possible to accidentally swap arguments to the branch functions.
Note that the code generating backends still manipulate labels as int.
With notable exceptions, the scope of the change is just a few lines
for each target, so it's not worth building extra machinery to do this
change in per-target increments.

net: synchronize net_host_device_remove with host_net_remove_completion
Using net_host_check_device is unnecessary. qemu_del_net_client asserts
for the non-peer case that it can only process NIC type NetClientStates,
and that assertion is valid for the peered case as well, so move it and
use the same check in net_host_device_remove. host_net_remove_completion
is already checking the type.

queue: fix QSLIST_INSERT_HEAD_ATOMIC race
There is a not-so-subtle race in QSLIST_INSERT_HEAD_ATOMIC.
Because atomic_cmpxchg returns the old value instead of a success flag,
QSLIST_INSERT_HEAD_ATOMIC was checking for success by comparing against
the second argument to atomic_cmpxchg. Unfortunately, this only works
if the second argument is a local or thread-local variable.
If it is in memory, it can be subject to common subexpression elimination
(and then everything's fine) or reloaded after the atomic_cmpxchg,
depending on the compiler's whims. If the latter happens, the race can
happen. A thread can sneak in, doing something on elm->field.sle_next
after the atomic_cmpxchg and before the comparison. This causes a wrong
failure, and then two threads are using "elm" at the same time. In the
case discovered by Christian, the sequence was likely something like this:
thread 1 | thread 2
QSLIST_INSERT_HEAD_ATOMIC |
atomic_cmpxchg succeeds |
elm added to list |
| steal release_pool
| QSLIST_REMOVE_HEAD
| elm removed from list
| ...
| QSLIST_INSERT_HEAD_ATOMIC
| (overwrites sle_next)
spurious failure |
atomic_cmpxchg succeeds |
elm added to list again |
|
steal release_pool |
QSLIST_REMOVE_HEAD |
elm removed again |
The last three steps could be done by a third thread as well.
A reproducer that failed in a matter of seconds is as follows:
- the guest has 32 VCPUs on a 28 core host (hyperthreading was enabled),
memory was 16G just to err on the safe side (the host has 64G, but hey
at least you need no s390)
- the guest has 24 null-aio virtio-blk devices using dataplane
(-object iothread,id=ioN -drive if=none,id=blkN,driver=null-aio,size=500G
-device virtio-blk-pci,iothread=ioN,drive=blkN)
- the guest also has a single network interface. It's only doing loopback
tests so slirp vs. tap and the model doesn't matter.
- the guest is running fio with the following script:

Do not use basename(3) because there are 2 versions of
this function which differs when argument ends with

uapi/virtio_scsi: allow overriding CDB/SENSE size
QEMU wants to use virtio scsi structures with
a different VIRTIO_SCSI_CDB_SIZE/VIRTIO_SCSI_SENSE_SIZE,
let's add ifdefs to allow overriding them.
Keep the old defines under new names:
VIRTIO_SCSI_CDB_DEFAULT_SIZE/VIRTIO_SCSI_SENSE_DEFAULT_SIZE,
since that's what these values really are:
defaults for cdb/sense size fields.

target-mips: add missing MSACSR and restore fp_status and hflags
Save MSACSR state. Also remove fp_status, msa_fp_status, hflags and restore
them in post_load() from the architectural registers.
Float exception flags are not present in vmstate. Information they carry
is used only by softfloat caller who translates them into MIPS FCSR.Cause,
FCSR.Flags and then they are cleared. Therefore there is no need for saving
them in vmstate.

conform to the documentation and to bring it into line with

hw/arm/virt: fix cmdline parsing bug with CPU options and smp > 1
The recently introduced feature that allows 32 bit guests to be
executed under KVM on a 64-bit host incorrectly handles the case
where more than 1 cpu is specified using '-smp N'
For instance, this invocation of qemu
qemu-system-aarch64 -M virt -cpu cortex-a57,aarch64=off -smp 2
produces the following error
qemu-system-aarch64: Expected key=value format, found aarch64
which is caused by the destructive parsing performed by
cpu_common_parse_features(), resulting in subsequent attempts
to parse the CPU option string (for each additional CPU) to fail.
So duplicate the string before parsing it, and free it directly
afterwards.

target-i386: Clean up misuse of qdev_init() in realize method
x86_cpu_apic_realize() calls qdev_init() to realize the APIC.
qdev_init()'s error handling has unwanted side effects: it unparents
the device, and it calls qerror_report_err().
qerror_report_err() is always inappropriate in realize methods,
because it doesn't return the Error object. It either reports the
error to stderr or the human monitor, or it stores it in the QMP
monitor, where it makes the QMP command fail even though the realize
method succeeded.
Fortunately, qdev_init() can't actually fail here, because realize
can't fail for any of the three possible APIC device models.
Clean up by cutting out the qdev_init() middle-man: set property
"realized" directly.

block/raw-posix: fix launching with failed disks
Since commit c25f53b06eba1575d5d0e92a0132455c97825b83 ("raw: Probe
required direct I/O alignment") QEMU has failed to launch if image files
produce I/O errors.
Previously, QEMU would launch successfully and the guest would see the
errors when attempting I/O.
This is a regression and may prevent multipath I/O inside the guest,
where QEMU must launch and let the guest figure out by itself which
disks are online.
Tweak the alignment probing code in raw-posix.c to explicitly look for
EINVAL on Linux instead of bailing. The kernel refuses misaligned
requests with this error code and other error codes can be ignored.

iotests: Drop vpc from 004's and 104's format list
Both tests require the test image to have a specific size; this cannot
be guaranteed by vpc (unless tuning the test specifically for that
format).
It is safe to exclude vpc from 004 because what is tested there is
implemented in a generic part in the block layer and not
format-specific.
It is safe to exclude vpc from 104 because for vpc basically every image
size is "unaligned", so if that would break at some point in time, we
would quickly notice just by running the generic tests.

ahci: Recompute cur_cmd on migrate post load
When the AHCI HBA device is migrated, all of the information that
led to the request being created is stored in the AHCIDevice
structures, except for pointers into guest data where return
information needs to be stored.
The "cur_cmd" field is usually responsible for this.
To rebuild the cur_cmd pointer post-migration, we can utilize
the busy_slot index to figure out where the command header
we are still processing is.
This allows a machine in a halted state from rerror=stop or
werror=stop to be migrated and resume operations without issue.

This is easy, since start_dma already restarts processing from the

Migration is also easy to cover; the comment about busy_slot is
wrong, busy_slot will only be set if there is an error. In this
case we have nothing to do really. The core IDE code will restart
the operation and command list processing will proceed after the
erroring command has been completed.

No version numbering changes because AHCI is not officially
migratable (and we can all see with good reason why) so we
do not impact any official builds by altering the stream and
leaving it at version 1.
This fixes the rerror=stop/werror=stop test case where we wish
to migrate a halted job. Previously, the error code would not
migrate, so even if the job completed successfully, AHCI would
report an error because it would still have the placeholder
error code from initialization time.

ide: migrate initial request state via IDEBus
This only breaks backwards migration compatibility if the bus is in
an error state. It is in principle possible to avoid this by making
two subsections (one for version 1, and one for version 2, but with
the same name) with different "_needed" callbacks. The v1 callback would
return true if error_status != 0 and the bus is PATA; the v2 callback
would return true if error_status != 0 and the bus is AHCI.
Forward migration keeps working.

BlockConf: Call backend functions to detect geometry and blocksizes
geometry: hd_geometry_guess function autodetects the drive geometry.
This patch adds a block backend call, that probes the backing device
geometry. If the inner driver method is implemented and succeeds
(currently only for DASDs), the blkconf_geometry will pass-through
the backing device geometry. Otherwise will fallback to old logic.
blocksize: This patch initializes blocksize properties to 0.
In order to set the property a blkconf_blocksizes was introduced.
If user didn't set physical or logical blocksize, it will
retrieve its value from a driver (only succeeds for DASD), otherwise
it will set default 512 value.
The blkconf_blocksizes call was added to all users of BlkConf.

blkdebug: fix "once" rule
Background:
The blkdebug scripts are currently engineered so that when a debug
event occurs, a prefilter browses a master list of parsed rules for a
certain event and adds them to an "active list" of rules to be used for
the forthcoming action, provided the events and state numbers match.
Then, once the request is received, the last active rule is used to
inject an error if certain parameters match.
This active list is cleared every time the prefilter injects a new
rule for the first time during a debug event.
The "once" rule currently causes the error injection, if it is
triggered, to only clear the active list. This is insufficient for
preventing future injections of the same rule.
Remedy:
This patch /deletes/ the rule from the list that the prefilter
browses, so it is gone for good. In V2, we remove only the rule of
interest from the active list instead of allowing the "once" rule to
clear the entire list of active rules.
Impact:
This affects iotests 026. Several ENOSPC tests that used "once" can
be seen to have output that shows multiple failure messages. After
this patch, the error messages tend to be smaller and less severe, but
the injection can still be seen to be working. I have patched the
expected output to expect the smaller error messages.

Furthermore, add another filter to _filter_img_create in common.filter
which filters out the refcount_bits value.
This is necessary for test 079, which does actually work with any
refcount width, but invoking qemu-img directly leads to the
refcount_bits value being visible in the output; use _make_test_img

qcow2: Helper function for refcount modification
Since refcounts do not always have to be a uint16_t, all refcount blocks
and arrays in memory should not have a specific type (thus they become
pointers to void) and for accessing them, two helper functions are used
(a getter and a setter). Those functions are called indirectly through
function pointers in the BDRVQcowState so they may later be exchanged
for different refcount orders.
With the check and repair functions using this function, the refcount
array they are creating will be in big endian byte order; additionally,
using realloc_refcount_array() makes the size of this refcount array
always cluster-aligned. Both combined allow rebuild_refcount_structure()
to drop the bounce buffer which was used to convert parts of the
refcount array to big endian byte order and store them on disk. Instead,
those parts can now be written directly.

qcow2: Helper for refcount array reallocation
Add a helper function for reallocating a refcount array, independent of

handles failed reallocations gracefully.
The helper function will always align the buffer size to a cluster
boundary; if storing the refcounts in such an array in big endian byte
order, this makes it possible to write parts of the array directly as
refcount blocks into the image file.

an absolute refcount that should be reached ("l2_refcount - 1" in
expand_zero_clusters_in_l1()). Therefore, the addend should be unsigned
as well; this will be especially important for 64 bit refcounts.
Because update_refcount() then no longer knows whether the refcount
should be increased or decreased, it now requires an additional flag
which specified exactly that. The same applies to
qcow2_update_cluster_refcount().

qcow2: Only return status from qcow2_get_refcount
Refcounts can theoretically be of type uint64_t; in order to be able to
represent the full range, qcow2_get_refcount() cannot use a single
variable to represent both all refcount values and also keep some values
reserved for errors.
One solution would be to add an Error pointer parameter to
qcow2_get_refcount(); however, no caller could (currently) pass that
error message, so it would have to be emitted immediately and be
passed to the next caller by returning -EIO or something similar.
Therefore, an Error parameter does not offer any advantages here.
The solution applied by this patch is simpler to use. Because no caller
would be able to pass the error message, they would have to print it and
free it, whereas with this patch the caller only needs to pass the
returned integer (which is often a no-op from the code perspective,
because that integer will be stored in a variable "ret" which will be
returned by the fail path of many callers).

qcow2: Do not return new value after refcount update
qcow2_update_cluster_refcount() does not have any quick access to the
new refcount value, it has to call qcow2_get_refcount(). Some callers do
not need that new value at all, others call qcow2_get_refcount()
themselves anyway (albeit in a different code path, which can however be
easily changed), therefore there is no advantage in making
qcow2_update_cluster_refcount() return the new value. Drop it.

qcow2: Add refcount_bits to format-specific info
Add the bit width of every refcount entry to the format-specific
information.
In contrast to lazy_refcounts and the corrupt flag, this should be
always emitted, even for compat=0.10 although it does not support any
refcount width other than 16 bits. This is because if a boolean is
optional, one normally assumes it to be false when omitted; but if an
integer is not specified, it is rather difficult to guess its value.
This new field breaks some test outputs, fix them.

x86: fix SS selector in SYSRET
According to my reading of the Intel documentation, the SYSRET instruction
is supposed to force the RPL bits of the %ss register to 3 when returning
to user mode. The actual sequence is:
SS.Selector <-- (IA32_STAR[63:48]+8) OR 3; (* RPL forced to 3 *)
However, the code in helper_sysret() leaves them at 0 (in other words, the "OR
3" part of the above sequence is missing). It does set the privilege level
bits of %cs correctly though.
This has caused me trouble with some of my VxWorks development: code that runs
okay on real hardware will crash on QEMU, unless I apply the patch below.

scsi: Improve error reporting for invalid drive property
When setting "realized" fails, scsi_bus_legacy_add_drive() passes the
error to qerror_report_err(), then returns an unspecific "Setting
drive property failed" error, which is reported further up the call
chain.
Example:
$ qemu-system-x86_64 -nodefaults -S -display none \
> -drive if=scsi,id=foo,file=tmp.qcow2 -global isa-fdc.driveA=foo
qemu-system-x86_64: -drive if=scsi,id=foo,file=tmp.qcow2: Property 'scsi-disk.drive' can't take value 'foo', it's in use
qemu-system-x86_64: Setting drive property failed
qemu-system-x86_64: Initialization of device lsi53c895a failed: Device initialization failed
Clean up the obvious way: simply return the original error to the
caller. Gets rid of the second message in the above error cascade.

hw: Propagate errors through qdev_prop_set_drive()
Three kinds of callers:
1. On failure, report the error and abort
Passing &error_abort does the job. No functional change.
2. On failure, report the error and exit()
This is qdev_prop_set_drive_nofail(). Error reporting moves from
qdev_prop_set_drive() to its caller. Because hiding away the error
in the monitor right before exit() isn't helpful, replace
qerror_report_err() by error_report_err(). Shouldn't make a
difference, because qdev_prop_set_drive_nofail() should never be
used in QMP context.
3. On failure, report the error and recover
This is usb_msd_init() and scsi_bus_legacy_add_drive(). Error
reporting and freeing the error object moves from
qdev_prop_set_drive() to its callers.
Because usb_msd_init() can't run in QMP context, replace
qerror_report_err() by error_report_err() there.
No functional change.
scsi_bus_legacy_add_drive() calling qerror_report_err() is of
course inappropriate, but this commit merely makes it more obvious.
The next one will clean it up.

scsi: Clean up duplicated error in legacy if=scsi code
Commit a818a4b changed scsi_bus_legacy_handle_cmdline() to report
errors from scsi_bus_legacy_add_drive() with error_report() in
addition to returning them. That's inappropriate.
Two kinds of callers:
1. realize methods (devices "esp", "virtio-scsi-device" and
"spapr-vscsi")
The error object gets passed up the call chain until it gets
reported again and freed.
Example:
$ qemu-system-arm -M virt -S -display none \
> -drive if=scsi,id=foo,bus=1,file=tmp.qcow2 \
> -device nec-usb-xhci -device usb-storage,drive=foo \
> -device virtio-scsi-pci
qemu-system-arm: -drive if=scsi,id=foo,bus=1,file=tmp.qcow2: Property 'scsi-disk.drive' can't take value 'foo', it's in use
qemu-system-arm: -drive if=scsi,id=foo,bus=1,file=tmp.qcow2: Setting drive property failed
qemu-system-arm: -device virtio-scsi-pci: Setting drive property failed
qemu-system-arm: -device virtio-scsi-pci: Device initialization failed
qemu-system-arm: -device virtio-scsi-pci: Device 'virtio-scsi-pci' could not be initialized
The second message in this error cascade comes from
scsi_bus_legacy_handle_cmdline(). The error object then gets
passed up to the qdev_init() called from
virtio_scsi_pci_init_pci(), which reports it again.
2. init methods (devices "am53c974", "dc390", "lsi53c895a",
"lsi53c810", "megasas", "megasas-gen2")
init methods need to report their errors with qerror_report().
These don't. The inappropriate error_report() papers over the bug.
error_report() isn't the same as qerror_report() in QMP context,
but this can't actually happen: QMP can still only hot-plug, and
callers call scsi_bus_legacy_handle_cmdline() only on cold-plug.
Except for sysbus_esp_realize(), but that can't be hot-plugged at
all, as far as I can tell.
Fix the init methods and drop the inappropriate error_report() in
scsi_bus_legacy_handle_cmdline().

rcu: handle forks safely
After forking, only the calling thread is duplicated in the child process.
The call_rcu thread has to be recreated in the child. Exploit the fact
that only one thread exists (same as when constructors run), and just redo
the entire initialization to ensure the threads are in the proper state.
The only additional things to do are emptying the list of threads
registered with RCU, and unlocking the lock that was taken in the prepare
callback (implementations are allowed to fail pthread_mutex_init()
if the mutex is still locked).

qemu-thread: do not use PTHREAD_MUTEX_ERRORCHECK
PTHREAD_MUTEX_ERRORCHECK is completely broken with respect to fork.
The way to safely do fork is to bring all threads to a quiescent
state by acquiring locks (either in callers---as we do for the
iothread mutex---or using pthread_atfork's prepare callbacks)
and then release them in the child.
The problem is that releasing error-checking locks in the child
fails under glibc with EPERM, because the mutex stores a different
owner tid than the duplicated thread in the child process. We
could make it work for locks acquired via pthread_atfork, by
recreating the mutex in the child instead of unlocking it
(we know that there are no other threads that could have taken
the mutex; but when the lock is acquired in fork's caller
that would not be possible.
The simplest solution is just to forgo error checking.

sun4u: switch m48t59 NVRAM to MMIO access
Real sun4u systems memory-map the NVRAM on the (ISA) ebus, so switch over to
MMIO from ioport access whilst setting the base year to 1968 as used by Sun
systems. This allows all SPARC64 OSs included in my tests to correctly detect
the NVRAM IC and read the hardware clock correctly upon boot.

s390-ccw.img: Allow bigger ramdisk sizes or offsets
The s390-ccw bios creates the the virtqueue at 100MB. For
big ramdisks or offsets (via zipl) this gets overwritten.
As a quick band-aid, lets move the virtqueue into the bss
section, which is at 0x7f00000. As the bios code (text) is
at 0x7e00000 we can now handle ramdisk which are ~27MB
bigger.
Long term we want to make the s390-ccw bios position
independent and load of at the end of memory.

s390x/kvm: implement handling of new SIGP orders
This patch adds handling code for the following SIGP orders:
- SIGP SET ARCHITECTURE
- SIGP SET PREFIX
- SIGP STOP
- SIGP STOP AND STORE STATUS
- SIGP STORE STATUS AT ADDRESS
SIGP STOP (AND STORE STATUS) are the only orders that can stay pending forever
(and may only be interrupted by resets), so special care has to be taken about
them. Their status also has to be tracked within QEMU. This patch takes
care of migrating this status (e.g. if migration happens during a SIGP STOP).
Due to the BQL, only one VCPU is currently able to execute SIGP handlers at a
time. According to the PoP, BUSY should be returned if another SIGP order is
currently being executed on a VCPU. This can only be implemented when the BQL
does not protect all handlers. For now, all SIGP orders on all VCPUs will be
serialized, which will be okay for the first shot.

s390x/kvm: more details for SIGP handler with one destination vcpu
Whenever a sigp order is to be executed by a target vcpu, we use run_on_cpu().
As we have only one pointer to pass all data to these sigp handlers, let's
introduce the struct sigp_info and use it as a transport container.
All orders targeting a single vcpu are now dispatched from a separate
handler. The destination vcpu is only valid for these orders and must not be
checked for SIGP SET ARCHITECTURE.
The sigp_info is filled with life in this new handler and used to pass the
information about the sigp order to the existing handlers. The cc is set
within these handlers.
Rename sigp_cpu_start() and sigp_cpu_restart() on the way to match the SIGP
order names (in order to avoid touching affected lines several times).

numero sign is the number sign key of Russian keyboard layout, we

this patch fixes it.
As number sign does not exsit in Russian keyboard layout[1][2], this
patch also removes the 'numbersign' from Russian keymap.

memsave: Improve and disambiguate error message
When requesting a size which cannot be read, the error message shows
a different address which is misleading to the user and it looks like
something's wrong with the address parsing. This is because the input
@addr variable is incremented in the memory dumping loop:
(qemu) memsave 0xffffffff8418069c 0xb00000 mem
Invalid addr 0xffffffff849ffe9c specified
Fix that by saving the original address and size and use them in the
error message:
(qemu) memsave 0xffffffff8418069c 0xb00000 mem
Invalid addr 0xffffffff8418069c/size 11534336 specified

target-i386: Require APIC ID to be explicitly set before CPU realize
On softmuu, instead of setting APIC ID automatically when creating a
X86CPU, require the property to be set before realizing the object
(which is already done by the CPU creation code on PC).
Keep apic_id = 0 by default on *-user so it can simply create a new CPU
object and realize it without extra steps (so target-i386 will be able
to use cpu_generic_init() eventually).

target-i386: Remove unused APIC ID default code
The existing apic_id = cpu_index code has no visible effect: the PC code
already initializes the APIC ID according to the topology on
pc_new_cpu(), and linux-user memcpy()s the CPU state (including
cpuid_apic_id) on cpu_copy().
Remove the dead code and simply let APIC ID to to be 0 by default. This

target-i386: Eliminate unnecessary get_cpuid_vendor() function
The function was used in only two places. In one of them, the function
made the code less readable by requiring temporary te[bcd]x variables.
In the other one we can simply inline the existing code.

The patch defines constants used by EEH RTAS calls and adds
callbacks sPAPRPHBClass::{eeh_set_option, eeh_get_state, eeh_reset,
eeh_configure}, which are going to be used as follows:
* RTAS calls are received in spapr_pci.c, sanity check is done
there.
* RTAS handlers handle what they can. If there is something it
cannot handle and the corresponding sPAPRPHBClass callback is
defined, it is called.
* Those callbacks are only implemented for VFIO now. They do ioctl()
to the IOMMU container fd to complete the calls. Error codes from
that ioctl() are transferred back to the guest.

target-ppc: Add versions to server CPU descriptions
5b79b1c "target-ppc: Create versionless CPU class per family if KVM" added
a dynamic CPU class registration with the name of the CPU family which
QEMU is running on. For example, this allowed specifying "-cpu POWER7"
on every version of POWER7 machine, not just the one which POWER7 was
an alias of. I.e. before 5b79b1c, "-cpu POWER7" would not work on real
POWER7 2.1 and would work on POWER7 2.3 only. The same story for POWER8.
However that patch broke POWER5+ support as POWER5+ CPU uses the same
name as the CPU class so dynamic registering of the POWER5+ class failed.
This redefines POWER5+ server CPUs by adding a version to them and adding
an alias for TCG case. KVM will use dynamically registered CPUs.
While we are here, do the same for 970 CPU.

PPC: Introduce the Virtual Time Base (VTB) SPR register
This patch adds basic support for the VTB.
PowerISA:
The Virtual Time Base (VTB) is a 64-bit incrementing counter.
Virtual Time Base increments at the same rate as the Time Base until its value
becomes 0xFFFF_FFFF_FFFF_FFFF (2 64 - 1); at the next increment its value
becomes 0x0000_0000_0000_0000. There is no interrupt or other indication when
this occurs.
The operation of the Virtual Time Base has the following additional
properties.
1. Loading a GPR from the Virtual Time Base has no effect on the accuracy of
the Virtual Time Base.
2. Copying the contents of a GPR to the Virtual Time Base replaces the
contents of the Virtual Time Base with the contents of the GPR.

vga: Expose framebuffer byteorder as a QOM property
The VGA device model now supports having the framebuffer in either endian,
and can be switched between these by the guest via a register in the qext
region.
However, in some cases (e.g. LE OS on the pseries machine) we have
existing guest that don't know about the endian switch register, but other
parts of the qemu code have better information to set a default endianness
than the VGA code does of itself.
In order to allow them to set a correct default endianness in these cases,
without breaking abstraction walls, this patch exposes the VGA framebuffer
endianness via a writable QOM property.

pseries: Move rtc_offset into RTC device's state structure
The initial creation of the PAPR RTC qdev class left a wart - the rtc's
offset was left in the sPAPREnvironment structure, accessed via a global.
This patch moves it into the RTC device's own state structure, were it
belongs. This requires a small change to the migration stream format. In
order to handle incoming streams from older versions, we also need to
retain the rtc_offset field in the sPAPREnvironment structure, so that it
can be loaded into via the vmsd, then pushed into the RTC device.
Since we're changing the migration format, this also takes the opportunity
to:
* Change the rtc offset from a value in seconds to a value in
nanoseconds, allowing nanosecond offsets between host and guest
rtc time, if desired.
* Remove both the already unused "next_irq" field and now unused
"rtc_offset" field from the new version of the spapr migration
stream

pseries: Make the PAPR RTC a qdev device
At present the PAPR RTC isn't a "device" as such - it's accessed only via
firmware/hypervisor calls, and is handled in the sPAPR core code. This
becomes inconvenient as we extend it in various ways.
This patch makes the PAPR RTC a separate device in the qemu device model.
For now, the only piece of device state - the rtc_offset - is still kept in
the global sPAPREnvironment structure. That's clearly wrong, but leaving
it to be fixed in a following patch makes for a clearer separation between
the internal re-organization of the device, and the behavioural changes
(because the migration stream format needs to change slightly when the
offset is moved into the device's own state).

pseries: Make RTAS time of day functions respect -rtc options
In the 'pseries' machine the real time clock is provided by a
paravirtualized firmware interface rather than a device per se; the RTAS
get-time-of-day and set-time-of-day calls.
Out current implementations of those work directly off host time (with
an offset), not respecting options such as clock=vm which can be
specified in the -rtc command line option.
This patch reworks the RTAS RTC code to respect those options, primarily
by basing them on the qemu_clock_get_ns(rtc_clock) function instead of
directly on qemu_get_timedate() (which essentially handles host time, not
virtual rtc time).
As a bonus, this means our get-time-of-day function now also returns
nanoseconds.

pseries: Add spapr_rtc_read() helper function
The virtual RTC time is used in two places in the pseries machine. First
is in the RTAS get-time-of-day function which returns the RTC time to the
guest. Second is in the spapr events code which is used to timestamp
event messages from the hypervisor to the guest.
Currently both call qemu_get_timedate() directly, but we want to change
that so we can properly handle the various -rtc options. In preparation,
create a helper function to return the virtual RTC time.

pseries: Add more parameter validation in RTAS time of day functions
Currently, the RTAS time of day functions only partially validate the
number of parameters they receive and return. Because of how the
parameters are used, this is unlikely to lead to a crash, but it's messy.
This patch adds the missing checks.

pseries: Move sPAPR RTC code into its own file
At the moment the RTAS (firmware/hypervisor) time of day functions are
implemented in spapr_rtas.c along with a bunch of other things. Since
we're going to be expanding these a bit, move the RTAS RTC related code
out into new file spapr_rtc.c. Also add its own initialization function,
spapr_rtc_init() called from the main machine init routine.

Currently, vmstate.h includes helper macro variants for 8, 16 and 32-bit

There aren't similar helpers for 64-bit unsigned integers, or any size of

Generalize QOM publishing of date and time from mc146818rtc.c
The mc146818rtc driver exposes the current RTC date and time via the "date"
property in QOM (which is also aliased to the machine's "rtc-time"
property). Currently it uses a custom visitor function rtc_get_date to
do this.
This patch introduces new helpers to the QOM core to expose struct tm
valued properties via a getter function, so that this functionality can be
more easily duplicated in other RTC implementations.

spapr-pci: Enable huge BARs
At the moment sPAPR only supports 512MB window for MMIO BARs. However
modern devices might want bigger 64bit BARs.
This extends MMIO window from 512MB to 62GB (aligned to
SPAPR_PCI_WINDOW_SPACING) and advertises it in 2 records in
the PHB "ranges" property. 32bit gets the space from
SPAPR_PCI_MEM_WIN_BUS_OFFSET till the end of 4GB, 64bit gets the rest
of the space. If no space is left, 64bit range is not advertised.
The MMIO space size is set to old value of 0x20000000 by default
for pseries machines older than 2.3.
The approach changes the device tree which is a guest visible change, however
it won't break migration as:
1. we do not support migration to older QEMU versions
2. migration to newer QEMU will migrate the device tree as well and since
the new layout only extends the old one and does not change address mappigns,
no breakage is expected here too.
SLOF change is required to utilize this extension.

pseries: Limit PCI host bridge "index" value
pseries guests can have large numbers of PCI host bridges. To avoid the
user having to specify a number of different configuration values for every
one, the device supports an "index" property which is a shorthand setting
the various window and configuration addresses from a predefined sensible
set.
There are some problems with the details at present:
* The "index" propery is signed, but negative values will create PCI
windows below where we expect, potentially colliding with other devices
* No limit is imposed on the "index" property and large values can
translate to extremely large window addresses. With PCI passthrough in
particular this can mean we exceed various mapping and physical address
limits causing the guest host bridge to not work in strange ways.
This patch addresses this, by making "index" unsigned, and imposing a
limit. Currently the limit allows indices from 0..255 which is probably
enough host bridges for the time being. It's fairly easy to extend if
we discover we need more.

target-ppc: Use right page size with hash table lookup
We look at two sizes specified in ISA (4K, 64K). If not found matching,
we consider it 16MB.
Without this patch we would fail to lookup address above 16MB range.
Below 16MB happened to work before because the kernel have a liner
mapping and we always looked up hash for 0xc000000000000000. The
actual real address was computed by using the 16MB offset
with the real address found with the above hash.

spapr_vio/spapr_iommu: Move VIO bypass where it belongs
Instead of tweaking a TCE table device by adding there a bypass flag,
let's add an alias to RAM and IOMMU memory region, and enable/disable
those according to the selected bypass mode.
This way IOMMU memory region can have size of the actual window rather
than ram_size which is essential for upcoming DDW support.
This moves bypass logic to VIO layer and keeps @bypass flag in TCE table
for migration compatibility only. This replaces spapr_tce_set_bypass()
calls with explicit assignment to avoid confusion as the function could
do something more that just syncing the @bypass flag.
This adds a pointer to VIO device into the sPAPRTCETable struct to provide
the sPAPRTCETable device a way to update bypass mode for the VIO device.

sheepdog: selectable object size support
Previously, qemu block driver of sheepdog used hard-coded VDI object size.
This patch enables users to handle VDI object size.
When you start qemu, you don't need to specify additional command option.
But when you create the VDI which doesn't have default object size
with qemu-img command, you specify object_size option.
If you want to create a VDI of 8MB object size,
you need to specify following command option.
# qemu-img create -o object_size=8M sheepdog:test1 100M
In addition, when you don't specify qemu-img command option,
a default value of sheepdog cluster is used for creating VDI.
# qemu-img create sheepdog:test2 100M

Also, using COROUTINE_YIELD is now even more confusing because this code

Instead of using the same function for entering and exiting coroutines,

This fixes a use-after-free scenario where reentering a coroutine that

meanwhile terminated) in the part of coroutine_swap() that follows
qemu_coroutine_switch().

virtio-balloon: Fix balloon not working correctly when hotplug memory
When do memory balloon, it takes the 'ram_size' as the VM's current ram size,
But 'ram_size' is the startup configured ram size, it does not take into
account the hotplugged memory.
As a result, the balloon result will be confused.
Steps to reproduce:
(1)Start VM: qemu -m size=1024,slots=4,maxmem=8G
(2)In VM: #free -m : 1024M
(3)qmp balloon 512M
(4)In VM: #free -m : 512M
(5)hotplug pc-dimm 1G
(6)In VM: #free -m : 1512M
(7)qmp balloon 256M
(8)In VM: #free -m :1256M
We expect the VM's available ram size to be 256M after 'qmp balloon 256M'
command, but VM's real available ram size is 1256M.
For "qmp balloon" is not performance critical code, we use function
'get_current_ram_size' to get VM's current ram size.

it crashes with:

XhcSyncTrsRing() [Pci/XhciDxe/XhciSched.c]
ASSERT (TrsRing != NULL) [4]
UsbEnumerateNewDev() in the USB bus driver issues a GET_DESCRIPTOR
request, in order to determine the number of configurations that the
endpoint supports. The requests consists of three stages (three TRBs),
setup, data, and status. The length of the response is determined in [1],
namely from the transfer event that the host controller generates in
response to the request's middle stage (ie. the data stage).
If the length of the answer is correct (a full GET_DESCRIPTOR request
takes 18 bytes), then the XHCI driver that underlies the USB bus driver
"snoops" (caches) the descriptor data for later [2].
Later, the USB bus driver sends a SET_CONFIG request. The underlying XHCI
driver allocates a transfer ring for the endpoint, relying on the data
snooped and cached in step [2].
Finally, the USB keyboard driver submits an asynchronous interrupt
transfer to manage the keyboard. As part of this it asserts [4] that the
ring has been allocated in step [3].
And this ASSERT() fires. The root cause can be found in the way QEMU
handles the initial GET_DESCRIPTOR request.
Again, that request consists of three stages (TRBs, Transfer Request
Blocks), "setup", "data", and "status". The XhcCreateTransferTrb()
function sets the IOC ("Interrupt on Completion") flag in each of these
TRBs.
According to the XHCI specification, the host controller shall generate a
Transfer Event in response to *each* individual TRB of the request that
had the IOC flag set. This means that QEMU should queue three events:
setup, data, and status, for edk2's XHCI driver.
However, QEMU only generates two events:
- one for the setup (ie. 1st) stage,
- another for the status (ie. 3rd) stage.
No event is generated for the middle (ie. data) stage. The loop in QEMU's
xhci_xfer_report() function runs three times, but due to the "reported"
variable, only the first and the last TRBs elicit events, the middle (data
stage) results in no event queued.
As a consequence:
- When handling the GET_DESCRIPTOR request, XhcCheckUrbResult() in [1]
does not update the response length from zero.
- XhcControlTransfer() thinks that the response is invalid (it has zero
length payload instead of 18 bytes), hence [2] is not reached; the
device descriptor is not stashed for later, and the number of possible
configurations is left at zero.
- When handling the SET_CONFIG request, (NumConfigurations == 0) from
above prevents the allocation of the endpoint's transfer ring.
- When the keyboard driver tries to use the endpoint, the ASSERT() blows
up.
The solution is to correct the emulation in QEMU, and to generate a
transfer event whenever IOC is set in a TRB.
The patch replaces
!reported && (IOC || foo) == !reported && IOC ||
!reported && foo
with
IOC || (!reported && foo) == IOC ||
!reported && foo
which only changes how
reported && IOC
is handled. (Namely, it now generates an event.)
Tested with edk2 built for "qemu-system-aarch64 -M virt" (ie.
"ArmVirtualizationQemu.dsc", aka "AAVMF"), and guest Linux.

spice: fix invalid memory access to vga.vram
vga_common_init() doesn't allow more than 256 MiB vram size and silently
shrinks any larger value. qxl_dirty_surfaces() used the unshrinked size
via qxl->shadow_rom.surface0_area_size when accessing the memory, which
resulted in segfault.
Add a workaround for this case and an assert if it happens again.
We have to bump the vga memory limit too, because 256 MiB wouldn't have
allowed 8k (it requires more than 128 MiB).
1024 MiB doesn't work, but 512 MiB seems fine.

bootdevice: check boot order argument validation before vm running
Either 'once' option or 'order' option can take effect for -boot at
the same time, that is say initial startup processing can check only
one. And pc.c's set_boot_dev() fails when its boot order argument
is invalid. This patch provide a solution fix this problem:
1. If "once" is given, register reset handler to restore boot order.
2. Pass the normal boot order to machine creation. Should fail when
the normal boot order is invalid.
3. If "once" is given, set it with qemu_boot_set(). Fails when the
once boot order is invalid.
4. Start the machine.
5. On reset, the reset handler calls qemu_boot_set() to restore boot
order. Should never fail.

halfword, rounds / and saturates each half word independently.
Add microcode helper functions:
* gen_maddsu_h/sus_h: multiply two halfwords left justified and add to the
first one word and subtract from the second one word
/ and saturate each resulting word independetly.
* gen_maddsum_h/sums_h: multiply two halfwords in q-format left justified
and add to the first one word and subtract from
the second one word / and saturate each resulting
word independetly.
* gen_maddsur32_h/32s_h: multiply two halfwords in q-format left justified
and add to the first one word and subtract from
the second one word, round both results / and
saturate each resulting word independetly.

Add helpers:

Note: madd instructions in the q format can behave strange, e.g.
0x1 + (0x80000000 * 0x80000000) << 1 for 32 bit signed values does not cause an
overflow on the guest, because all intermediate results should be handled as if
they are indefinitely precise. We handle this by inverting the overflow bit for
all cases: a + (0x80000000 * 0x80000000) << 1.

vfio-pci: Enable device request notification support
Linux v4.0-rc1 vfio-pci introduced a new virtual interrupt to allow
the kernel to request a device from the user. When signaled, QEMU
will by default attmempt to hot-unplug the device. This is a one-
shot attempt with the expectation that the kernel will continue to
poll for the device if it is not returned. Returning the device when
requested is the expected standard model of cooperative usage, but we
also add an option option to disable this feature. Initially this
opt-out is set as an experimental option because we really should
honor kernel requests for the device.

cpus: be more paranoid in avoiding deadlocks
For good measure, ensure that the following sequence:
thread 1 calls qemu_mutex_lock_iothread
thread 2 calls qemu_mutex_lock_iothread
VCPU thread are created
VCPU thread enters execution loop
results in the VCPU threads letting the other two threads run
and obeying iothread_requesting_mutex even if the VCPUs are
not halted. To do this, check iothread_requesting_mutex
before execution starts.

cpus: fix deadlock and segfault in qemu_mutex_lock_iothread
When two threads (other than the low-priority TCG VCPU thread)
are competing for the iothread lock, a deadlock can happen. This
is because iothread_requesting_mutex is set to false by the first
thread that gets the mutex, and then the VCPU thread might never
yield from the execution loop. If iothread_requesting_mutex is
changed from a bool to a counter, the deadlock is fixed.
However, there is another bug in qemu_mutex_lock_iothread that
can be triggered by the new call_rcu thread. The bug happens
if qemu_mutex_lock_iothread is called before the CPUs are
created. In that case, first_cpu is NULL and the caller
segfaults in qemu_mutex_lock_iothread. To fix this, just
do not do the kick if first_cpu is NULL.

virtio-scsi: Allocate op blocker reason before blocking
s->blocker is really only used in hw/scsi/virtio-scsi.c; the only places
where it is used in hw/scsi/virtio-scsi-dataplane.c is when it is
allocated and when it is freed. That does not make a whole lot of sense
(and is actually wrong because this leads to s->blocker potentially
being NULL when blk_op_block_all() is called in virtio-scsi.c), so move
the allocation and destruction of s->blocker to the device realization
and unrealization in virtio-scsi.c, respectively.
Case in point:
$ echo -e 'eject drv\nquit' | \
x86_64-softmmu/qemu-system-x86_64 \
-monitor stdio -machine accel=qtest -display none \
-object iothread,id=thr -device virtio-scsi-pci,iothread=thr \
-drive if=none,file=test.qcow2,format=qcow2,id=drv \
-device scsi-cd,drive=drv
Without this patch:
(qemu) eject drv
[1] 10102 done
10103 segmentation fault (core dumped)
With this patch:
(qemu) eject drv
Device 'drv' is busy: block device is in use by data plane

pci-hotplug-old: Has been dead for five major releases, bury
Commit 79ca616 (v1.6.0) accidentally disabled legacy x86-only HMP
commands pci_add, pci_del: it defined CONFIG_PCI_HOTPLUG only as make
variable, not as preprocessor macro, killing the code conditional on
defined(CONFIG_PCI_HOTPLUG_OLD).
In all this time, nobody reported the loss. I only noticed it when I
tried to test some error reporting change that forced me to touch this
old crap again.
Fun: git-log hw/pci/pci-hotplug-old.c shows our faith in the backward
compatibility god has been strong enough to sacrifice at its altar
about a dozen times, but not strong enough to even once verify the
legacy feature's still there, let alone works.

variant is not present, fallback to default blob.
With this change implement testing with a coldplugged
bridge.

pc: acpi-build: drop template patching and create Device(SMC) dynamically
patch moves SMC device into SSDT and creates it only
when device is present, which makes ACPI tables smaller
in default case when device is not present.
Also it fixes wrong IO range in CRS if "iobase"
property is set to a non default value.
PS:
Testing with XP shows that current default "iobase"
used SMC device conflicts with floppy controller IO,
but it's topic for another patch and I'd leave it
to SMC device author for resolving conflict.

Makefile: fix up parallel building under MSYS+MinGW
This patch enables parallel building of QEMU in MSYS+MinGW environment.
Currently an attempt to build QEMU in parallel fails on generation of
version.lo (and version.o too).
The cause of the failure is that when listing prerequisites "Makefile"
references "config-host.h" by absolute path in some rules and by relative
path in others. Make cannot figure out that these references points to the
same file which leads to the race: the generation of "version.*" which
requires "$(BUILD_DIR)/config-host.h" is launched in parallel with the
generation of "config-host.h" needed by other "Makefile" targets.
This patch removes "$(BUILD_DIR)/" prefix from corresponding prerequisite
of "version.*". There is no other prerequisites "$(BUILD_DIR)/config-host.h"
found.
Also note that not every version of MSYS is able to build QEMU in parallel,
see: "http://sourceforge.net/p/mingw/bugs/1950/". The suggested version is
1.0.17.

Currently the "platform-bus" device is included for all softmmu builds.
This bridge is intended for use on any platforms that require dynamic

future.
To avoid a not-very-useful entry appearing in "qemu -device ?" output on
other targets, this patch makes a specific config option for platform-bus
and enables it (for now) only on ppc configurations which include E500
and on ARM (which always includes the "virt" target).

Add specific config options for PCI-E bridges
The i82801b11, ioh3420 and xio3130 PCI Express devices are currently
included in the build unconditionally.
While they could theoretically appear on any target platform with PCI-E,
they're pretty unlikely to appear on platforms that aren't Intel derived.
Therefore, to avoid presenting unlikely-to-be-relevant devices to the user,
add config options to enable these components, and enable them by default
only on x86 and arm platforms.
(Note that this patch does include these for aarch64, via its inclusion of
arm-softmmu.mak).

block: Forbid bdrv_set_aio_context outside BQL
Even if the caller has both the old and the new AioContext's, there can
be a deadlock, due to the leading bdrv_drain_all.
Suppose there are four io threads (A, B, A0, B0) with A and B owning a
BDS for each (bs_a, bs_b); Now A wants to move bs_a to iothread A0, and
B wants to move bs_b to B0, at the same time:
iothread A iothread B
--------------------------------------------------------------------------
aio_context_acquire(A0) /* OK */ aio_context_acquire(B0) /* OK */
bdrv_set_aio_context(bs_a, A0) bdrv_set_aio_context(bs_b, B0)
-> bdrv_drain_all() -> bdrv_drain_all()
-> acquire A /* OK */ -> acquire A /* blocked */
-> acquire B /* blocked */ -> acquire B
... ...
Deadlock happens because A is waiting for B, and B is waiting for A.

scsi: give device a parent before setting properties
This mimics what is done in qdev_device_add, and lets the device be
freed in case something goes wrong. Otherwise, object_unparent returns
immediately without freeing the device, which is on the other hand left
in the parent bus's list of children.
scsi_bus_legacy_handle_cmdline then returns an error, and the HBA is
destroyed as well with object_unparent. But the lingering device that
was not removed in scsi_bus_legacy_add_drive cannot be removed now either,
and bus_unparent gets stuck in an infinite loop trying to empty the list
of children.
The right fix of course would be to assert in bus_add_child that the
device already has a bus, and remove the "safety net" that adds the
drive to the QOM tree in device_set_realized. I am not yet sure whether
that would entail changing all callers to qdev_create (as well as
isa_create and usb_create and the corresponding _try_create versions).

img_convert() and img_amend() use qemu_opts_do_parse(), which reports
errors with qerror_report_err(). Its error messages aren't helpful
here, the caller reports one that actually makes sense. Reproducer:
$ qemu-img convert -o backing_format=raw in.img out.img
qemu-img: Invalid parameter 'backing_format'
qemu-img: Invalid options for file format 'raw'
To fix, propagate errors through qemu_opts_do_parse(). This lifts the
error reporting into callers. Drop it from img_convert() and
img_amend(), keep it in qemu_chr_parse_compat(), bdrv_img_create().
Since I'm touching qemu_opts_do_parse() anyway, write a function
comment for it.

QemuOpts: Drop qemu_opt_set(), rename qemu_opt_set_err(), fix use
qemu_opt_set() is a wrapper around qemu_opt_set() that reports the
error with qerror_report_err().
Most of its users assume the function can't fail. Make them use
qemu_opt_set_err() with &error_abort, so that should the assumption
ever break, it'll break noisily.
Just two users remain, in util/qemu-config.c. Switch them to
qemu_opt_set_err() as well, then rename qemu_opt_set_err() to
qemu_opt_set().

pc: acpi-build: create CPU hotplug IO region dynamically
it replaces a static complied in DSDT MMIO region
for CPU hotplug with one created at runtime
leaving only truly static CPU hotplug related ASL
bits in DSDT.
It also puts CPU_HOTPLUG_RESOURCE_DEVICE into
PCI0 scope and reserves resources from it,
preparing for dropping manual hole punching
in PCI0._CRS.
Later it also would make easier to reuse current
ACPI CPU hotplug on other targets.
Also later it would be possible to move remaining
CPU hotplug ASL methods into build_ssdt() and
add all CPU hotplug related AML into SSDT only
when CPU hotplug is enabled, further reducing
ACPI tables blob if CPU hotplug isn't used.
impl. detail:
Windows XP can't handle /BSODs/ OperationRegion
declaration in DSDT when variable from SSDT is used
for specifying its address/length and also when
Field declared in DSDT with OperationRegion from
SSDT if DSDT is being parsed before SSDT.
But it works just fine when referencing named
fields from another table. Hence OperationRegion
and Field declaration are moved to SSDT to make
XP based editions work.
PS:
Later Windows editions seem to be fine with above
conditions.

acpi: include PkgLength size only when requested
Named/Reserved{Field} definition uses PkgLength [1] encoding to specify
field length, however it doesn't include size of PkgLength field itself,
while other block objects that have explicit length of its body account
for PkgLength size while encoding it [2].
This special casing isn't mentioned in ACPI spec, but that's what 'iasl'
compiles NamedField to so add extra argument to build_prepend_pkg_length()
to allow it handle the case.

acpi: introduce AML composer aml_append()
Adds for dynamic AML creation, which will be used
for piecing ASL/AML primitives together and hiding
from user/caller details about how nested context
should be closed/packed leaving less space for
mistakes and necessity to know how AML should be
encoded, allowing user to concentrate on ASL
representation instead.
For example it will allow to create AML like this:
init_aml_allocator();
...
Aml *scope = aml_scope("PCI0")
Aml *dev = aml_device("PM")
aml_append(dev, aml_name_decl("_ADR", aml_int(addr)))
aml_append(scope, dev);
...

For legacy machine types, rsdp is not in RAM, so we need a copy of rsdp

the array.

acpi-build: fix ACPI RAM management
This fixes multiple issues around ACPI RAM management:
RSDP and linker RAM aren't currently marked dirty
on update, so they won't be migrated correctly.
Let's handle all tables in the same way: set correct size (assert if
too big), update, mark RAM dirty.
This also drops assert checking that table size didn't change: table
size is fundamentally dynamic and depends on hw configuration,
just set the correct size and use that (memory core asserts if size is
too large).
This also means we can drop tracking table size, memory core does this
for us now.

acpi, piix4: Add unplug cb for piix4.
Memory and CPU hot unplug are both asynchronous procedures.
When the unplug operation happens, unplug request cb is called first.
And when guest OS finished handling unplug, unplug cb will be called
to do the real removal of device.
This patch adds hotunplug cb to piix4, which memory and CPU
hot unplug will use it.

qdev: Don't exit when running into bad -global
-global lets you set a nice booby-trap for yourself:
$ qemu-system-x86_64 -nodefaults -S -display none -usb -monitor stdio -global usb-mouse.usb_version=l
QEMU 2.1.94 monitor - type 'help' for more information
(qemu) device_add usb-mouse
Parameter 'usb_version' expects an int64 value or range
$ echo $?
1
Not nice. Until commit 3196270 we even abort()ed.
The same error triggers if you manage to screw up a machine type's
compat_props. To demonstrate, change HW_COMPAT_2_1's entry to
.driver = "usb-mouse",\
.property = "usb_version",\
.value = "1", \
Then run
$ qemu-system-x86_64 -usb -M pc-i440fx-2.1 -device usb-mouse
upstream-qemu: -device usb-mouse: Parameter 'usb_version' expects an int64 value or range
$ echo $?
1
One of our creatively cruel error messages.
Since this is actually a coding error, we *should* abort() here.
Replace the error by an assertion failure in this case.
But turn the fatal error into a mere warning when the faulty
GlobalProperty comes from the user. Looks like this:
$ qemu-system-x86_64 -nodefaults -S -display none -usb -monitor stdio -global usb-mouse.usb_version=l
QEMU 2.1.94 monitor - type 'help' for more information
(qemu) device_add usb-mouse
Warning: global usb-mouse.usb_version=l ignored (Parameter 'usb_version' expects an int64 value or range)
(qemu)
This is consistent with how we handle similarly unusable -global in
qdev_prop_check_globals().
You could argue that the error should make device_add fail. Would be
harder, because we're running within TypeInfo's instance_post_init()
method device_post_init(), which can't fail.

Implement DeviceClass methods realize() and unrealize() instead of

propagated properly, and QMP sends them instead of an unspecific
"Device initialization failed" error. Unrealize can't fail, so no
change there.
PCIDeviceClass is unchanged: it still provides init() and exit().
Therefore, device models' errors are still not propagated.

Make CONFIG_USER set apic-id before realizing the CPU (just like PC
already does), so we can simplify x86_cpu_initfn later. As there is no
CPU topology configuration in CONFIG_USER, just use cpu_index as the
APIC ID.

target-i386: Eliminate unnecessary get_cpuid_vendor() function
The function was used in only two places. In one of them, the function
made the code less readable by requiring temporary te[bcd]x variables.
In the other one we can simply inline the existing code.

target-i386: Simplify listflags() function
listflags() had lots of unnecessary complexity. Instead of printing to a
buffer that will be immediately printed, simply call the printing
function directly. Also, remove the fbits and flags arguments that were
always set to the same value. Also, there's no need to list the flags in
reverse order.

qapi-types: add C99 index names to arrays
It's not easy to figure out how monitor translates
strings: most QEMU code deals with translated indexes,
these are translated using _lookup arrays,
so you need to find the array name, and find the
appropriate offset.
This patch adds C99 indexes to lookup arrays, which makes it possible to
find the correct key using simple grep, and see that the matching is
correct at a glance.
Example:
Before:
const char *MigrationCapability_lookup[] = {
"xbzrle",
"rdma-pin-all",
"auto-converge",
"zero-blocks",
NULL,
};
After:
const char *MigrationCapability_lookup[] = {
[MIGRATION_CAPABILITY_XBZRLE] = "xbzrle",
[MIGRATION_CAPABILITY_RDMA_PIN_ALL] = "rdma-pin-all",
[MIGRATION_CAPABILITY_AUTO_CONVERGE] = "auto-converge",
[MIGRATION_CAPABILITY_ZERO_BLOCKS] = "zero-blocks",
[MIGRATION_CAPABILITY_MAX] = NULL,
};

A number of ARM embedded boards include EHCI USB host controllers which
appear as directly mapped devices, rather than sitting on a PCI bus.
At present code to emulate such devices is included whenever EHCI support
is included. This patch adjusts teh config options to only include them
in builds targetting ARM by default.

usb: Suppress bogus error when automatic usb-hub creation fails
USBDevice's realize method usb_qdev_realize() automatically creates a
usb-hub when only one port is left. Creating devices in realize
methods is questionable, but works.
If usb-hub creation fails, an error is reported to stderr, but the
failure is otherwise ignored. We then create the actual device using
the last port, which may well succeed.
Example:
$ qemu -nodefaults -S -display none -machine usb=on -monitor stdio
QEMU 2.2.50 monitor - type 'help' for more information
(qemu) device_add usb-mouse
[Repeat 36 times]
(qemu) info usb
Device 0.0, Port 1, Speed 12 Mb/s, Product QEMU USB Mouse
Device 0.0, Port 2, Speed 12 Mb/s, Product QEMU USB Hub
Device 0.0, Port 2.1, Speed 12 Mb/s, Product QEMU USB Mouse
[More mice and hubs omitted...]
Device 0.0, Port 2.8.8.8.8.7, Speed 12 Mb/s, Product QEMU USB Mouse
(qemu) device_add usb-mouse
usb hub chain too deep
Failed to initialize USB device 'usb-hub'
(qemu) info usb
[...]
Device 0.0, Port 2.8.8.8.8.7, Speed 12 Mb/s, Product QEMU USB Mouse
Device 0.0, Port 2.8.8.8.8.8, Speed 12 Mb/s, Product QEMU USB Mouse
Despite the "Failed" message, the command actually succeeded.
In QMP, it's worse. When adding the 37th mouse via QMP, the command
fails with
{"error": {"class": "GenericError", "desc": "usb hub chain too deep"}}
Additionally, "Failed to initialize USB device 'usb-hub'" is reported
on stderr. Despite the command failure, the device was created. This
is wrong.
Fix by avoiding qdev_init() for usb-hub creation, so we can ignore
errors cleanly.

usb: Improve -usbdevice error reporting a bit
Most LegacyUSBFactory usbdevice_init() methods realize with
qdev_init_nofail(), even though their caller usbdevice_create() can
handle failure. Okay if it really can't fail (I didn't check), but
somewhat brittle.
usb_msd_init() and usb_bt_init() call qdev_init(). The latter
additionally reports an error when qdev_init() fails.
Realization failure produces multiple error reports: a specific one
from qdev_init(), and generic ones from usb_bt_init(),
usb_create_simple(), usbdevice_create() and usb_parse().
Remove realization from the usbdevice_init() methods. Realize in
usbdevice_create(), and produce exactly one error message there. You
still get another one from usb_parse().

monitor: Clean up around monitor_handle_fd_param()
monitor_handle_fd_param() is a wrapper around
monitor_handle_fd_param2() that feeds errors to qerror_report_err()
instead of returning them. qerror_report_err() is inappropriate in
many contexts. monitor_handle_fd_param() looks simpler than
monitor_handle_fd_param2(), which tempts use. Remove the temptation:
drop the wrapper and open-code the (trivial) error handling instead.
Replace the open-coded qerror_report_err() by error_report_err() in
places that already use error_report(). Turns out that's everywhere.
While there, rename monitor_handle_fd_param2() to monitor_fd_param().

vhost-scsi: Improve error reporting for invalid vhostfd
We get two error messages: one from monitor_handle_fd_param2(), and
another one from vhost_scsi_realize(). The second one gets suppressed
in QMP context.
That's because monitor_handle_fd_param() calls qerror_report_err().
Calling qerror_report_err() is always inappropriate in realize
methods, because it doesn't return the Error object. It either
reports the error to stderr or the human monitor, or it stores it in
the QMP monitor, where it makes the QMP command fail even when the
realize method ignores the error and succeeds. Fortunately,
vhost_scsi_realize() doesn't do that.
Fix by switching to monitor_handle_fd_param2().

An Address Space Control Element (ASCE) is only the very first unit of

So let's call the relevant variable pt_entry instead of asce in

s390x/mmu: Fix the handling of the table levels
The current code used a wrong and very confusing way of dealing with
the table levels by introducing a "fake level above current". However,
the real problem was simply that the checks for the region/segment
invalid bit and for the matching region/segment level was done at the
wrong spot in the code - it has to be done after the first table entry
has been looked up instead (e.g. there is also no "invalid" bit in the
ASCE itself and the current "level" has to be the same as the level in
the entry that we just looked up).
Also the entries for the segment table are quite a bit different compared
to the region table entries. So this patch moves the related code into the
function mmu_translate_segment() to make it clear at which table level we
currently are and to get rid of the ugly switch-statement in the function
mmu_translate_region().

qga: implement file commands for Windows guest
The following commands are implemented:
- guest_file_open
- guest_file_close
- guest_file_write
- guest_file_read
- guest_file_seek
- guest_file_flush
Motivation is quite simple: Windows guests should be supported with the
same set of features as Linux one. Also this patch is a prerequisite for
Windows guest-exec command support.

utils: drop strtok_r from envlist_parse
The problem is that mingw 4.9.1 fails to compile the code with the
following warning:
/mingw/include/string.h:88:9: note: previous declaration of 'strtok_r'
was here
char *strtok_r(char * __restrict__ _Str,
const char * __restrict__ _Delim,
char ** __restrict__ __last);
/include/sysemu/os-win32.h:83:7: warning: redundant redeclaration of
'strtok_r' [-Wredundant-decls]
char *strtok_r(char *str, const char *delim, char **saveptr);
The problem is that compiles just fine on previous versions of mingw.
Compiler version check here is not a good idea. Though fortunately
strtok_r is used only once in the code and we could simply rewrite
the code without it.

qga: add guest-set-user-password command
Add a new 'guest-set-user-password' command for changing the password
of guest OS user accounts. This command is needed to enable OpenStack
to support its API for changing the admin password of guests running
on KVM/QEMU. It is not practical to provide a command at the QEMU
level explicitly targetting administrator account password change
only, since different guest OS have different names for the admin
account. While UNIX systems use 'root', Windows systems typically
use 'Administrator' and even that can be renamed. Higher level apps
like OpenStack have the ability to figure out the correct admin
account name since they have info that QEMU/libvirt do not.
The command accepts either the clear text password string, encoded
in base64 to make it 8-bit safe in JSON:
$ echo -n "123456" | base64
MTIzNDU2
$ virsh -c qemu:///system qemu-agent-command f21x86_64 \
'{ "execute": "guest-set-user-password",
"arguments": { "crypted": false,
"username": "root",
"password": "MTIzNDU2" } }'
{"return":{}}
Or a password that has already been run though a crypt(3) like
algorithm appropriate for the guest, again then base64 encoded:
$ echo -n '$6$n01A2Tau$e...snip...DfMOP7of9AJ1I8q0' | base64
JDYkb...snip...YT2Ey
$ virsh -c qemu:///system qemu-agent-command f21x86_64 \
'{ "execute": "guest-set-user-password",
"arguments": { "crypted": true,
"username": "root",
"password": "JDYkb...snip...YT2Ey" } }'
NB windows support is desirable, but not implemented in this
patch.

Convert ram_list to RCU
Allow "unlocked" reads of the ram_list by using an RCU-enabled QLIST.
The ramlist mutex is kept. call_rcu callbacks are run with the iothread
lock taken, but that may change in the future. Writers still take the
ramlist mutex, but they no longer need to assume that the iothread lock
is taken.
Readers of the list, instead, no longer require either the iothread
or ramlist mutex, but they need to use rcu_read_lock() and
rcu_read_unlock().
One place in arch_init.c was downgrading from write side to read side
like this:
qemu_mutex_lock_iothread()
qemu_mutex_lock_ramlist()
...
qemu_mutex_unlock_iothread()
...
qemu_mutex_unlock_ramlist()
and the equivalent idiom is:
qemu_mutex_lock_ramlist()
rcu_read_lock()
...
qemu_mutex_unlock_ramlist()
...
rcu_read_unlock()

qemu-io: Use BlockBackend
qemu-io should behave like a guest, therefore it should use BlockBackend
to access the block layer.
There are a couple of places where that is infeasible: First, the
bdrv_debug_* functions could theoretically be mirrored in the
BlockBackend, but since these are functions internal to the block layer,
they should not be visible externally (qemu-io as a test tool is exempt
from this).
Second, bdrv_get_info() and bdrv_get_specific_info() work on a single
BDS alone, therefore they should stay BDS-specific.
Third, bdrv_is_allocated() mainly works on a single BDS as well. Some
data may be passed through from the BDS's file (if sectors which are
apparently allocated in the file are not really allocated there but just
zero).
[Fixed conflicts around block_acct_start() usage from Fam Zheng's
"qemu-io: Account IO by aio_read and aio_write" commit. Use
BlockBackend and blk_get_stats() instead of BlockDriverState.

qemu-io: Remove "growable" option
Remove "growable" option from the "open" command and from the qemu-io
command line. qemu-io is about to be converted to BlockBackend which
will make sure that no request exceeds the image size, so the only way
to keep "growable" would be to use BlockBackend if it is not given and
to directly access the BDS if it is.
qemu-io is a debugging tool, therefore removing a rarely used option
will have only a very small impact, if any. There was only one
qemu-iotest which used the option; since it is not critical, this patch
just removes it.

block: Add blk_new_open()
blk_new_with_bs() creates a BlockBackend with an empty BlockDriverState
attached to it. Empty BDSs are not nice, therefore add an alternative
function which combines blk_new_with_bs() with bdrv_open().
Note: In contrast to bdrv_open() which takes a BlockDriver parameter,
blk_new_open() does not take such a parameter. This is because
bdrv_open() opens a BlockDriverState, therefore it is natural to be able
to set the BlockDriver for that BDS. The fact that bdrv_open() can open
more than a single BDS is merely some form of a byproduct.
blk_new_open() on the other hand is intended to be used to create a
whole tree of BlockDriverStates. Therefore, setting a single BlockDriver
does not make much sense. Instead, the drivers to be used for each of
the nodes must be configured through the "options" QDict; including the
driver of the root BDS.

qemu-iotests: Add 093 for IO throttling
This case utilizes qemu-io command "aio_{read,write} -q" to verify the
effectiveness of IO throttling options.
It's implemented by driving the vm timer from qtest protocol, so the
throttling timers are signaled with determinied time duration. Then we
verify the completed IO requests are within 10% error of bps and iops
limits.
"null" protocol is used as the disk backend so that no actual disk IO is
performed on host, this will make the blockstats much more
deterministic. Both "null-aio" and "null-co" are covered, which is also
a simple cross validation test for the driver code.

qtest: Fix deadloop by running main loop AIO context's timers
qemu_clock_run_timers() only takes care of main_loop_tlg, we shouldn't
forget aio timer list groups.
Currently, the qemu_clock_deadline_ns_all (a few lines above) counts all
the timergroups of this clock type, including aio tlg, but we don't fire
them, so they are never cleared, which makes a dead loop.
For example, this function hangs when trying to drive throttled block
request queue with qtest clock_step.

savevm: Improve error message for blocked migration
If an internal snapshot can't be saved because migration is blocked
(most commonly probably because of AHCI), we had a really bad error
message:
$ echo -e "savevm foo\nquit" | qemu -M q35 /tmp/test.qcow2 -monitor stdio
QEMU 2.2.50 monitor - type 'help' for more information

This patch converts qemu_savevm_state() to the Error infrastructure so
that a useful error pointing to the problematic device is produced now:

We find the nbd_recv_coroutines_enter_all function (triggered by a cancel
command or a network connection breaking down) will enter a coroutine which
is waiting for the sending lock. If the lock is still held by another coroutine,
the entering coroutine will be added into the co_queue again. Latter, when the
lock is released, a coroutine re-enter error will occur.
This bug can be fixed simply by delaying the setting of recv_coroutine as
suggested by paolo. After applying this patch, we have tested the cancel
operation in mirror phase looply for more than 5 hous and everything is fine.
Without this patch, a coroutine re-enter error will occur in 5 minutes.

ahci_io is a wrapper around ahci_guest_io that takes a pointer to host

after a read, the guest data will be in a host buffer, and for a write,
the data will be transmitted to guest memory prior to the block operation.
Now that we have all the syntactic sugar functions in place for AHCI,
we can convert the identify test to be very, very short.

libqos/ahci: Add command header helpers
Adds command header helper functions:
-ahci_command_header_set
-ahci_command_header_get,
-ahci_command_destroy, and
-ahci_cmd_pick
These helpers help to quickly manage the command header information in
the AHCI device.
ahci_command_header_set and get will store or retrieve an AHCI command
header, respectively.
ahci_cmd_pick chooses the first available but least recently used
command slot to allow us to cycle through the available command slots.
ahci_command_destroy obliterates all information contained within a
given slot's command header, and frees its associated command table,
but not its DMA buffer!
Lastly, the command table pointer fields (dba and dbau) are merged into
a single 64bit value to make managing 64bit tests simpler.

qtest/ahci: rename 'Command' to 'CommandHeader'
The structure name is a bit of a misnomer; the structure currently named
command is actually the commandheader. A future patch in this series
will add an actual "Command" structure, so we'll rename it now before the
rest of the functions in this series try to use it.
In addition, rename the "b1" and "b2" fields
to be a unified uint16_t named "flags."

dataplane: endianness-aware accesses
The vring.c code currently assumes that guest and host endianness match,
which is not true for a number of cases:
- emulating targets with a different endianness than the host
- bi-endian targets, where the correct endianness depends on the virtio
device
- upcoming support for the virtio-1 standard mandates little-endian
accesses even for big-endian targets and hosts
Make sure to use accessors that depend on the virtio device.
Note that dataplane now needs to be built per-target.

qtest/ahci: Store hba_base in AHCIQState
Store the HBA memory base address in the new state object, to simplify
function prototypes and encourage a more functional testing style.
This causes a lot of churn, but this patch is as "simplified" as I could
get it to be. This patch is therefore fairly mechanical and straightforward:
Any case where we pass "hba_base" has been consolidated into the AHCIQState
object and we pass the one unified parameter.
Any case where we reference "ahci" and "hba_state" have been modified to use
"ahci->dev" for the PCIDevice and "ahci->hba_state" to get at the base memory
address, accordingly.
Notes:
- A needless return is removed from start_ahci_device.
- For ease of reviewing, this patch can be reproduced (mostly) by:
# Replace (ahci, hba_base) prototypes with unified parameter
's/(QPCIDevice \*ahci, void \*\?\*hba_base/(AHCIQState *ahci/'
# Replace (ahci->dev, hba_base) calls with unified parameter
's/(ahci->dev, &\?hba_base)/(ahci)/'
# Replace calls to PCI config space using "ahci" with "ahci->dev"
's/qpci_config_\(read\|write\)\(.\)(ahci,/qpci_config_\1\2(ahci->dev,/'
After these, the remaining differences are easy to review by hand.

libqos: Update QGuestAllocator to be opaque
To avoid the architecture-specific implementations of the generic qtest
allocator having to know about fields within the allocator, add a
page_size setter method for users or arch specializations to use.
The allocator will assume a default page_size for general use, but it
can always be overridden.
Since this was the last instance of code directly using properties of the
QGuestAllocator object directly, modify the type to be opaque and move
the structure inside of malloc.c.
mlist_new, which was previously exported, is made static local to malloc.c,
as it has no external users.

libqos: create libqos.c
The intent of this file is to serve as a misc. utilities file to be
shared amongst tests that are utilizing libqos facilities.
In a later patch, migration test helpers will be added to libqos.c that
will allow simplified testing of migration cases where libqos is
"Just Enough OS" for migrations testing.
The addition of the AHCIQState structure will also allow us to eliminate
global variables inside of qtests to manage allocators and test instances
in a better, more functional way.
libqos.c:
- Add qtest_boot
- Add qtest_shutdown
libqos.h:
- Create QOSState structure for allocator and QTestState.
ahci-test.c:
- Move qtest_boot and qtest_shutdown to libqos.c/h
- Create AHCIQState to interface with new qtest_boot/shutdown prototypes
- Modify tests slightly to use new types.
For now, the new object file is only linked to ahci-test, because it still
relies on pc architecture specific code in libqos. The next two patches will
reorganize the code to be more general.

s390x/ipl: drop reipl parameters on resets
Whenever a reboot initiated by the guest is done, the reipl parameters should
remain valid. The disk configured by the guest is to be used for
ipl'ing. External reboot/reset request (e.g. via virsh reset guest) should
completely reset the guest to the initial state, and therefore also reset the
reipl parameters, resulting in an ipl behaviour of the initially configured
guest. This could be an external kernel or a disk.

To support dynamically updating the IPL device from inside the KVM
guest on the s390 platform, DIAG 308 instruction is intercepted
in QEMU to handle the request.
Subcode 5 allows to specify a new boot device, which is saved for
later in the s390_ipl device. This also allows to switch from an
external kernel to a boot device.
Subcode 6 retrieves boot device configuration that has been previously
set.

target-arm: A64: Fix handling of rotate in logic_imm_decode_wmask
The code in logic_imm_decode_wmask attempts to rotate a mask
value within the bottom 'e' bits of the value with
mask = (mask >> r) | (mask << (e - r));
This has two issues:
* if the element size is 64 then a rotate by zero results
in a shift left by 64, which is undefined behaviour
* if the element size is smaller than 64 then this will
leave junk in the value at bit 'e' and above, which is
not valid input to bitfield_replicate(). As it happens,
the bits at bit 'e' to '2e - r' are exactly the ones
which bitfield_replicate is going to copy in there,
so this isn't a "wrong code generated" bug, but it's
confusing and if we ever put an assert in
bitfield_replicate it would fire on valid guest code.
Fix the former by not doing anything if r is zero, and
the latter by masking with bitmask64(e).

arm: Add PCIe host bridge in virt machine
Now that we have a working "generic" PCIe host bridge driver, we can plug
it into ARM's virt machine to always have PCIe available to normal ARM VMs.

pci: Add generic PCIe host bridge
With simple exposure of MMFG, ioport window, mmio window and an IRQ line we
can successfully create a workable PCIe host bridge that can be mapped anywhere
and only needs to get described to the OS using whatever means it likes.
This patch implements such a "generic" host bridge. It handles 4 legacy IRQ
lines. MSIs need to be handled external to the host bridge.
This device is particularly useful for the "pci-host-ecam-generic" driver in
Linux.

vfio: Use vfio type1 v2 IOMMU interface
The difference between v1 and v2 is fairly subtle, simply more
deterministic behavior for unmaps. The v1 interface allows the user
to attempt to unmap sub-regions of previous mappings, returning
success with zero size if unable to comply. This was a reflection of
the underlying IOMMU API. The v2 interface requires that the user
may only unmap fully contained mappings, ie. an unmap cannot intersect
or bisect a previous mapping, but may cover multiple mappings. QEMU
never made use of the sub-region v1 support anyway, so we can support
either v1 or v2. We'll favor v2 since it's newer.

vfio: unmap and free BAR data in instance_finalize
In the case of VFIO, the unrealize callback is too early to munmap the
BARs. The munmap must be delayed until memory accesses are complete.
To do this, split vfio_unmap_bars in two. The removal step, now called
vfio_unregister_bars, remains in vfio_exitfn. The reclamation step
is vfio_unmap_bars and is moved to the instance_finalize callback.
Similarly, quirk MemoryRegions have to be removed during
vfio_unregister_bars, but freeing the data structure must be delayed
to vfio_unmap_bars.

vfio: free dynamically-allocated data in instance_finalize
In order to enable out-of-BQL address space lookup, destruction of
devices needs to be split in two phases.
Unrealize is the first phase; once it complete no new accesses will
be started, but there may still be pending memory accesses can still
be completed.
The second part is freeing the device, which only happens once all memory
accesses are complete. At this point the reference count has dropped to
zero, an RCU grace period must have completed (because the RCU-protected
FlatViews hold a reference to the device via memory_region_ref). This is
when instance_finalize is called.
Freeing data belongs in an instance_finalize callback, because the
dynamically allocated memory can still be used after unrealize by the
pending memory accesses.
This starts the process by creating an instance_finalize callback and
freeing most of the dynamically-allocated data in instance_finalize.
Because instance_finalize is also called on error paths or also when
the device is actually not realized, the common code needs some changes
to be ready for this. The error path in vfio_initfn can be simplified too.

vfio: cleanup vfio_get_device error path, remove vfio_populate_device callback
Now that vfio_put_base_device is called unconditionally at instance_finalize
time, it can be called twice if vfio_populate_device fails. This works
but it is slightly harder to follow.
Change vfio_get_device to not touch the vbasedev struct until it will
definitely succeed, moving the vfio_populate_device call back to vfio-pci.
This way, vfio_put_base_device will only be called once.

memory: unregister AddressSpace MemoryListener within BQL
address_space_destroy_dispatch is called from an RCU callback and hence
outside the iothread mutex (BQL). However, after address_space_destroy
no new accesses can hit the destroyed AddressSpace so it is not necessary
to observe changes to the memory map. Move the memory_listener_unregister
call earlier, to make it thread-safe again.

translate-all: Use g_try_malloc() for dynamic translator buffer
The USE_MMAP code can fail, and the caller handles the failure
already. Let the !USE_MMAP code fail as well, for consistency.

util/uri: URI member path can be null, compare more carfully
uri_resolve_relative() calls strcmp(bas->path, ref->path). However,
either argument could be null! Evidence: the code checks for null
after the comparison. Spotted by Coverity.
I suspect this was screwed up when we stole the code from libxml2.
There the conditional reads
xmlStrEqual((xmlChar *)bas->path, (xmlChar *)ref->path)
with
int
xmlStrEqual(const xmlChar *str1, const xmlChar *str2) {
if (str1 == str2) return(1);
if (str1 == NULL) return(0);
if (str2 == NULL) return(0);
do {
if (*str1++ != *str2) return(0);
} while (*str2++);
return(1);
}
Fix by replicating libxml2's logic faithfully.

vl: Fix bogus error message for implied mon ID clashing
monitor_parse() desugars --monitor, --qmp and -qmp-pretty to --mon.
The ID it picks can clash with a user-specified ID. When it happens,
the error message is misleading.
Reproducer:
$ qemu --mon id=compat_monitor0 --monitor stdio
Message before the patch:
duplicate chardev: compat_monitor0
There's no "duplicate chardev" here. The problem is a duplicate
monitor ID. Moreover, the message provides no clue which option
caused the problem. The patch changes the message to:
qemu: --monitor stdio: Duplicate ID 'compat_monitor0' for mon
monitor_parse() is also used for creating a default monitor, but
that's not done when the user specifies a monitor, so an ID clash is
impossible then.

block: Give always priority to unused entries in the qcow2 L2 cache
The current algorithm to replace entries from the L2 cache gives
priority to newer hits by dividing the hit count of all existing
entries by two everytime there is a cache miss.
However, if there are several cache misses the hit count of the
existing entries can easily go down to 0. This will result in those
entries being replaced even when there are others that have never been
used.
This problem is more noticeable with larger disk images and cache
sizes, since the chances of having several misses before the cache is
full are higher.

nbd: fix max_discard/max_transfer_length
nbd_co_discard calls nbd_client_session_co_discard which uses uint32_t
as the length in bytes of the data to discard due to the following
definition:
struct nbd_request {
uint32_t magic;
uint32_t type;
uint64_t handle;
uint64_t from;
uint32_t len; <-- the length of data to be discarded, in bytes
} QEMU_PACKED;
Thus we should limit bl_max_discard to UINT32_MAX >> BDRV_SECTOR_BITS to
avoid overflow.
NBD read/write code uses the same structure for transfers. Fix
max_transfer_length accordingly.

nbd: Improve error messages
This patch makes use of the Error object for nbd_receive_negotiate() so
that errors during negotiation look nicer.
Furthermore, this patch adds an additional error message if the received
magic was wrong, but would be correct for the other protocol version,
respectively: So if an export name was specified, but the NBD server
magic corresponds to an old handshake, this condition is explicitly
signaled to the user, and vice versa.
As these messages are now part of the "Could not open image" error
message, additional filtering has to be employed in iotest 083, which
this patch does as well.

iotests: Fix 104 for NBD
_make_test_img sets up an NBD server, _cleanup_test_img shuts it down;
thus, _cleanup_test_img has to be called before _make_test_img is
invoked another time.
Furthermore, the pipe through _filter_test_img was unnecessary;
_make_test_img already takes care of that.
And finally, a filter is added to _filter_img_info to replace
"nbd://127.0.0.1:10810" by "TEST_DIR/t.IMGFMT", since the former is the
way to express the full image path (normally the latter) for NBD tests.

Note that one case which failed before is now successful: Disconnect

block/dmg: support bzip2 block entry types
This patch adds support for bzip2-compressed block entries as introduced
with OS X 10.4 (source: https://en.wikipedia.org/wiki/Apple_Disk_Image).
It was tested against a 5.2G "OS X Yosemite" installation image which
stores the BLXX block in the XML property list (instead of resource
forks) and has over 5k chunks.
New configure entries are added (--enable-bzip2 / --disable-bzip2) to
control inclusion of bzip2 functionality (which requires linking against
libbz2). The help message suggests that this option is needed for DMG
files, but the tests are generic enough that other parts of QEMU can use
bzip2 if needed.
The identifiers are based on http://newosxbook.com/DMG.html.
The decompression routines are based on the zlib case, but as there is
no way to reset the decompression state (unlike zlib), memory is
allocated and deallocated for every decompression. This should not be
problematic as the decompression takes most of the time and as blocks
are typically about/over 1 MiB in size, only one allocation is done
every 2000 sectors.

The implementation of dmg2img (from vu1tur) does not base the output
sector on the location of the terminator (0xffffffff) either so it
should be safe to drop this dependency on the previous state.
(It makes somehow makes sense, a terminator should halt further
processing of a block and is perhaps used to preallocate some space.)

block/dmg: fix sector data offset calculation
This patch addresses two issues:
- The data fork offset was not taken into account, resulting in failure
to read an InstallESD.dmg file (5164763151 bytes) which had a
non-zero DataForkOffset field.
- The offset of the previous block ("partition") was unconditionally
added to the current block because older files would start the input
offset of a new block at zero. Newer files (including vlc-2.1.5.dmg,
tuxpaint-0.9.15-macosx.dmg and OS X Yosemite [MAS].dmg) failed in
reads because these files have chunk offsets, relative to the begin
of a data fork.
Now the data offset of the mish is taken into account. While we could
check that the data_offset is within the data fork, let's not do that
here as it would only result in parse failures on invalid files (rather
than gracefully handling such bad files). dmg_read will error out if
the offset is incorrect.

block/dmg: extract processing of resource forks
Besides the offset, also read the resource length. This length is now
used in the extracted function to verify the end of the resource fork
against "count" from the resource fork.
Instead of relying on the value of offset to conclude whether the
resource fork is available or not (info_begin==0), check the
rsrc_fork_length instead. This would allow a dmg file to begin with a
resource fork. This seemingly unnecessary restriction was found while
trying to craft a DMG file by hand.
Other changes:
- Do not require resource data offset to be 0x100 (but check that it
is within bounds though).
- Further improve boundary checking (resource data must be within
the resource fork).
- Use correct value for resource data length (spotted by John Snow)
- Consider the resource data offset when determining info_end.
This fixes an EINVAL on the tuxpaint dmg example.

block/dmg: extract mish block decoding functionality
Extract the mish block decoder such that this can be used for other
formats in the future. A new DmgHeaderState struct is introduced to
share state while decoding.
The code is kept unchanged as much as possible, a "fail" label is added
for example where a simple return would probably do. In dmg_open, the
variable "tmp" is renamed to "rsrc_data_offset" for clarity and comments
have been added explaining various data.
Note that this patch has one subtle difference with the previous
version which should not affect functionality. In the previous code,
the end of a resource was inferred from the mish block (the offsets
would be increased by the fields). In this patch, the resource length
is used instead to avoid the need to rely on the previous offsets.

block/dmg: properly detect the UDIF trailer
DMG files have a variable length with a UDIF trailer at the end of a
file. This UDIF trailer is essential as it describes the contents of
the image. At the moment however, the start of this trailer is almost
always incorrect as bdrv_getlength() returns a multiple of the block
size (rounded up). This results in a failure to recognize DMG files,
resulting in Invalid argument (EINVAL) errors.
As there is no API to retrieve the real file size, look for the magic
header in the last two sectors to find the start of this 512-byte UDIF
trailer (the "koly" block).
The resource fork offset ("info_begin") has its offset adjusted as the
initial value of offset does not mean "end of file" anymore, but "begin
of UDIF trailer".

block: add event when disk usage exceeds threshold
Managing applications, like oVirt (http://www.ovirt.org), make extensive
use of thin-provisioned disk images.
To let the guest run smoothly and be not unnecessarily paused, oVirt sets
a disk usage threshold (so called 'high water mark') based on the occupation
of the device, and automatically extends the image once the threshold
is reached or exceeded.
In order to detect the crossing of the threshold, oVirt has no choice but
aggressively polling the QEMU monitor using the query-blockstats command.
This lead to unnecessary system load, and is made even worse under scale:
deployments with hundreds of VMs are no longer rare.
To fix this, this patch adds:
* A new monitor command `block-set-write-threshold', to set a mark for
a given block device.
* A new event `BLOCK_WRITE_THRESHOLD', to report if a block device
usage exceeds the threshold.
* A new `write_threshold' field into the `BlockDeviceInfo' structure,
to report the configured threshold.
This will allow the managing application to use smarter and more
efficient monitoring, greatly reducing the need of polling.
[Updated qemu-iotests 067 output to add the new 'write_threshold'
property. --Stefan]

for those requests. Secondly, this is required to switch to
direct invocation of coroutines which is planned at a later stage.

block: use fallocate(FALLOC_FL_PUNCH_HOLE) & fallocate(0) to write zeroes
This sequence works efficiently if FALLOC_FL_ZERO_RANGE is not supported.
Unfortunately, FALLOC_FL_ZERO_RANGE is supported on really modern systems
and only for a couple of filesystems. FALLOC_FL_PUNCH_HOLE is much more
mature.
The sequence of 2 operations FALLOC_FL_PUNCH_HOLE and 0 is necessary due
to the following reasons:
- FALLOC_FL_PUNCH_HOLE creates a hole in the file, the file becomes
sparse. In order to retain original functionality we must allocate
disk space afterwards. This is done using fallocate(0) call
- fallocate(0) without preceeding FALLOC_FL_PUNCH_HOLE will do nothing
if called above already allocated areas of the file, i.e. the content
will not be zeroed
This should increase the performance a bit for not-so-modern kernels.

block/raw-posix: call plain fallocate in handle_aiocb_write_zeroes
There is a possibility that we are extending our image and thus writing
zeroes beyond the end of the file. In this case we do not need to care
about the hole to make sure that there is no data in the file under
this offset (pre-condition to fallocate(0) to work). We could simply call
fallocate(0).
This improves the performance of writing zeroes even on really old
platforms which do not have even FALLOC_FL_PUNCH_HOLE.
Before the patch do_fallocate was used when either
CONFIG_FALLOCATE_PUNCH_HOLE or CONFIG_FALLOCATE_ZERO_RANGE are defined.
Now the story is different. CONFIG_FALLOCATE is defined when Linux
fallocate is defined, posix_fallocate is completely different story
(CONFIG_POSIX_FALLOCATE). CONFIG_FALLOCATE is mandatory prerequite
for both CONFIG_FALLOCATE_PUNCH_HOLE and CONFIG_FALLOCATE_ZERO_RANGE
thus we are on the safe side.

atapi migration: Throw recoverable error to avoid recovery
(With the previous atapi_dma flag recovery)
If migration happens between the ATAPI command being written and the
bmdma being started, the DMA is dropped. Eventually the guest times
out and recovers, but that can take many seconds.
(This is rare, on a pingpong reading the CD continuously I hit
this about ~1/30-1/50 migrates)
I don't think we've got enough state to be able to recover safely
at this point, so I throw a 'medium error, no seek complete'
that I'm assuming guests will try and recover from an apparently
dirty CD.
OK, it's a hack, the real solution is probably to push a lot of
ATAPI state into the migration stream, but this is a fix that
works with no stream changes. Tested only on Linux (both RHEL5
(pre-libata) and RHEL7).

Restore atapi_dma flag across migration
If a migration happens just after the guest has kicked
off an ATAPI command and kicked off DMA, we lose the atapi_dma
flag, and the destination tries to complete the command as PIO
rather than DMA. This upsets Linux; modern libata based kernels
stumble and recover OK, older kernels end up passing bad data
to userspace.

rtl8139: simplify timer logic
Pavel Dovgalyuk reports that TimerExpire and the timer are not restored
correctly on the receiving end of migration.
It is not clear to me whether this is really the case, but we can take
the occasion to get rid of the complicated code that computes PCSTimeout
on the fly upon changes to IntrStatus/IntrMask. Just always keep a
timer running, it will fire every ~130 seconds at most if the interrupt
is masked with TimerInt != 0.
This makes rtl8139_set_next_tctr_time idempotent (when the virtual clock
is stopped between two calls, as is the case during migration).
Tested with Frediano's qtest.

migration: Append JSON description of migration stream
One of the annoyances of the current migration format is the fact that
it's not self-describing. In fact, it's not properly describing at all.
Some code randomly scattered throughout QEMU elaborates roughly how to
read and write a stream of bytes.
We discussed an idea during KVM Forum 2013 to add a JSON description of
the migration protocol itself to the migration stream. This patch
adds a section after the VM_END migration end marker that contains
description data on what the device sections of the stream are composed of.
This approach is backwards compatible with any QEMU version reading the
stream, because QEMU just stops reading after the VM_END marker and ignores
any data following it.
With an additional external program this allows us to decipher the
contents of any migration stream and hopefully make migration bugs easier
to track down.

qemu-file: Add fast ftell code path
For ftell we flush the output buffer to ensure that we don't have anything
lingering in our internal buffers. This is a very safe thing to do.
However, with the dynamic size measurement that the dynamic vmstate
description will bring this would turn out quite slow.
Instead, we can fast path this specific measurement and just take the
internal buffers into account when telling the kernel our position.
I'm sure I overlooked some corner cases where this doesn't work, so
instead of tuning the safe, existing version, this patch adds a fast
variant of ftell that gets used by the dynamic vmstate description code
which isn't critical when it fails.

QJSON: Add JSON writer
To support programmatic JSON assembly while keeping the code that generates it
readable, this patch introduces a simple JSON writer. It emits JSON serially
into a buffer in memory.
The nice thing about this writer is its simplicity and low memory overhead.
Unlike the QMP JSON writer, this one does not need to spawn QObjects for every
element it wants to represent.
This is a prerequisite for the migration stream format description generator.

coverity: Model g_free() isn't necessarily free()
Memory allocated with GLib needs to be freed with GLib. Freeing it
with free() instead of g_free() is a common error. Harmless when
g_free() is a trivial wrapper around free(), which is commonly the
case. But model the difference anyway.
In a local scan, this flags four ALLOC_FREE_MISMATCH. Requires
--enable ALLOC_FREE_MISMATCH, because the checker is still preview.

coverity: Model GLib string allocation partially
Without a model, Coverity can't know that the result of g_strdup()
needs to be fed to g_free().
One way to get such a model is to scan GLib, build a derived model
file with cov-collect-models, and use that when scanning QEMU.
Unfortunately, the Coverity Scan service we use doesn't support that.
Thus, we're stuck with the other way: write a user model. Doing that
for all of GLib is hardly practical. I'm doing it for the "String
Utility Functions" we actually use that return dynamically allocated
strings.
In a local scan, this flags 20 additional RESOURCE_LEAKs. The ones I
checked look genuine.
It also loses a NULL_RETURNS about ppce500_init() using
qemu_find_file() without error checking. I don't understand why.

coverity: Improve model for GLib memory allocation
In current versions of GLib, g_new() may expand into g_malloc_n().
When it does, Coverity can't see the memory allocation, because we
don't model g_malloc_n(). Similarly for g_new0(), g_renew(),
g_try_new(), g_try_new0(), g_try_renew().
Model g_malloc_n(), g_malloc0_n(), g_realloc_n(). Model
g_try_malloc_n(), g_try_malloc0_n(), g_try_realloc_n() by adding
indeterminate out of memory conditions on top.
To avoid undue duplication, replace the existing models for g_malloc()
& friends by trivial wrappers around g_malloc_n() & friends.
In a local scan, this flags four additional RESOURCE_LEAKs and one
NULL_RETURNS.
The NULL_RETURNS is a false positive: Coverity can now see that
g_try_malloc(l1_sz * sizeof(uint64_t)) in
qcow2_check_metadata_overlap() may return NULL, but is too stupid to
recognize that a loop executing l1_sz times won't be entered then.
Three out of the four RESOURCE_LEAKs appear genuine. The false
positive is in ppce500_prep_device_tree(): the pointer dies, but a
pointer to a struct member escapes, and we get the pointer back for
freeing with container_of(). Too funky for Coverity.

We currently claim that for ARM the mmu_idx should simply be the current

should have separate indexes from non-secure EL0 and EL1 since their
VA->PA mappings may differ. We also will want an index for stage 2
translations when we properly support EL2.
Define and document all seven mmu index values that we require, and
pass the mmu index in the TB flags rather than exception level or
priv/user bit.

target-arm: check that LSB <= MSB in BFI instruction
The documentation states that if LSB > MSB in BFI instruction behaviour
is unpredictable. Currently QEMU crashes because of assertion failure in
this case:
tcg/tcg-op.h:2061: tcg_gen_deposit_i32: Assertion `len <= 32' failed.
While assertion failure may meet the "unpredictable" definition this
behaviour is undesirable because it allows an unprivileged guest program
to crash the emulator with the OS and other programs.
This patch addresses the issue by throwing illegal instruction exception
if LSB > MSB. Only ARM decoder is affected because Thumb decoder already
has this check in place.
To reproduce issue run the following program
int main(void) {
asm volatile (".long 0x07c00c12" :: );
return 0;
}
compiled with
gcc -marm -static badop_arm.c -o badop_arm

target-arm: Squash input denormals in FRECPS and FRSQRTS
The helper functions for FRECPS and FRSQRTS have special case
handling that includes checks for zero inputs, so squash input
denormals if necessary before those checks. This fixes incorrect
output when the FPCR DZ bit is set to enable squashing of input
denormals.

Fix FMULX not squashing denormalized inputs when FZ is set.
While FMULX returns a 2.0f float when two operators are infinity and
zero, those operators should be unpacked from raw inputs first. Inconsistent
cases would occur when operators are denormalized floats in flush-to-zero
mode. A wrong codepath will be entered and 2.0f will not be returned
without this patch.
Fix by checking whether inputs need to be flushed before running into
different codepaths.

target-arm: Add checks that cpreg raw accesses are handled
Add assertion checking when cpreg structures are registered that they
either forbid raw-access attempts or at least make an attempt at
handling them. Also add an assert in the raw-accessor-of-last-resort,
to avoid silently doing a read or write from offset zero, which is
actually AArch32 CPU register r0.

target-arm: Split NO_MIGRATE into ALIAS and NO_RAW
We currently mark ARM coprocessor/system register definitions with
the flag ARM_CP_NO_MIGRATE for two different reasons:
1) register is an alias on to state that's also visible via
some other register, and that other register is the one
responsible for migrating the state
2) register is not actually state at all (for instance the TLB
or cache maintenance operation "registers") and it makes no
sense to attempt to migrate it or otherwise access the raw state
This works fine for identifying which registers should be ignored
when performing migration, but we also use the same functions for
synchronizing system register state between QEMU and the kernel
when using KVM. In this case we don't want to try to sync state
into registers in category 2, but we do want to sync into registers
in category 1, because the kernel might have picked a different
one of the aliases as its choice for which one to expose for
migration. (In particular, on 32 bit hosts the kernel will
expose the state in the AArch32 version of the register, but
TCG's convention is to mark the AArch64 version as the version
to migrate, even if the CPU being emulated happens to be 32 bit,
so almost all system registers will hit this issue now that we've
added AArch64 system emulation.)
Fix this by splitting the NO_MIGRATE flag in two (ALIAS and NO_RAW)
corresponding to the two different reasons we might not want to
migrate a register. When setting up the TCG list of registers to
migrate we honour both flags; when populating the list from KVM,
only ignore registers which are NO_RAW.

vfio-pci: Fix missing unparent of dynamically allocated MemoryRegion
Commit d8d95814609e added explicit object_unparent() calls for
dynamically allocated MemoryRegions. The VFIOMSIXInfo structure also
contains such a MemoryRegion, covering the mmap'd region of a PCI BAR
above the MSI-X table. This structure is freed as part of the class
exit function and therefore also needs an explicit object_unparent().
Failing to do this results in random segfaults due to fields within
the structure, often the class pointer, being reclaimed and corrupted
by the time object_finalize_child_property() is called for the object.

target-s390x: fix and optimize slb* and slbg* computation of carry/borrow flag
This patch fixes the bug with borrow_in being set incorrectly, but it
also simplifies the logic to be much more plain, improving speed. It
fixes both the 32-bit SLB* and 64-bit SLBG*.
The SLBG* change has been well-tested. I haven't tested the SLB* change
explicitly, but the code was copy-pasted from the tested code.
The error of these functions' current implementations would not likely
be triggered by compiler-generated code, since the only error was in the
state of the carry/borrow flag. Compilers rarely generate an
instruction sequence such as carry-set -> carry-set-and-use ->
carry-use.
(With Paolo's fix and mine, there are still a couple of failures from
GMP's testsuite, but they are almost surely due to incorrect code
generation from gcc 4.9. But since this gcc is running under qemu, it
might be qemu bugs. I intend to investigate this.)

s390x/kvm: unknown DIAGNOSE code should give a specification exception
As described in CP programming services an unimplemented DIAGNOSE
function should return a specification exception. Today we give the
guest an operation exception.
As both exception types are suppressing and Linux as a guest does not
care about the type of program check in its exception table handler
as long as both types have the same kind of error handling (nullifying,
terminating, suppressing etc.) this was unnoticed.

Asynchronous callbacks provided by call_rcu are particularly important

In addition, the current RCU implementation is not particularly friendly

more important.

rcu: add rcu library
This includes a (mangled) copy of the liburcu code. The main changes
are: 1) removing dependencies on many other header files in liburcu; 2)
removing for simplicity the tentative busy waiting in synchronize_rcu,
which has limited performance effects; 3) replacing futexes in
synchronize_rcu with QemuEvents for Win32 portability. The API is
the same as liburcu, so it should be possible in the future to require
liburcu on POSIX systems for example and use our copy only on Windows.
Among the various versions available I chose urcu-mb, which is the
least invasive implementation even though it does not have the
fastest rcu_read_{lock,unlock} implementation. The urcu flavor can
be changed later, after benchmarking.

are under the BSD license. Clarify this in the comments at the

the assumed licensing for future contributions, so we don't need

Revert the parts of commits b645bb4885 and 5a6932d51d which are still
in the codebase and under a SoftFloat-2b license.
Reimplement support for architectures where the most significant bit
in the mantissa is 1 for a signaling NaN rather than a quiet NaN,
by adding handling for SNAN_BIT_IS_ONE being set to the functions
which test values for NaN-ness.
This includes restoring the bugfixes lost in the reversion where
some of the float*_is_quiet_nan() functions were returning true
for both signaling and quiet NaNs.

Commit 7572150 adopted QERR_DEVICE_NOT_ACTIVE for the purpose,

Produces "No spice device has been activated", which is awkward.
We've since abandoned our quest for "rich" error objects. Time to

linux-user: Fix broken m68k signal handling on 64 bit hosts
The m68k signal frame setup code which writes the signal return
trampoline code to the stack was assuming that a 'long' was 32 bits;
on 64 bit systems this meant we would end up writing the 32 bit
(2 insn) trampoline sequence to retaddr+4,retaddr+6 instead of
the intended retaddr+0,retaddr+2, resulting in a guest crash when
it tried to execute the invalid zero-bytes at retaddr+0.
Fix by using uint32_t instead; also use uint16_t rather than short
for consistency. This fixes bug LP:1404690.

linux-user: Fix ioctl cmd type mismatch on 64-bit targets
linux-user passes the cmd argument of the ioctl syscall as a signed long,
but compares it to an unsigned int when iterating through the ioctl_entries
list. When the cmd is a large value like 0x80047476 (TARGET_TIOCSWINSZ on
mips64) it gets sign-extended to 0xffffffff80047476, causing the comparison
to fail and resulting in lots of spurious "Unsupported ioctl" errors.
Changing the target_cmd field in the ioctl_entries list to a signed int
causes those values to be sign-extended as well during the comparison.

linux-user/signal.c: Remove unnecessary wrapper copy_siginfo_to_user
The function copy_siginfo_to_user() just calls tswap_siginfo(), so
call the latter function directly and delete the wrapper function.
The wrapper is actually misleading since it implies that the
semantics are like the kernel function with the same name which
copies the data to a guest user-space address. In fact tswap_siginfo()
just does data-structure conversion between two structures whose
addresses are host addresses (the copy to userspace is handled
in QEMU by the lock_user/unlock_user calls).
This also fixes clang complaints about the wrapper being unused
in some configs.

linux-user/alpha: Add define for NR_shmat to enable shmat syscall
For historical reasons, the define for the shmat() syscall on Alpha is
NR_osf_shmat; however it has the same semantics as this syscall does
on all other architectures, so define TARGET_NR_shmat as well so that
QEMU's code for the syscall is enabled.
This patch brings our behaviour on the LTP shmat tests into line
with that for ARM (still not a perfect pass rate but not "this syscall
is completely broken" as we had before).
(Problem detected via a clang warning that the do_shmat() function
was unused on Alpha.)

linux-user/signal.c: Remove current_exec_domain_sig()
Remove the function current_exec_domain_sig(), which always returns
its argument. This was intended as a stub for supporting the kernel's
exec_domain handling, but:
* we don't have any of the other code for execution domains
* in the kernel this handling is architecture-specific, not generic
* we only call this function in the x86, ppc and sh4 signal code paths,
and the PPC one is wrong anyway because the PPC kernel doesn't
have this signal-remapping code
So it's best to simply delete the function; any future attempt to
implement exec domains will be better served by adding the correct
code from scratch based on the kernel sources at that time.
This change also fixes some clang warnings about the function being
defined but not used for some target architectures.

target-tricore: split up suov32 into suov32_pos and suov32_neg
suov checks unsigned for an overflow and an underflow, after some arithmetic
operations and saturates the result to either max_uint32 or 0. So far we
handled this by expanding to the next bigger data type and compare whether
the result is > max_uint32 or < 0.
However this approach can fail for an 32 bit multiplication, if both operands of
the multiplication are 0x80000000. This sets the sign bit of the 64 bit integer
and would result in a false saturation to 0.
Since unsigned operations, e.g add, sub, mul always result in either a positive
or negative overflow, we split the functions for suov32 up into two functions
(suov32_pos, suov32_neg) for each case.

pci: Split pcie_host_mmcfg_map()
The mmcfg space is a memory region that allows access to PCI config space
in the PCIe world. To maintain abstraction layers, I would like to expose
the mmcfg space as a sysbus mmio region rather than have it mapped straight
into the system's memory address space though.
So this patch splits the initialization of the mmcfg space from the actual
mapping, allowing us to only have an mmfg memory region without the map.

ich9: add disable_s3, disable_s4, s4_val properties
PIIX4 has disable_s3 and disable_s4 properties to enable or disable PM
functions. Add such properties to the ICH9 chipset as well for the Q35
machine type.
S3 / S4 are not guaranteed to always work (needs work in the guest as
well as QEMU for things to work properly), and disabling advertising of
these features ensures guests don't go into zombie state if something
isn't working right.
The defaults are kept the same as in PIIX4: both S3 and S4 are enabled
by default.
These can be disabled via the cmdline:
... -global ICH9-LPC.disable_s3=1 -global ICH9-LPC.disable_s4=1
Note: some guests can fake hibernation by writing a hibernate image and
doing a shutdown instead of S4 if S4 isn't available; there's nothing we
can do guests to stop doing this, and this patch can't affect that
functionality.

qemu-timer.c: Trim list of included headers
qemu-timer.c was including a lot more headers than it needed to,
presumably for historical reasons. In particular, it included
ui/console.h; this now tries to pull in <pixman.h>, which will
cause a compilation failure in --disable-tools --disable-system
configurations when running "make check" (which builds qemu-timer.c,
even though the linux-user binaries themselves don't need it).
Fix this build failure by trimming down the set of included
headers severely -- we only really need main-loop.h and timer.h.

kvm_stat: Add RESET support for perf event ioctl
While running kvm_stat using tracepoint on ARM64 hardware (e.g. "kvm_stat
-1 -t"), the initial values of some kvm_userspace_exit counters were found
to be very suspecious. For instance the tracing tool showed that S390_TSCH
was called many times on ARM64 machine, which apparently was wrong.
This patch adds RESET ioctl support for perf monitoring. Before calling
ioctl to enable a perf event, this patch resets the counter first. With
this patch, the init counter values become correct on ARM64 hardware.
Example:
==== before patch ====
kvm_userspace_exit(S390_SIEIC) 1426 0
kvm_userspace_exit(S390_TSCH) 339 0
==== after patch ====
kvm_userspace_exit(S390_SIEIC) 0 0
kvm_userspace_exit(S390_TSCH) 0 0

Right now you only get to apic_init_reset if you have an APIC
(do_cpu_init is reached only if CPU_INTERRUPT_INIT is set and
that only happens in hw/intc/apic.c). However, this is wrong
because for example a port 92 or keyboard controller reset is
really an INIT, and that can happen also with no APIC. So
keep the check and fix the error that Coverity reported.

qemu-timer: introduce timer_deinit
In some cases, a timer was set to NULL so that we could check if it is
initialized. Use the timer_list field instead, and add a timer_deinit
function that NULLs it.
It then makes sense that timer_del be a no-op (instead of a crasher) on
such a de-initialized timer. It avoids the need to poke at the timerlist
field to check if the timers are initialized.

target-i386: make xmm_regs 512-bit wide
Right now, the AVX512 registers are split in many different fields:
xmm_regs for the low 128 bits of the first 16 registers, ymmh_regs
for the next 128 bits of the same first 16 registers, zmmh_regs
for the next 256 bits of the same first 16 registers, and finally
hi16_zmm_regs for the full 512 bits of the second 16 bit registers.
This makes it simple to move data in and out of the xsave region,
but would be a nightmare for a hypothetical TCG implementation and
leads to a proliferation of [XYZ]MM_[BWLSQD] macros. Instead,
this patch marshals data manually from the xsave region to a single
32x512-bit array, simplifying the macro jungle and clarifying which
bits are in which vmstate subsection.
The migration format is unaffected.

While changing this, change the macros to accept the index of the first

of elements (which is always CPU_NB_REGS).

block: vhdx - force FileOffsetMB field to '0' for certain block states
The v1.0.0 spec calls out PAYLOAD_BLOCK_ZERO FileOffsetMB field as being
'reserved'. In practice, this means that Hyper-V will fail to read a
disk image with PAYLOAD_BLOCK_ZERO block states with a FileOffsetMB
value other than 0.
The other states that indicate a block that is not there
(PAYLOAD_BLOCK_UNDEFINED, PAYLOAD_BLOCK_NOT_PRESENT,
PAYLOAD_BLOCK_UNMAPPED) have multiple options for what FileOffsetMB may
be set to, and '0' is explicitly called out as an option.
For all the above states, we will also just set the FileOffsetMB value
to 0.

block: update string sizes for filename,backing_file,exact_filename
The string field entries 'filename', 'backing_file', and
'exact_filename' in the BlockDriverState struct are defined as 1024
bytes.
However, many places that use these values accept a maximum of PATH_MAX
bytes, so we have a mixture of 1024 byte and PATH_MAX byte allocations.
This patch makes the BlockDriverStruct field string sizes match usage.
This patch also does a few fixes related to the size that needs to
happen now:
* the block qapi driver is updated to use PATH_MAX bytes
* the qcow and qcow2 drivers have an additional safety check
* the block vvfat driver is updated to use PATH_MAX bytes
for the size of backing_file, for systems where PATH_MAX is < 1024
bytes.
* qemu-img uses PATH_MAX rather than 1024. These instances were not
changed to be dynamically allocated, however, as the extra
temporary 3K in stack usage for qemu-img does not seem worrisome.

We technically only need 1 byte, as we are just checking for NULL, but
since backing_filename[] is populated by bdrv_get_backing_filename(), a
string size of 1 will always only return '\0';

hw/input/hid.c Fix capslock hid code
When ever USB keyboard is used, e.g. '-usbdevice keyboard' pressing
caps lock key send 0x32 hid code, which is treated as backslash.
Instead it should be 0x39 code. This affects sending uppercase keys,
as they typed whith caps lock active.
While on x86 this can be workarounded by using ps/2 protocol. On
Power it is crusial as we don't have anything else than USB.

* Each vnc server returns a list of server sockets. Followup patch
will use that to also report websockets. In case we add support for
multiple server sockets server sockets (to better support ipv4+ipv6

vnc: track & limit connections
Also track the number of connections in "connecting" and "shared" state
(in addition to the "exclusive" state). Apply a configurable limit to
these connections.
The logic to apply the limit to connections in "shared" state is pretty
simple: When the limit is reached no new connections are allowed.
The logic to apply the limit to connections in "connecting" state (this
is the state you are in *before* successful authentication) is
slightly different: A new connect kicks out the oldest client which is
still in "connecting" state. This avoids a easy DoS by unauthenticated
users by simply opening connections until the limit is reached.

sb16: fix interrupt acknowledgement
SoundBlaster 16 emulation is very broken and consumes a lot of CPU, but a
small fix was suggested offlist and it is enough to fix some games. I
got Epic Pinball to work with the "SoundBlaster Clone" option.
The processing of the interrupt register is wrong due to two missing
"not"s. This causes the interrupt flag to remain set even after the
Acknowledge ports have been read (0x0e and 0x0f).
The line was introduced by commit 85571bc (audio merge (malc), 2004-11-07),
but the code might have been broken before because I did not look closely
at the huge patches from 10 years ago.

cpu_ldst.h: Don't define helpers if MMU_MODE*_SUFFIX not defined
Not all targets define a full set of suffix strings for the
NB_MMU_MODES that they have. In this situation, don't define any
helper functions for that mode, rather than defining helper functions
with no suffix at all. The MMU mode is still functional; it is merely
not directly accessible via cpu_ld*_MODE from target helper functions.
Also add an "NB_MMU_MODES >= 2" check to the definition of the mode 1
helpers -- some targets only define one MMU mode.

cpu_ldst.h: Use inline functions for usermode cpu_ld/st accessors
Use inline functions rather than macros for cpu_ld/st accessors
for the *-user configurations, as we already do for softmmu.
This has a two advantages:
* we can actually typecheck our arguments
* we don't need to leak the _raw macros everywhere
Since the _kernel functions were only used by target-i386/seg_helper.c,
put the definitions for them in that file too. (It already has the
similar template include code to define them for the softmmu case,
so it makes sense to have it deal with defining them for user-only.)

monitor.c: Use ld*_p() instead of ld*_raw()
The monitor code for doing a memory_dump() was using ld*_raw() to do
target-CPU accesses out of a local buf[] array. The correct functions
for this purpose are ld*_p(), which take a host pointer, rather than
ld*_raw(), which take an integer representing a guest address and
are somewhat meaningless in softmmu configurations. Nobody noticed
because for softmmu the _raw functions are the same as ldl_p but
with some extra casts thrown in. Switch to using the correct functions
instead.

exec.c: Drop TARGET_HAS_ICE define and checks
The TARGET_HAS_ICE #define is intended to indicate whether a target-*
guest CPU implementation supports the breakpoint handling. However,
all our guest CPUs have that support (the only two which do not
define TARGET_HAS_ICE are unicore32 and openrisc, and in both those
cases the bp support is present and the lack of the #define is just
a bug). So remove the #define entirely: all new guest CPU support
should include breakpoint handling as part of the basic implementation.

scripts/qapi-types.py: Add dummy member to empty structs
Make sure that all generated C structs have at least one field; this
avoids potential issues with attempting to malloc space for
zero-length structs in C (g_malloc(sizeof struct) would return NULL).
It also avoids an incompatibility with C++ (where an empty struct is
size 1); that isn't important to us now but might be in future.
Generated empty structures look like this:
struct Abort
{
char qapi_dummy_field_for_empty_struct;
};
This silences clang warnings like:
./qapi-types.h:3752:1: warning: empty struct has size 0 in C, size 1 in C++ [-Wextern-c-compat]

Xen: Use the ioreq-server API when available
The ioreq-server API added to Xen 4.5 offers better security than
the existing Xen/QEMU interface because the shared pages that are
used to pass emulation request/results back and forth are removed
from the guest's memory space before any requests are serviced.
This prevents the guest from mapping these pages (they are in a
well known location) and attempting to attack QEMU by synthesizing
its own request structures. Hence, this patch modifies configure
to detect whether the API is available, and adds the necessary
code to use the API if it is.

fw_cfg: fix endianness in fw_cfg_data_mem_read() / _write()
target-arm: crypto: fix BE host support
Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
commit 36b62ae6a58f9a588fd33be9386e18a2b90103f5
Author: Laszlo Ersek <lersek@redhat.com>
Date: Fri Jan 16 11:54:30 2015 +0000
fw_cfg: fix endianness in fw_cfg_data_mem_read() / _write()
(1) Let's contemplate what device endianness means, for a memory mapped
device register (independently of QEMU -- that is, on physical hardware).
It determines the byte order that the device will put on the data bus when
the device is producing a *numerical value* for the CPU. This byte order
may differ from the CPU's own byte order, therefore when software wants to
consume the *numerical value*, it may have to swap the byte order first.
For example, suppose we have a device that exposes in a 2-byte register
the number of sheep we have to count before falling asleep. If the value
is decimal 37 (0x0025), then a big endian register will produce [0x00,
0x25], while a little endian register will produce [0x25, 0x00].
If the device register is big endian, but the CPU is little endian, the
numerical value will read as 0x2500 (decimal 9472), which software has to
byte swap before use.
However... if we ask the device about who stole our herd of sheep, and it
answers "XY", then the byte representation coming out of the register must
be [0x58, 0x59], regardless of the device register's endianness for
numeric values. And, software needs to copy these bytes into a string
field regardless of the CPU's own endianness.
(2) QEMU's device register accessor functions work with *numerical values*
exclusively, not strings:
The emulated register's read accessor function returns the numerical value
(eg. 37 decimal, 0x0025) as a *host-encoded* uint64_t. QEMU translates
this value for the guest to the endianness of the emulated device register
(which is recorded in MemoryRegionOps.endianness). Then guest code must
translate the numerical value from device register to guest CPU
endianness, before including it in any computation (see (1)).
(3) However, the data register of the fw_cfg device shall transfer strings
*only* -- that is, opaque blobs. Interpretation of any given blob is
subject to further agreement -- it can be an integer in an independently
determined byte order, or a genuine string, or an array of structs of
integers (in some byte order) and fixed size strings, and so on.
Because register emulation in QEMU is integer-preserving, not
string-preserving (see (2)), we have to jump through a few hoops.
(3a) We defined the memory mapped fw_cfg data register as
DEVICE_BIG_ENDIAN.
The particular choice is not really relevant -- we picked BE only for
consistency with the control register, which *does* transfer integers --
but our choice affects how we must host-encode values from fw_cfg strings.
(3b) Since we want the fw_cfg string "XY" to appear as the [0x58, 0x59]
array on the data register, *and* we picked DEVICE_BIG_ENDIAN, we must
compose the host (== C language) value 0x5859 in the read accessor
function.
(3c) When the guest performs the read access, the immediate uint16_t value
will be 0x5958 (in LE guests) and 0x5859 (in BE guests). However, the
uint16_t value does not matter. The only thing that matters is the byte
pattern [0x58, 0x59], which the guest code must copy into the target
string *without* any byte-swapping.
(4) Now I get to explain where I screwed up. :(
When we decided for big endian *integer* representation in the MMIO data
register -- see (3a) --, I mindlessly added an indiscriminate
byte-swizzling step to the (little endian) guest firmware.
This was a grave error -- it violates (3c) --, but I didn't realize it. I
only saw that the code I otherwise intended for fw_cfg_data_mem_read():
value = 0;
for (i = 0; i < size; ++i) {
value = (value << 8) | fw_cfg_read(s);
}
didn't produce the expected result in the guest.
In true facepalm style, instead of blaming my guest code (which violated
(3c)), I blamed my host code (which was correct). Ultimately, I coded
ldX_he_p() into fw_cfg_data_mem_read(), because that happened to work.
Obviously (...in retrospect) that was wrong. Only because my host happened
to be LE, ldX_he_p() composed the (otherwise incorrect) host value 0x5958
from the fw_cfg string "XY". And that happened to compensate for the bogus
indiscriminate byte-swizzling in my guest code.
Clearly the current code leaks the host endianness through to the guest,
which is wrong. Any device should work the same regardless of host
endianness.
The solution is to compose the host-endian representation (2) of the big
endian interpretation (3a, 3b) of the fw_cfg string, and to drop the wrong
byte-swizzling in the guest (3c).
Brown paper bag time for me.

target-arm: crypto: fix BE host support
The crypto emulation code in target-arm/crypto_helper.c never worked
correctly on big endian hosts, due to the fact that it uses a union
of array types to convert between the native VFP register size (64
bits) and the types used in the algorithms (bytes and 32 bit words)
We cannot just swab between LE and BE when reading and writing the
registers, as the SHA code performs word additions, so instead, add
array accessors for the CRYPTO_STATE type whose LE and BE specific
implementations ensure that the correct array elements are referenced.

Handle bi-directional communication for fd migration
libvirt prefers opening the TCP connection itself, for two reasons.
First, connection failed errors can be detected easier, without having
to parse qemu's error output.
Second, libvirt might be asked to secure the transfer by tunnelling the
communication through an TLS layer.
Therefore, libvirt opens the TCP connection itself and passes an FD to qemu
using QMP and a POSIX-specific mechanism.
Hence, in order to make the reverse-path work in such cases, qemu needs to
distinguish if the transmitted FD is a socket (reverse-path available)
or not (reverse-path might not be available) and use the corresponding
abstraction.

QEMUSizedBuffer: only free qsb that qemu_bufopen allocated
Only free qsb that qemu_bufopen allocated, and also allow
qemu_bufopen accept qsb as input for write operation. It
will make the API more logical:
1.If you create the QEMUSizedBuffer yourself, you need to
free it by using qsb_free() but not depends on other API
like qemu_fclose.
2.allow qemu_bufopen() accept QEMUSizedBuffer as input for
write operation, otherwise, it will be a little strange
for this API won't accept the second parameter.
This brings API change, since there are only 3
users of this API currently, this change only impact the
first one which will be fixed in patch 2 of this patchset,
so I think it is safe to do this change.

warnings on clang 3.4 or later. This means we don't need to mark it
'inline', which is what we were previously using to suppress the warning
(a trick which only works with gcc, not clang).

superio_ioport_readb can read the 256th element of the array.
Coverity reports an out-of-bounds write in superio_ioport_writeb,

ide: Implement VPD response for ATAPI
SCSI devices have multiple kinds of queries they need to respond
to, as defined in the "cmd inquiry" section in MMC-6 and SPC-3.
Relevent sections:
MMC-6 revision 2g:
Non-VPD response data and pointer to SPC-3;
Section 6.8 "Inquiry Command"
SPC-3 revision 23:
Inquiry command and error handling:
Section 6.4 "INQUIRY command"
VPD data pages format:
Section 7.6 "Vital product data parameters"
We implement these Vital Product Data queries for SCSI, but not for
ATAPI through IDE. The result is that if you are looking for the WWN
identifier via tools such as sg3_utils, you will be unable to query
our CD/DVD rom device to obtain it.
This patch adds the minimum number of mandatory responses as defined
by SPC-3, which include the "supported pages" response (page 0x00)
and the "Device Identification" response (page 0x83). It also correctly
responds when it receives a request for an illegal page to improve
error output from related tools.
The Device ID page contains an arbitrary list of identification
strings of various formats; the ID strings included in this patch
were chosen to mimic those provided by the libata driver when
emulating this SCSI query (model, serial, and wwn when present.)
Example:
# libata emulated response
[root@localhost ~]# sg_inq --id /dev/sda
VPD INQUIRY: Device Identification page

block: Split BLOCK_OP_TYPE_COMMIT to BLOCK_OP_TYPE_COMMIT_{SOURCE, TARGET}
Like BLOCK_OP_TYPE_BACKUP_SOURCE and BLOCK_OP_TYPE_BACKUP_TARGET,
block-commit involves two asymmetric devices.
This change is not user-visible (yet), because commit only works with
device names.
But once we enable backing reference in blockdev-add, or specifying
node-name in block-commit command, we don't want the user to start two
commit jobs on the same backing chain, which will corrupt things because
of the final bdrv_swap.
Before we have per category blockers, splitting this type is still
better.
[Resolved virtio-blk dataplane conflict by replacing
BLOCK_OP_TYPE_COMMIT with both BLOCK_OP_TYPE_COMMIT_{SOURCE, TARGET}.
They are safe since the block job runs in the same AioContext as the
dataplane IOThread.

coroutine: try harder not to delete coroutines
Placing coroutines on the global pool should be preferrable, because it
can help all threads. But if the global pool is full, we can still
try to save some allocations by stashing completed coroutines on the
local pool. This is quite cheap too, because it does not require
atomic operations, and provides a gain of 15% in the best case.

coroutine: rewrite pool to avoid mutex
This patch removes the mutex by using fancy lock-free manipulation of
the pool. Lock-free stacks and queues are not hard, but they can suffer
from the ABA problem so they are better avoided unless you have some
deferred reclamation scheme like RCU. Otherwise you have to stick
with adding to a list, and emptying it completely. This is what this
patch does, by coupling a lock-free global list of available coroutines
with per-CPU lists that are actually used on coroutine creation.
Whenever the destruction pool is big enough, the next thread that runs
out of coroutines will steal the whole destruction pool. This is positive
in two ways:
1) the allocation does not have to do any atomic operation in the fast
path, it's entirely using thread-local storage. Once every POOL_BATCH_SIZE
allocations it will do a single atomic_xchg. Release does an atomic_cmpxchg
loop, that hopefully doesn't cause any starvation, and an atomic_inc.
A later patch will also remove atomic operations from the release path,
and try to avoid the atomic_xchg altogether---succeeding in doing so if
all devices either use ioeventfd or are not submitting requests actively.
2) in theory this should be completely adaptive. The number of coroutines
around should be a little more than POOL_BATCH_SIZE * number of allocating
threads; so this also empties qemu_coroutine_adjust_pool_size. (The previous
pool size was POOL_BATCH_SIZE * number of block backends, so it was a bit
more generous. But if you actually have many high-iodepth disks, it's better
to put them in different iothreads, which will also use separate thread
pools and aio=native file descriptors).
This speeds up perf/cost (in tests/test-coroutine) by a factor of ~1.33.
No matter if we end with some kind of coroutine bypass scheme or not,
it cannot hurt to optimize hot code.

qemu-thread: add per-thread atexit functions
Destructors are the main additional feature of pthread TLS compared
to __thread. If we were using C++ (hint, hint!) we could have used
thread-local objects with a destructor. Since we are not, instead,
we add a simple Notifier-based API.
Note that the notifier must be per-thread as well. We can add a
global list as well later, perhaps.
The Win32 implementation has some complications because a) detached
threads used not to have a QemuThreadData; b) the main thread does
not go through win32_start_routine, so we have to use atexit too.

coroutine-ucontext: use __thread
ELF thread local storage is about 10% faster on tests/test-coroutine's
perf/cost test. The timing on my machine is 190ns per iteration with
pthread TLS, 170 with ELF TLS.
Based on a patch by Kevin Wolf and Peter Lieven, but redone to follow
the model of coroutine-win32.c (including the important "noinline"
attribute!).
Platforms without thread-local storage (OpenBSD probably?) will need
a new-enough GCC for this to compile, in order to use the same emutls
support that Windows already relies on.

xen-pt: Fix PCI devices re-attach failed
Use the 'xl pci-attach $DomU $BDF' command to attach more than
one PCI devices to the guest, then detach the devices with
'xl pci-detach $DomU $BDF', after that, re-attach these PCI
devices again, an error message will be reported like following:
libxl: error: libxl_qmp.c:287:qmp_handle_error_response: receive
an error message from QMP server: Duplicate ID 'pci-pt-03_10.1'
for device.
If using the 'address_space_memory' as the parameter of
'memory_listener_register', 'xen_pt_region_del' will not be called
if the memory region's name is not 'xen-pci-pt-*' when the devices
is detached. This will cause the device's related QemuOpts object
not be released properly.
Using the device's address space can avoid such issue, because the
calling count of 'xen_pt_region_add' when attaching and the calling
count of 'xen_pt_region_del' when detaching is the same, so all the
memory region ref and unref by the 'xen_pt_region_add' and
'xen_pt_region_del' can be released properly.

Because of this, the QGuestAllocator has been removed from is function to wrap

migration/block: fix pending() return value
Because of wrong return value of .save_live_pending() in
migration/block.c, migration finishes before the whole disk is
transferred. Such situation occurs when the migration process is fast
enough, for example when source and dest are on the same host.
If in the bulk phase we return something < max_size, we will skip
transferring the tail of the device. Currently we have "set pending to
BLOCK_SIZE if it is zero" for bulk phase, but there no guarantee, that
it will be < max_size.
True approach is to return, for example, max_size+1 when we are in the
bulk phase.

block: fix spoiling all dirty bitmaps by mirror and migration
Mirror and migration use dirty bitmaps for their purposes, and since
commit [block: per caller dirty bitmap] they use their own bitmaps, not
the global one. But they use old functions bdrv_set_dirty and
bdrv_reset_dirty, which change all dirty bitmaps.
Named dirty bitmaps series by Fam and Snow are affected: mirroring and
migration will spoil all (not related to this mirroring or migration)
named dirty bitmaps.
This patch fixes this by adding bdrv_set_dirty_bitmap and
bdrv_reset_dirty_bitmap, which change concrete bitmap. Also, to prevent
such mistakes in future, old functions bdrv_(set,reset)_dirty are made
static, for internal block usage.

When using a relative backing file name, qemu needs to know the

checkpatch: Brace handling on multi-line condition
CODING_STYLE states the following about braces around blocks:
> The opening brace is on the line that contains the control flow
> statement that introduces the new block; [...]
This is obviously impossible with multi-line conditions. Therefore,
CODING_STYLE does not make any clear statement about where to put the
opening brace after a multi-line condition.
There is a reason to prefer to place the opening brace on an own line
after such a condition while still placing it on the same line as the
"control flow statement" if possible; that reason is that the last line
of a multi-line condition is indented, in the case of "if", it is often
indented by four spaces, just as much as the first statement in the
block will be indented. This is hard to read as there is no clearly
visible distinction between condition and block. Placing the opening
brace on a separate line solves this issue.
Also, there are cases where placing the opening brace on a separate line
is the only viable option; if the previous line had nearly 80 characters
and splitting it is not desirable, the opening brace is naturally placed
on an own line.
This patch fixes checkpatch.pl to not complain about braces on own lines
if the condition introducing the block spanned more than one line, or if
the previous line had 79 or 80 characters.
Furthermore, the warning about not having braces around a block is fixed
to mind braces not being on the last line of the condition.

net: remove all cleanup methods from NIC NetClientInfos
All NICs have a cleanup function that, in most cases, zeroes the pointer
to the NICState. In some cases, it frees data belonging to the NIC.
However, this function is never called except when exiting from QEMU.
It is not necessary to NULL pointers and free data here; the right place
to do that would be in the device's unrealize function, after calling
qemu_del_nic. Zeroing the NIC multiple times is also wrong for multiqueue
devices.
This cleanup function gets in the way of making the NetClientStates for
the NIC hold an object_ref reference to the object, so get rid of it.

kvm: extend kvm_irqchip_add_msi_route to work on s390
on s390 MSI-X irqs are presented as thin or adapter interrupts
for this we have to reorganize the routing entry to contain
valid information for the adapter interrupt code on s390.
To minimize impact on existing code we introduce an architecture
function to fixup the routing entry.

s390: implement pci instructions
This patch implements the s390 pci instructions in qemu. It allows
to access and drive pci devices attached to the s390 pci bus.
Because of platform constrains devices using IO BARs are not
supported. Also a device has to support MSI/MSI-X to run on s390.

s390x/kvm: avoid syscalls by syncing registers with kvm_run
We can avoid loads of syscalls when dropping to user space by storing the values
of more registers directly within kvm_run.
Support is added for:

guest breaking-event register, program parameter

vl: Don't silently change topology when all -smp options were set
QEMU tries to change the "threads" option even if it was explicitly set
in the command-line, and it shouldn't do that.
The right thing to do when all options (cpus, sockets, cores, threds)
are explicitly set is to sanity check them and abort in case they don't
make sense (i.e. when sockets*cores*threads < cpus).

vfio-pci: Fix interrupt disabling
When disabling MSI/X interrupts the disable functions will leave the
device in INTx mode (when available). This matches how hardware
operates, INTx is enabled unless MSI/X is enabled (DisINTx is handled
separately). Therefore when we really want to disable all interrupts,
such as when removing the device, and we start with the device in
MSI/X mode, we need to pass through INTx on our way to being
completely quiesced.
In well behaved situations, the guest driver will have shutdown the
device and it will start vfio_exitfn() in INTx mode, producing the
desired result. If hot-unplug causes the guest to crash, we may get
the device in MSI/X state, which will leave QEMU with a bogus handler
installed.
Fix this by re-ordering our disable routine so that it should always
finish in VFIO_INT_NONE state, which is what all callers expect.

vfio-pci: Fix BAR size overflow
We use an unsigned int when working with the PCI BAR size, which can
obviously overflow if the BAR is 4GB or larger. This needs to change
to a fixed length uint64_t. A similar issue is possible, though even
more unlikely, when mapping the region above an MSI-X table. The
start of the MSI-X vector table must be below 4GB, but the end, and
therefore the start of the next mapping region, could still land at
4GB.

Some ppc machines create a default usb controller based on a 'machine condition'.
Until now the logic was: create the usb controller if:
- the usb option was supplied in cli and value is true or
- the usb option was absent and both set_defaults and the machine
condition were true.
Modified the logic to:
Create the usb controller if:
- the machine condition is true and defaults are enabled or
- the usb option is supplied and true.
The main for this is to simplify the usb_enabled method.

acpi-build: make ROMs RAM blocks resizeable
Use resizeable ram API so we can painlessly extend ROMs in the
future. Note: migration is not affected, as we are
not actually changing the used length for RAM, which
is the part that's migrated.
Use this in acpi: reserve x16 more RAM space.

memory: API to allocate resizeable RAM MR
Add API to allocate resizeable RAM MR.
This looks just like regular RAM generally, but
has a special property that only a portion of it
(used_length) is actually used, and migrated.
This used_length size can change across reboots.
Follow up patches will change used_length for such blocks at migration,
making it easier to extend devices using such RAM (notably ACPI,
but in the future thinkably other ROMs) without breaking migration
compatibility or wasting ROM (guest) memory.
Device is notified on resize, so it can adjust if necessary.
Note: nothing prevents making all RAM resizeable in this way.
However, reviewers felt that only enabling this selectively will
make some class of errors easier to detect.

PPC: Fix crash on spapr_tce_table_finalize()
spapr_tce_table_finalize() can SEGV if the object was not previously
realized. In particular this can be triggered by running
qemu-system-ppc -device spapr-tce-table,?
The basic problem is that we have mismatched initialization versus
finalization: spapr_tce_table_finalize() is attempting to undo things that
are done in spapr_tce_table_realize(), not an instance_init function.
Therefore, replace spapr_tce_table_finalize() with
spapr_tce_table_unrealize().

target-ppc: explicitly save page table headers in big endian
Currently, when the page tables are saved, the kvm_get_htab_header structs
and the ptes are assumed being big endian and dumped as a indistinct blob
in the statefile. This is no longer true when the host is little endian
and this breaks restoration.
This patch unfolds the kvmppc_save_htab routine to write explicitly the

target-ppc: Fix Floating Point Move Instructions That Set CR1
The Floating Point Move instructions (fmr., fabs., fnabs., fneg.,
and fcpsgn.) incorrectly copy FPSCR[FPCC] instead of [FX,FEX,VX,OX].
Furthermore, the current code does this via a call to gen_compute_fprf,
which is awkward since these instructions do not actually set FPRF.
Change the code to use the gen_set_cr1_from_fpscr utility.

target-ppc: VXSQRT Should Not Be Set for NaNs
The Power ISA square root instructions (fsqrt[s], frsqrte[s]) must
set the FPSCR[VXSQRT] flag when operating on a negative value.
However, NaNs have no sign and therefore this flag should not
be set when operating on one.
Change the order of the checks in the helper code. Move the
SNaN-to-QNaN macro to the top of the file so that it can be
re-used.

target-ppc: Load/Store Vector Element Storage Alignment
The Load Vector Element Indexed and Store Vector Element Indexed
instructions compute an effective address in the usual manner.
However, they truncate that address to the natural boundary.
For example, the lvewx instruction will ignore the least significant
two bits of the address and thus load the aligned word of storage.
Fix the generators for these instruction to properly perform this
truncation.

PPC: e500 pci host: Add support for ATMUs
The e500 PCI controller has configurable windows that allow a guest OS
to selectively map parts of the PCI bus space to CPU address space and
to selectively map parts of the CPU address space for DMA requests into
PCI visible address ranges.
So far, we've simply assumed that this mapping is 1:1 and ignored it.
However, the PCICSRBAR (CCSR mapped in PCI bus space) always has to live
inside the first 32bits of address space. This means if we always treat
all mappings as 1:1, this map will collide with our RAM map from the CPU's
point of view.
So this patch adds proper ATMU support which allows us to keep the PCICSRBAR
below 32bits local to the PCI bus and have another, different window to PCI
BARs at the upper end of address space. We leverage this on e500plat though,
mpc8544ds stays virtually 1:1 like it was before, but now also goes via ATMU.
With this patch, I can run guests with lots of RAM and not coincidently access
MSI-X mappings while I really want to access RAM.

PPC: e500: Move CCSR and MMIO space to upper end of address space
On e500 we're basically guaranteed to have 36bits of physical address space
available for our enjoyment. Older chips (like the mpc8544) only had 32bits,
but everything from e500v2 onwards bumped it up.
It's reasonably safe to assume that if you're using the PV machine, your guest
kernel is configured to support 36bit physical address space. So in order to
support more guest RAM, we can move CCSR and other MMIO windows right below the
end of our 36bit address space, just like later SoC versions of e500 do.
With this patch, I'm able to successfully spawn an e500 VM with -m 48G.

virtio-serial: Don't keep a persistent copy of config space
The 'config' field in the VirtIOSerial structure keeps a copy of the virtio
console's config space as visible to the guest, that is to say, in guest
endianness. This is fiddly to maintain, because on some targets, such as
powerpc, the "guest endianness" can change when a new guest OS boots.
In fact, there's no need to maintain such a guest view of config space -
instead we can reconstruct it from host-format data when it is accessed
with get_config.

virtio_serial: Don't use vser->config.max_nr_ports internally
A number of places in the virtio_serial driver retrieve the number of ports
from vser->config.max_nr_ports, which is guest-endian. But for internal
users, we already have a host-endian copy of the number of ports in
vser->serial.max_virtserial_ports. Using that instead of the config field
removes the need for easy-to-forget byteswapping.
In particular this fixes a bug on incoming migration, where we don't adjust
the endianness vser->config correctly, because it hasn't yet been loaded
from the migration stream when virtio_serial_load_device() is called.

pckbd: set bits 2-3-6-7 of the output port by default
OSes typically write 0xdd/0xdf to turn the A20 line off and on. This
has bits 2-3-6-7 on, so that the output port subsection is migrated.
Change the reset value and migration default to include those four
bits, thus avoiding that the subsection is migrated.
This strictly speaking changes guest ABI, but the long time during which
we have not migrated the value means that the guests really do not care
much; so the change is for all machine types.

hw/arm: pass pristine kernel image to guest firmware over fw_cfg
Introduce the new boolean field "arm_boot_info.firmware_loaded". When this
field is set, it means that the portion of guest DRAM that the VCPU
normally starts to execute, or the pflash chip that the VCPU normally
starts to execute, has been populated by board-specific code with
full-fledged guest firmware code, before the board calls
arm_load_kernel().
Simultaneously, "arm_boot_info.firmware_loaded" guarantees that the board
code has set up the global firmware config instance, for arm_load_kernel()
to find with fw_cfg_find().
Guest kernel (-kernel) and guest firmware (-bios, -pflash) has always been
possible to specify independently on the command line. The following cases
should be considered:
nr -bios -pflash -kernel description
unit#0
-- ------- ------- ------- -------------------------------------------
1 present present absent Board code rejects this case, -bios and
present present present -pflash unit#0 are exclusive. Left intact
by this patch.
2 absent absent present Traditional kernel loading, with qemu's
minimal board firmware. Left intact by this
patch.
3 absent present absent Preexistent case for booting guest firmware
present absent absent loaded with -bios or -pflash. Left intact
by this patch.
4 absent absent absent Preexistent case for not loading any
firmware or kernel up-front. Left intact by
this patch.
5 present absent present New case introduced by this patch: kernel
absent present present image is passed to externally loaded
firmware in unmodified form, using fw_cfg.
An easy way to see that this patch doesn't interfere with existing cases
is to realize that "info->firmware_loaded" is constant zero at this point.
Which makes the "outer" condition unchanged, and the "inner" condition
(with the fw_cfg-related code) dead.

arm: add fw_cfg to "virt" board
fw_cfg already supports exposure over MMIO (used in ppc/mac_newworld.c,
ppc/mac_oldworld.c, sparc/sun4m.c); we can easily add it to the "virt"
board.
Because MMIO access is slow on ARM KVM, we enable the guest, with
fw_cfg_init_mem_wide(), to transfer up to 8 bytes with a single access.
This has been measured to speed up transfers up to 7.5-fold, relative to
single byte data access, on both ARM KVM and x86_64 TCG.
The MMIO register block of fw_cfg is advertized in the device tree. As
base address we pick 0x09020000, which conforms to the comment preceding
"a15memmap": it falls in the miscellaneous device I/O range 128MB..256MB,
and it is aligned at 64KB. The DTB properties follow the documentation in
the Linux source file "Documentation/devicetree/bindings/arm/fw-cfg.txt".
fw_cfg automatically exports a number of files to the guest; for example,
"bootorder" (see fw_cfg_machine_reset()).

Remember this is big endian. On big endian machines, it is stored
directly as 0x46 0x00 0xcb 0x32.
On a little endian machine, we have to first swap it, so that it becomes
0x32cb0046. When written to memory, it becomes 0x46 0x00 0xcb 0x32
again.
Reading byte-by-byte works too, of course:
>>> readb 0x9020000
<<< OK 0x0000000000000038
>>> readb 0x9020000
<<< OK 0x00000000000000ec
Here only a single byte is read at a time, so they are read in order
similar to the 1-byte data port that is already in PPC and SPARC
machines.

fw_cfg_mem: introduce the "data_width" property
The "data_width" property is capable of changing the maximum valid access
size to the MMIO data register, and resizes the memory region similarly,
at device realization time.
The default value of "data_memwidth" is set so that we don't yet diverge
from "fw_cfg_data_mem_ops".
Most of the fw_cfg_mem users will stick with the default, and for them we
should continue using the statically allocated "fw_cfg_data_mem_ops". This
is beneficial for debugging because gdb can resolve pointers referencing
static objects to the names of those objects.

fw_cfg_mem: flip ctl_mem_ops and data_mem_ops to DEVICE_BIG_ENDIAN
The standalone selector port (fw_cfg_ctl_mem_ops) is only used by big
endian guests to date (*), hence this change doesn't regress them. Paolo
and Alex have suggested / requested an explicit DEVICE_BIG_ENDIAN setting
here, for clarity.
(*) git grep -l fw_cfg_init_mem
hw/nvram/fw_cfg.c
hw/ppc/mac_newworld.c
hw/ppc/mac_oldworld.c
hw/sparc/sun4m.c
include/hw/nvram/fw_cfg.h
The standalone data port (fw_cfg_data_mem_ops) has max_access_size 1 (for
now), hence changing its endianness doesn't change behavior for existing
guest code.

fw_cfg: hard separation between the MMIO and I/O port mappings
We are going to introduce a wide data register for fw_cfg, but only for
the MMIO mapped device. The wide data register will also require the
tightening of endiannesses.
However we don't want to touch the I/O port mapped fw_cfg device at all.
Currently QEMU provides a single fw_cfg device type that can handle both
I/O port and MMIO mapping. This flexibility is not actually exploited by
any board in the tree, but it renders restricting the above changes to
MMIO very hard.
Therefore, let's derive two classes from TYPE_FW_CFG: TYPE_FW_CFG_IO and
TYPE_FW_CFG_MEM.
TYPE_FW_CFG_IO incorporates the base I/O port and the related combined
MemoryRegion. (NB: all boards in the tree that use the I/O port mapped
flavor opt for the combined mapping; that is, when the data port overlays
the high address byte of the selector port. Therefore we can drop the
capability to map those I/O ports separately.)
TYPE_FW_CFG_MEM incorporates the base addresses for the MMIO selector and
data registers, and their respective MemoryRegions.
The "realize" and "props" class members are specific to each new derived
class, and become unused for the base class. The base class retains the
"reset" member and the "vmsd" member, because the reset functionality and
the set of migrated data are not specific to the mapping.
The new functions fw_cfg_init_io() and fw_cfg_init_mem() expose the
possible mappings in separation. For now fw_cfg_init() is retained as a
compatibility shim that enforces the above assumptions.

hw/vfio/pci: split vfio_get_device
vfio_get_device now takes a VFIODevice as argument. The function is split
into 2 parts: vfio_get_device which is generic and vfio_populate_device
which is bus specific.
3 new fields are introduced in VFIODevice to store dev_info.
vfio_put_base_device is created.

hw/vfio/pci: Introduce VFIORegion
This structure is going to be shared by VFIOPCIDevice and
VFIOPlatformDevice. VFIOBAR includes it.
vfio_eoi becomes an ops of VFIODevice specialized by parent device.
This makes possible to transform vfio_bar_write/read into generic
vfio_region_write/read that will be used by VFIOPlatformDevice too.
vfio_mmap_bar becomes vfio_map_region

hw/vfio/pci: handle reset at VFIODevice
Since we can potentially have both PCI and platform devices in
the same VFIO group, this latter now owns a list of VFIODevices.
A unified reset handler, vfio_reset_handler, is registered, looping
through this VFIODevice list. 2 specialized operations are introduced
(vfio_compute_needs_reset and vfio_hot_reset_multi): they allow to
implement type specific behavior. also reset_works and needs_reset
VFIOPCIDevice fields are moved into VFIODevice.

hw/vfio/pci: add type, name and group fields in VFIODevice
Add 3 new fields in the VFIODevice struct. Type is set to
VFIO_DEVICE_TYPE_PCI. The type enum value will later be used
to discriminate between VFIO PCI and platform devices. The name is
set to domain:bus:slot:function. Currently used to test whether
the device already is attached to the group. Later on, the name
will be used to simplify all traces. The group is simply moved
from VFIOPCIDevice to VFIODevice.

exec: change default exception_index value for migration to -1
In QEMU 2.2 the exception_index value was added to the migration stream
through a subsection. The default was set to 0, which is wrong and
should have been -1.
However, 2.2 does not have commit e511b4d (cpu-exec: reset exception_index
correctly, 2014-11-26), hence in 2.2 the exception_index is never used
and is set to -1 on the next call to cpu_exec. So we can change the
migration stream to make the default -1. The effects are:
- 2.2.1 -> 2.2.0: cpu->exception_index set incorrectly to 0 if it
were -1 on the source; then reset to -1 in cpu_exec. This is TCG
only; KVM does not use exception_index.
- 2.2.0 -> 2.2.1: cpu->exception_index set incorrectly to -1 if it
were 0 on the source; but it would be reset to -1 in cpu_exec anyway.
This is TCG only; KVM does not use exception_index.
- 2.2.1 -> 2.1: two bugs fixed: 1) can migrate backwards if
cpu->exception_index is set to -1; 2) should not migrate backwards
(but 2.2.0 allows it) if cpu->exception_index is set to 0
- 2.2.0 -> 2.3.0: 2.2.0 will send the subsection unnecessarily if
exception_index is -1, but that is not a problem. 2.3.0 will set
cpu->exception_index to -1 if it is 0 on the source, but this would
be anyway a problem for 2.2.0 -> 2.2.x migration (due to lack of
commit e511b4d in 2.2.x) so we can ignore it
- 2.2.1 -> 2.3.0: everything works.
In addition, play it safe and never send the subsection unless TCG

in it for use in the subsequent call to ppc_cpu_do_interrupt, but
does not need it as soon as kvm_handle_debug returns). Xen and
qtest do not run any code for the CPU at all.

hw/vfio/pci: introduce minimalist VFIODevice with fd
Introduce a new base VFIODevice strcut that will be used by both PCI
and Platform VFIO device. Move VFIOPCIDevice fd field there. Obviously
other fields from VFIOPCIDevice will be moved there but this patch
file is introduced to ease the review.
Also vfio_mask_single_irqindex, vfio_unmask_single_irqindex,
vfio_disable_irqindex now take a VFIODevice handle as argument.

hw/vfio/pci: generalize mask/unmask to any IRQ index
To prepare for platform device introduction, rename vfio_mask_intx

unmask_single_irqindex. Also use a nex index parameter.
With that name and prototype the function will be usable for other

net: Use g_new() & friends where that makes obvious sense
g_new(T, n) is neater than g_malloc(sizeof(T) * n). It's also safer,
for two reasons. One, it catches multiplication overflowing size_t.
Two, it returns T * rather than void *, which lets the compiler catch
more type errors.
This commit only touches allocations with size arguments of the form
sizeof(T).

net: don't use set/get_pointer() in set/get_netdev()
Commit 1ceef9f27359cbe92ef124bf74de6f792e71f6fb (net: multiqueue
support) tries to use set_pointer() and get_pointer() to set and get
NICPeers which is not a pointer defined in DEFINE_PROP_NETDEV. This
trick works but result a unclean and fragile implementation (e.g
print_netdev and parse_netdev).
This patch solves this issue by not using set/get_pinter() and set and
get netdev directly in set_netdev() and get_netdev(). After this the
parse_netdev() and print_netdev() were no longer used and dropped from
the source.

sdl2: Work around SDL2 SDL_ShowWindow() bug
Apparently it is possible for X to send an event to a hidden SDL2
window, leading to SDL2 believing it is now shown. SDL2 will pass the
SDL_WINDOWEVENT_SHOWN message to the application without actually
showing the window; the problem is that the next SDL_ShowWindow() will
be a no-op because SDL2 assumes the window is already shown.
The correct way to react to SDL_WINDOWEVENT_SHOWN would be to clear
scon->hidden (analogous for SDL_WINDOWEVENT_HIDDEN). However, due to the
window not actually being shown, this will somehow not be correct after
all.
Therefore, just hide the window on SDL_WINDOWEVENT_SHOWN if it is
supposed to be hidden (and analogous for SDL_WINDOWEVENT_HIDDEN).

sdl2: Use correct sdl2_console for window events
SDL_PollEvent() polls events for all windows; therefore,
sdl2_poll_events() will poll the events for all windows and not only for
the one identified by the given sdl2_console.
This should be considered in handle_windowevent(): The window affected
by the event is not necessarily the one identified by the sdl2_console
object given to sdl2_poll_events(), but the one identified by
ev->window.windowID.

sdl2: overhaul window size handling
Split do_sdl_resize function (which does alot more than just resizing)
into three: sdl2_window_{create,destroy,resize}.
Fix SDL_Renderer handling: must be guest display size not host window
size, and SDL2 will magically handle all scaling for us.
Make fullscreen actually enter fullscreen mode and simplify the code.
There is no need to store the original window size, the window manager
will do that for us.

spice: fix memory leak
If errors happen for middle items of channel_list,
qmp_query_spice_channels() returns NULL, and the variable
cur_item going out of scope leaks the storage it points to.
The flag is a compatibility thing for older spice-server
versions. Meanwhile our minimum spice version requirement is
new enough that we should never ever see this error, and if we
do something went very seriously wrong. Let's using assert()
instead of returning NULL to avoid a memory leak.

target-mips: Fix CP0.Config3.ISAOnExc write accesses
Fix CP0.Config3.ISAOnExc write accesses on microMIPS processors. This
bit is mandatory for any processor that implements the microMIPS
instruction set. This bit is r/w for processors that implement both the
standard MIPS and the microMIPS instruction set. This bit is r/o and
hardwired to 1 if only the microMIPS instruction set is implemented.
There is no other bit ever writable in CP0.Config3 so defining a
corresponding `CP0_Config3_rw_bitmask' member in `CPUMIPSState' is I
think an overkill. Therefore make the ability to write the bit rely on
the presence of ASE_MICROMIPS set in the instruction flags.
The read-only case of the microMIPS instruction set being implemented
only can be added when we add support for such a configuration. We do
not currently have such support, we have no instruction flag that would
control the presence of the standard MIPS instruction set nor any
associated code in instruction decoding.
This change is needed to boot a microMIPS Linux kernel successfully,
otherwise it hangs early on as interrupts are enabled and then the
exception handler invoked loops as its first instruction is interpreted
in the wrong execution mode and triggers another exception right away.
And then over and over again.
We already check the current setting of the CP0.Config3.ISAOnExc in
`set_hflags_for_handler' to set the ISA bit correctly on the exception
handler entry so it is the ability to set it that is missing only.

target-mips: Fix the 64-bit case for microMIPS MOVE16 and MOVEP
Fix microMIPS MOVE16 and MOVEP instructions on 64-bit processors by
using register addition operations.
This copies the approach taken with MIPS16 MOVE instructions (I8_MOV32R
and I8_MOVR32 opcodes) and follows the observation that OPC_ADDU expands
to tcg_gen_mov_tl whenever `rt' is 0 and `rs' is not, therefore copying
`rs' to `rd' verbatim. This is not the case with OPC_ADDIU where a
sign-extension from bit #31 is made, unless in the uninteresting case of
`rs' being 0, losing the upper 32 bits of the value copied for any
proper 64-bit values.
This also serves as an optimization as one op is produced in generated
code rather than two (again, unless `rs' is 0, where it doesn't change
anything).

target-mips: Correct the writes to Status and Cause registers via gdbstub
Make writes to CP0.Status and CP0.Cause have the same effect as
executing corresponding MTC0 instructions would in Kernel Mode. Also
ignore writes in the user emulation mode.
Currently for requests from the GDB stub we write all the bits across
both registers, ignoring any read-only locations, and do not synchronise
the environment to evaluate side effects. We also write these registers
in the user emulation mode even though a real kernel presents them as
read only.

target-mips: Correct the handling of writes to CP0.Status for MIPSr6
Correct these issues with the handling of CP0.Status for MIPSr6:
* only ignore the bit pattern of 0b11 on writes to CP0.Status.KSU, that
is for processors that do implement Supervisor Mode, let the bit
pattern be written to CP0.Status.UM:R0 freely (of course the value
written to read-only CP0.Status.R0 will be discarded anyway); this is
in accordance to the relevant architecture specification[1],
* check the newly written pattern rather than the current contents of
CP0.Status for the KSU bits being 0b11,
* use meaningful macro names to refer to CP0.Status bits rather than
magic numbers.

target-mips: Correct MIPS16/microMIPS branch size calculation
Correct MIPS16/microMIPS branch size calculation in PC adjustment
needed:
- to set the value of CP0.ErrorEPC at the entry to the reset exception,
- for the purpose of branch reexecution in the context of device I/O.
Follow the approach taken in `exception_resume_pc' for ordinary, Debug
and NMI exceptions.
MIPS16 and microMIPS branches can be 2 or 4 bytes in size and that has
to be reflected in calculation. Original MIPS ISA branches, which is
where this code originates from, are always 4 bytes long, just as all
original MIPS ISA instructions.

target-mips: Restore the order of helpers
Restore the order of helpers that used to be: unary operations (generic,
then MIPS-specific), binary operations (generic, then MIPS-specific),
compare operations. At one point FMA operations were inserted at a
random place in the file, disregarding the preexisting order, and later
on even more operations sprinkled across the file. Revert the mess by
moving FMA operations to a new ternary class inserted after the binary
class and move the misplaced unary and binary operations to where they
belong.

target-mips: Add M14K and M14Kc MIPS32r2 microMIPS processors
Add the M14K and M14Kc processors from MIPS Technologies that are the
original implementation of the microMIPS ISA. They are dual instruction
set processors, implementing both the microMIPS and the standard MIPSr32
ISA.
These processors correspond to the M4K and 4KEc CPUs respectively,
except with support for the microMIPS instruction set added, support for
the MCU ASE added and two extra interrupt lines, making a total of 8
hardware interrupts plus 2 software interrupts. The remaining parts of
the microarchitecture, in particular the pipeline, stayed unchanged.
The presence of the microMIPS ASE is is reflected in the configuration
added. We currently have no support for the MCU ASE, including in
particular the ACLR, ASET and IRET instructions in either encoding, and
we have no support for the extra interrupt lines, including bits in
CP0.Status and CP0.Cause registers, so these features are not marked,
making our support diverge from real hardware.

target-mips: Add 5KEc and 5KEf MIPS64r2 processors
Add the 5KEc and 5KEf processors from MIPS Technologies that are the
original implementation of the MIPS64r2 ISA.
Silicon for these processors has never been taped out and no soft cores
were released even. They do exist though, a CP0.PRId value has been
assigned and experimental RTLs produced at the time the MIPS64r2 ISA has
been finalized. The settings introduced here faithfully reproduce that
hardware.
As far the implementation goes these processors are the same as the 5Kc
and the 5Kf CPUs respectively, except implementing the MIPS64r2 rather
than the original MIPS64 instruction set. There must have been some
updates to the CP0 architecture as mandated by the ISA, such as the
addition of the EBase register, although I am not sure about the exact
details, no documentation has ever been produced for these processors.
The remaining parts of the microarchitecture, in particular the
pipeline, stayed unchanged. Or to put it another way, the difference
between a 5K and a 5KE CPU corresponds to one between a 4K and a 4KE
CPU, except for the 64-bit rather than 32-bit ISA.

Start migrating migration code into a migration directory
The migration code now occupies a fair chunk of the top level .c
files, it seems time to give it it's own directory.
I've not touched:
arch_init.c - that's mostly RAM migration but has a few random other
bits
savevm.c - because it's built target specific
This is purely a code move; no code has changed.
- it fails checkpatch because of old violations, it feels safer
to keep this as purely a move and fix those at some mythical future
date.
The xbzrle and vmstate tests are now only run for softmmu builds
since they require files in the migrate/ directory which is only built
for softmmu.

Remove the virtual methods and replace them with direct calls to the

serial: only resample THR interrupt on rising edge of IER.THRI
There is disagreement on whether LSR.THRE should be resampled when
IER.THRI goes from 1 to 1. Bochs only does it if IER.THRI goes from 0
to 1; PCE does it even if IER.THRI is unchanged. But the Windows driver
seems to always go from 1 to 0 and back to 1, so do things in agreement
with Bochs, because the handling of thr_ipending was reported in 2010
(https://lists.gnu.org/archive/html/qemu-devel/2010-03/msg01914.html)
as breaking DR-DOS Plus.

serial: update LSR on enabling/disabling FIFOs
When the transmit FIFO is emptied or enabled, the transmitter
hold register is empty. When it is disabled, it is also emptied and
in addition the previous contents of the transmitter hold register
are discarded. In either case, the THRE bit in LSR must be set and
THRI raised.
When the receive FIFO is emptied or enabled, the data ready and break
bits must be cleared in LSR. Likewise when the receive FIFO is disabled.

serial: clean up THRE/TEMT handling
- assert TEMT is cleared before sending a character; we'll get one from
TSR if tsr_retry > 0, from the FIFO or THR otherwise
- assert THRE cleared and FIFO not empty (if enabled) before fetching a
character to send. This effectively reverts dffacd46, but the check
makes no sense and commit f702e62 (serial: change retry logic to avoid
concurrency, 2014-07-11) must have made it unnecessary. The commit
message for f702e62 talks about multiple calls to qemu_chr_fe_add_watch
triggering s->tsr_retry >= MAX_XMIT_RETRY, but other failures were
possible. For example, if you have multiple calls, the subsequent ones
will see s->tsr_retry == 0 and will find THRE and/or TEMT on entry.
- for clarity, raise THRI immediately after the code sets THRE
- check THRE to see if another character has to be sent. This makes
the assertions more obvious and also means TEMT has to be set as soon as
the loop ends. It makes the loop send both TSR and THR if flow-control
happens in non-FIFO mode. Previously, THR would be lost.
- clear TEMT together with THRE even in the non-FIFO case
The last two items are bugfixes, but they were just found by inspection
and do not squash known bugs.

serial: reset thri_pending on IER writes with THRI=0
This is responsible for failure of migration from 2.2 to 2.1, because
thr_ipending is always one in practice.
serial.c is setting thr_ipending unconditionally. However, thr_ipending
is not used at all if THRI=0, and it will be overwritten again the next
time THRE or THRI changes. For that reason, we can set thr_ipending to
zero every time THRI is reset.
There is disagreement on whether LSR.THRE should be resampled when IER.THRI
goes from 1 to 1. This patch does not touch the code, leaving that for
QEMU 2.3+.
This has no semantic change and is enough to fix migration in the common
case where the interrupt is not pending or is reported in IIR. It does not
change the migration format, so 2.2.0 -> 2.1 will remain broken but we
can fix 2.2.1 -> 2.1 without breaking 2.2.1 <-> 2.2.0.
The case that remains broken (the one in which the subsection is strictly
necessary) is when THRE=1, the THRI interrupt has *not* been acknowledged
yet, and a higher-priority interrupt comes. In this case, you need the
subsection to tell the source that the lower-priority THRI interrupt is
pending. The subsection's breakage of migration, in this case, prevents
continuing the VM on the destination with an invalid state.

linuxboot: fix loading old kernels
Old kernels that used high memory only allowed the initrd to be in the
first 896MB of memory. If you load the initrd above, they complain
that "initrd extends beyond end of memory".
In order to fix this, while not breaking machines with small amounts
of memory fixed by cdebec5 (linuxboot: compute initrd loading address,
2014-10-06), we need to distinguish two cases. If pc.c placed the
initrd at end of memory, use the new algorithm based on the e801
memory map. If instead pc.c placed the initrd at the maximum address
specified by the bzImage, leave it there.
The only interesting part is that the low-memory info block is now
loaded very early, in real mode, and thus the 32-bit address has
to be converted into a real mode segment. The initrd address is
also patched in the info block before entering real mode, it is
simpler that way.
This fixes booting the RHEL4.8 32-bit installation image with 1GB
of RAM.

In icount mode cpu_exec_nocache function is used to execute part of the

Sometimes io_read function needs to recompile current TB and restart TB
lookup and execution. After that tb_find_fast function finds old (bigger)
TB again. This TB cannot be executed (because icount is not big enough)
and cpu_exec_nocache is called again. Such a loop continues over and over.

KVM_CAP_IRQFD and KVM_CAP_IRQFD_RESAMPLE checks
Compute kvm_irqfds_allowed by checking the KVM_CAP_IRQFD extension.
Remove direct settings in architecture specific files.
Add a new kvm_resamplefds_allowed variable, initialized by
checking the KVM_CAP_IRQFD_RESAMPLE extension. Add a corresponding
kvm_resamplefds_enabled() function.
A special notice for s390 where KVM_CAP_IRQFD was not immediatly
advirtised when irqfd capability was introduced in the kernel.
KVM_CAP_IRQ_ROUTING was advertised instead.
This was fixed in "KVM: s390: announce irqfd capability",
ebc3226202d5956a5963185222982d435378b899 whereas irqfd support
was brought in 84223598778ba08041f4297fda485df83414d57e,
"KVM: s390: irq routing for adapter interrupts". Both commits
first appear in 3.15 so there should not be any kernel
version impacted by this QEMU modification.

target-i386: fix icount processing for repz instructions
TCG generates optimized code for i386 repz instructions in single step mode.
It means that when ecx becomes 0, execution of the string instruction breaks
immediately without an additional iteration for ecx==0 (which will only check
ecx and set the flags). Omitting this iteration leads to different
instructions counting in singlestep mode and in normal execution.
This patch disables optimization of this last iteration for icount mode
which should be deterministic.

Avoid that unplug submits requests when io_submit reported that it
couldn't accept more; at the same time, try more io_submit calls if it
could handle the whole set of requests that were passed, so that the
"blocked" flag is reset as soon as possible.
After the previous patch, laio_submit already tried to avoid submitting
requests to a blocked queue, by comparing s->io_q.idx with "==" instead
of the more natural ">=". Switch to the simpler expression now that we
have the "blocked" flag.

qemu-io: Add sigraise command
abort() has the sometimes undesirable side-effect of generating a core
dump. If that is not needed, SIGKILL has the same effect of abruptly
crash qemu; without a core dump.
Thus, -c abort is not always useful to simulate a qemu-io crash;
therefore, this patch adds a new sigraise command which allows raising
a signal.

block: vhdx - change .vhdx_create default block state to ZERO
The VHDX spec specifies that the default new block state is
PAYLOAD_BLOCK_NOT_PRESENT for a dynamic VHDX image, and
PAYLOAD_BLOCK_FULLY_PRESENT for a fixed VHDX image.
However, in order to create space-efficient VHDX images with qemu-img
convert, it is desirable to be able to set has_zero_init to true for
VHDX.
There is currently an option when creating VHDX images, to use block
state ZERO for new blocks. However, this currently defaults to 'off'.
In order to be able to eventually set has_zero_init to true for VHDX,
this needs to default to 'on'.
This patch changes the default to 'on', and provides some help
information to warn against setting it to 'off' when using qemu-img
convert.
[Max Reitz pointed out that a full stop was missing at the end of the
VHDX_BLOCK_OPT_ZERO option help text. I have added it.

block: vhdx - update PAYLOAD_BLOCK_UNMAPPED value to match 1.00 spec
The 0.95 VHDX spec defined PAYLOAD_BLOCK_UNMAPPED to be 5. The 1.00
VHDX spec redefines PAYLOAD_BLOCK_UNMAPPED to be 3 instead.
The original value of 5 is now an undefined state in the spec, but it
should be safe to treat it the same and return zeros for data read.
This way, we can maintain compatibility with any images out in the wild
that may have been created in accordance to the 0.95 spec.

vmdk: Fix error for JSON descriptor file names
If vmdk blindly tries to use path_combine() using bs->file->filename as
the base file name, this will result in a bad error message for JSON
file names when calling bdrv_open(). It is better to only try
bs->file->exact_filename; if that is empty, bs->file->filename will be
useless for path_combine() and an error should be emitted (containing
bs->file->filename because desc_file_path (which is
bs->file->exact_filename) is empty).

target-arm: Check error conditions on kvm_arm_reset_vcpu
When resetting a VCPU we currently call both kvm_arm_vcpu_init() and
write_kvmstate_to_list(), both of which can fail, but we never check the
return value.
The only choice here is to print an error an exit if the calls fail.

target-arm: Support save/load for 64 bit CPUs
For migration to work on 64 bit CPUs, we need to include both
the 64-bit integer register file and the PSTATE. Everything
else is either stored in the same place as existing 32-bit CPU
state or handled by the generic sysreg mechanism.

target-arm/kvm: make reg sync code common between kvm32/64
Before we launch a guest we query KVM for the list of "co-processor"
registers it knows about. This is used to synchronize system
register state for the bulk of coprocessor/system registers.
Move this code from the 32-bit specific vcpu init function into
a common routine and call it also from the 64-bit vcpu init.
This allows system registers to migrate correctly when using
KVM, and also permits QEMU code to see the current KVM register
state (which will be needed to support big-endian guests, since
the virtio endianness callback must check for some system register
settings).
Since vcpu reset also has to sync registers, we move the
32 bit kvm_arm_reset_vcpu() into common code as well and
share it with the 64 bit version.

[PMM: just copy the 32-bit code rather than improving it along the way;
don't share reg_syncs_via_tuple_list() between 32 and 64 bit;
tweak function names; move reset]

hw/arm/boot: fix uninitialized scalar variable warning reported by coverity
Coverity reports the 'size' may be used uninitialized, but that can't happen,
because the caller has checked "if (binfo->dtb_filename || binfo->get_dtb)"
before call 'load_dtb'.
Here we simply remove the 'if (binfo->get_dtb)' to satisfy coverity.

hw/arm/realview.c: Fix memory leak in realview_init()
Variable 'ram_lo' is allocated unconditionally, but used only in some cases.
When it is unused pointer will be lost at function exit, resulting in a
memory leak. Allocate memory for 'ram_lo' only if it is needed.

target-arm: add banked register accessors
If EL3 is in AArch32 state certain cp registers are banked (secure and
non-secure instance). When reading or writing to coprocessor registers
the following macros can be used.
- A32_BANKED macros are used for choosing the banked register based on provided
input security argument. This macro is used to choose the bank during
translation of MRC/MCR instructions that are dependent on something other
than the current secure state.
- A32_BANKED_CURRENT macros are used for choosing the banked register based on
current secure state. This is NOT to be used for choosing the bank used
during translation as it breaks monitor mode.
If EL3 is operating in AArch64 state coprocessor registers are not
banked anymore. The macros use the non-secure instance (_ns) in this
case, which is architecturally mapped to the AArch64 EL register.

Add the "-semihosting-config" option.
The usual semihosting behaviour is to process the system calls locally and
return; unfortuantelly the initial implementation dinamically changed the
target to GDB during debug sessions, which, for the usual arm-none-eabi-gdb,
is not implemented. The result was that during debug sessions the semihosting
calls were discarded.
This patch adds a configuration variable and an option to set it on the
command line:
-semihosting-config [enable=on|off,]target=native|gdb|auto
This option enables semihosting and defines where the semihosting calls will
be addressed, to QEMU ('native') or to GDB ('gdb'). The default is auto, which
means 'gdb' during debug sessions and 'native' otherwise.

Pass semihosting exit code back to system.
In order to run unit tests under semihosting, it is necessary to pass the
application exit code back to the system.
ARM defines only the code to be used for non-error application exit
(ADP_Stopped_ApplicationExit), all other codes should return non-zero
exit codes.
This patch checks if the application code passed via TARGET_SYS_EXIT is
ADP_Stopped_ApplicationExit, and return 0, otherwise return 1.

This replaces two "time(NULL)" invocations with "g_random_int()".
According to VMDK spec, CID "is a random 32‐bit value updated the first
time the content of the virtual disk is modified after the virtual disk
is opened". Using "seconds since epoch" is just a "lame way" to generate
it, and not completely safe because of the low precision.

this is not something that should really work; qemu-img should check

ide: Check validity of logical block size
Our IDE emulation can't handle logical block sizes other than 512. Check

The original assumption was that other values would silently be ignored
(which is bad enough), but it's not quite true: The physical block size
is exposed in IDENTIFY DEVICE as a multiple of the logical block size.
Setting a logical block size therefore also corrupts the physical block
size (4096/4096 doesn't silently downgrade to 4096/512, but 512/512).

blockdev: acquire AioContext in QMP 'transaction' actions
The transaction QMP command performs operations atomically on a group of
drives. This command needs to acquire AioContext in order to work
safely when virtio-blk dataplane IOThreads are accessing drives.
The transactional nature of the command means that actions are split
into prepare, commit, abort, and clean functions. Acquire the
AioContext in prepare and don't release it until one of the other
functions is called. This prevents the IOThread from running the
AioContext before the transaction has completed.

raw: Prohibit dangerous writes for probed images
If the user neglects to specify the image format, QEMU probes the
image to guess it automatically, for convenience.
Relying on format probing is insecure for raw images (CVE-2008-2004).
If the guest writes a suitable header to the device, the next probe
will recognize a format chosen by the guest. A malicious guest can
abuse this to gain access to host files, e.g. by crafting a QCOW2
header with backing file /etc/shadow.
Commit 1e72d3b (April 2008) provided -drive parameter format to let
users disable probing. Commit f965509 (March 2009) extended QCOW2 to
optionally store the backing file format, to let users disable backing
file probing. QED has had a flag to suppress probing since the
beginning (2010), set whenever a raw backing file is assigned.
All of these additions that allow to avoid format probing have to be
specified explicitly. The default still allows the attack.
In order to fix this, commit 79368c8 (July 2010) put probed raw images
in a restricted mode, in which they wouldn't be able to overwrite the
first few bytes of the image so that they would identify as a different
image. If a write to the first sector would write one of the signatures
of another driver, qemu would instead zero out the first four bytes.
This patch was later reverted in commit 8b33d9e (September 2010) because
it didn't get the handling of unaligned qiov members right.
Today's block layer that is based on coroutines and has qiov utility
functions makes it much easier to get this functionality right, so this
patch implements it.
The other differences of this patch to the old one are that it doesn't
silently write something different than the guest requested by zeroing
out some bytes (it fails the request instead) and that it doesn't
maintain a list of signatures in the raw driver (it calls the usual
probe function instead).
Note that this change doesn't introduce new breakage for false positive
cases where the guest legitimately writes data into the first sector
that matches the signatures of an image format (e.g. for nested virt):
These cases were broken before, only the failure mode changes from
corruption after the next restart (when the wrong format is probed) to
failing the problematic write request.
Also note that like in the original patch, the restrictions only apply
if the image format has been guessed by probing. Explicitly specifying a
format allows guests to write anything they like.

block: Read only one sector for format probing
The only image format driver that even potentially accesses anything
after 512 bytes in its bdrv_probe() implementation is VMDK, which reads
a plain-text descriptor file. In practice, the field it's looking for
seems to come first and will be well within the first 512 bytes, too.

qemu-iotests: Use qemu-io -f $IMGFMT
This patch changes $QEMU_IO so that all tests by default pass a format
argument to qemu-io.
There are a few cases where -f $IMGFMT is not wanted because it selects
the wrong driver or json: filenames including a driver are used. They
are changed to use $QEMU_IO_PROG, which doesn't include any options.
Tests 071 and 081 have output changes because now the actual request
fails instead of reading the 2k probing buffer.

qemu-nbd: Use BlockBackend where reasonable
Because qemu-nbd creates the BlockBackend by itself, it should create
the according BlockDriverState tree by itself as well; that means, it
has call bdrv_open() on its own. This is one of the places where
qemu-nbd still needs to use a BlockDriverState directly (the root BDS
below the BB); other places are the configuration of zero detection
(which may be lifted into the BB eventually, but is not yet) and
temporarily loading a snapshot.
Everywhere else, though, qemu-nbd can and thus should use BlockBackend.

block: Add blk_add_close_notifier() for BB
Adding something like a "delete notifier" to a BlockBackend would not
make much sense, because whoever is interested in registering there will
probably hold a reference to that BlockBackend; therefore, the notifier
will never be called (or only when the notifiee already relinquished its
reference and thus most probably is no longer interested in that
notification).
Therefore, this patch just passes through the close notifier interface
of the root BDS. This will be called when the device is ejected, for
instance, and therefore does make sense.

ahci: avoid #ifdef DEBUG_AHCI bitrot
Debug code using #ifdef is susceptible to bitrot because the compiler
never checks the debug code.
This is easy to avoid, change the DPRINTF() macro to use if (DEBUG_AHCI)
and always give it a 0 or 1 value.
This also allows us to drop an #ifdef DEBUG_AHCI in ahci_start_dma()
since the compiler can now see the local variable is used.
The motivation for this change is a recent DEBUG_AHCI build failure due
to an outdated DPRINTF() format string. From now on the compiler will
catch these errors.

block: Include "node-name" if present in query-blockstats
Node name is a better identifier of BDS.
We will want to query statistics of a BDS node buried in the BDS graph,
so reporting the node's name if there is one will do the trick.

util: Use g_new() & friends where that makes obvious sense
g_new(T, n) is neater than g_malloc(sizeof(T) * n). It's also safer,
for two reasons. One, it catches multiplication overflowing size_t.
Two, it returns T * rather than void *, which lets the compiler catch
more type errors.
This commit only touches allocations with size arguments of the form
sizeof(T).

spice: surface switch fast path requires same format too.
Commit "555e72f spice: rework mirror allocation, add no-resize fast path"
adds a fast path for surface switches which does't go through the full
primary surface destroy and re-recreation in case the new surface is
identical to the old one (page-flip). It checks the size only though,
but the format must be identical too. This patch adds the format check.
Commit "0002a51 ui/spice: Support shared surface for most pixman
formats" increases the chance to actually trigger this.

xen/HVM: atomically access pointers in bufioreq handling
The number of slots per page being 511 (i.e. not a power of two) means
that the (32-bit) read and write indexes going beyond 2^32 will likely
disturb operation. The hypervisor side gets I/O req server creation
extended so we can indicate that we're using suitable atomic accesses
where needed, allowing it to atomically canonicalize both pointers when
both have gone through at least one cycle.
The Xen side counterpart (which is not a functional prereq to this
change, albeit a build one) went in already (commit b7007bc6f9).

virtio: sync the dataplane vring state to the virtqueue before virtio_save
When creating snapshot with the dataplane enabled, the snapshot file gets
not the actual state of virtqueue, because the current state is stored in
VirtIOBlockDataPlane. Therefore, before saving snapshot need to sync
the dataplane vring state to the virtqueue. The dataplane will resume its
work at the next notify virtqueue.
When snapshot loads with loadvm we get a message:
VQ 0 size 0x80 Guest index 0x15f5 inconsistent with Host index 0x0:
delta 0x15f5
error while loading state for instance 0x0 of device
'0000:00:08.0/virtio-blk'
Error -1 while loading VM state
to reproduce the error I used the following hmp commands:
savevm snap1
loadvm snap1

net: don't set native endianness
commit 5be7d9f1b1452613b95c6ba70b8d7ad3d0797991
vhost-net: tell tap backend about the vnet endianness
makes vhost net always try to set LE - even if that matches the
native endian-ness.
This makes it fail on older kernels on x86 without TUNSETVNETLE support.
To fix, make qemu_set_vnet_le/qemu_set_vnet_be skip the
ioctl if it matches the host endian-ness.

device-introspect-test: New, covering device introspection
The test doesn't check that the output makes any sense, only that QEMU
survives. Useful since we've had an astounding number of crash bugs
around there.
In fact, we have a bunch of them right now: a few devices crash or
hang, and some leave dangling pointers behind. The test skips testing
the broken parts. The next commits will fix them up, and drop the
skipping.

libqtest: New hmp() & friends
New convenience function hmp() to facilitate use of
human-monitor-command in tests. Use it to simplify its existing uses.
To blend into existing libqtest code, also add qtest_hmpv() and
qtest_hmp(). That, and the egregiously verbose GTK-Doc comment format
make this patch look bigger than it is.

tests: Fix how qom-test is run
We want to run qom-test for every architecture, without having to
manually add it to every architecture's list of tests. Commit 3687d53
accomplished this by adding it to every architecture's list
automatically.
However, some architectures inherit their tests from others, like this:
check-qtest-x86_64-y = $(check-qtest-i386-y)
check-qtest-microblazeel-y = $(check-qtest-microblaze-y)
check-qtest-xtensaeb-y = $(check-qtest-xtensa-y)
For such architectures, we ended up running the (slow!) test twice.
Commit 2b8419c attempted to avoid this by adding the test only when
it's not already present. Works only as long as we consider adding
the test to the architectures on the left hand side *after* the ones
on the right hand side: x86_64 after i386, microblazeel after
microblaze, xtensaeb after xtensa.
Turns out we consider them in $(SYSEMU_TARGET_LIST) order. Defined as
SYSEMU_TARGET_LIST := $(subst -softmmu.mak,,$(notdir \
$(wildcard $(SRC_PATH)/default-configs/*-softmmu.mak)))
On my machine, this results in the oder xtensa, x86_64, microblazeel,
microblaze, i386. Consequently, qom-test runs twice for microblazeel
and x86_64.
Replace this complex and flawed machinery with a much simpler one: add
generic tests (currently just qom-test) to check-qtest-generic-y
instead of check-qtest-$(target)-y for every target, then run
$(check-qtest-generic-y) for every target.

macio: move DBDMA_init from instance_init to realize
DBDMA_init is not idempotent, and calling it from instance_init
breaks a simple object_new/object_unref pair. Work around this,

hw: do not pass NULL to memory_region_init from instance_init
This causes the region to outlive the object, because it attaches the
region to /machine. This is not nice for the "realize" method, but
much worse for "instance_init" because it can cause dangling pointers
after a simple object_new/object_unref pair.

memory: allow destroying a non-empty MemoryRegion
This is legal; the MemoryRegion will simply unreference all the
existing subregions and possibly bring them down with it as well.
However, it requires a bit of care to avoid an infinite loop.
Finalizing a memory region cannot trigger an address space update,
but memory_region_del_subregion errs on the side of caution and
might trigger a spurious update: avoid that by resetting mr->enabled
first.

virtio-net: correctly drop truncated packets
When packet is truncated during receiving, we drop the packets but
neither discard the descriptor nor add and signal used
descriptor. This will lead several issues:
- sg mappings are leaked
- rx will be stalled if a lots of packets were truncated
In order to be consistent with vhost, fix by discarding the descriptor
in this case.

Revert "qdev: Use qdev_get_device_class() for -device <type>,help"
This reverts commit 31bed5509dfcbdfc293154ce81086a4dbd7a80b6.
The reverted commit changed qdev_device_help() to reject abstract
devices and devices that have cannot_instantiate_with_device_add_yet
set, to fix crash bugs like -device x86_64-cpu,help.
Rejecting abstract devices makes sense: they're purely internal, and
the implementation of the help feature can't cope with them.
Rejecting non-pluggable devices makes less sense: even though you
can't use them with -device, the help may still be useful elsewhere,
for instance with -global. This is a regression: -device FOO,help
used to help even for FOO that aren't pluggable.
The previous two commits fixed the crash bug at a lower layer, so
reverting this one is now safe. Fixes the -device FOO,help
regression, except for the broken devices marked
cannot_even_create_with_object_new_yet. For those, the error message
is improved.
Example of a device where the regression is fixed:
$ qemu-system-x86_64 -device PIIX4_PM,help
PIIX4_PM.command_serr_enable=bool (on/off)
PIIX4_PM.multifunction=bool (on/off)
PIIX4_PM.rombar=uint32
PIIX4_PM.romfile=str
PIIX4_PM.addr=int32 (Slot and optional function number, example: 06.0 or 06)
PIIX4_PM.memory-hotplug-support=bool
PIIX4_PM.acpi-pci-hotplug-with-bridge-support=bool
PIIX4_PM.s4_val=uint8
PIIX4_PM.disable_s4=uint8
PIIX4_PM.disable_s3=uint8
PIIX4_PM.smb_io_base=uint32
Example of a device where it isn't fixed:
$ qemu-system-x86_64 -device host-x86_64-cpu,help
Can't list properties of device 'host-x86_64-cpu'
Both failed with "Parameter 'driver' expects pluggable device type"

qdev: Protect device-list-properties against broken devices
Several devices don't survive object_unref(object_new(T)): they crash
or hang during cleanup, or they leave dangling pointers behind.
This breaks at least device-list-properties, because
qmp_device_list_properties() needs to create a device to find its
properties. Broken in commit f4eb32b "qmp: show QOM properties in
device-list-properties", v2.1. Example reproducer:
$ qemu-system-aarch64 -nodefaults -display none -machine none -S -qmp stdio
{"QMP": {"version": {"qemu": {"micro": 50, "minor": 4, "major": 2}, "package": ""}, "capabilities": []}}
{ "execute": "qmp_capabilities" }
{"return": {}}
{ "execute": "device-list-properties", "arguments": { "typename": "pxa2xx-pcmcia" } }
qemu-system-aarch64: /home/armbru/work/qemu/memory.c:1307: memory_region_finalize: Assertion `((&mr->subregions)->tqh_first == ((void *)0))' failed.
Aborted (core dumped)
[Exit 134 (SIGABRT)]
Unfortunately, I can't fix the problems in these devices right now.
Instead, add DeviceClass member cannot_destroy_with_object_finalize_yet
to mark them:
* Hang during cleanup (didn't debug, so I can't say why):
"realview_pci", "versatile_pci".
* Dangling pointer in cpus: most CPUs, plus "allwinner-a10", "digic",
"fsl,imx25", "fsl,imx31", "xlnx,zynqmp", because they create such
CPUs
* Assert kvm_enabled(): "host-x86_64-cpu", host-i386-cpu",
"host-powerpc64-cpu", "host-embedded-powerpc-cpu",
"host-powerpc-cpu" (the powerpc ones can't currently reach the
assertion, because the CPUs are only registered when KVM is enabled,
but the assertion is arguably in the wrong place all the same)
Make qmp_device_list_properties() fail cleanly when the device is so
marked. This improves device-list-properties from "crashes, hangs or
leaves dangling pointers behind" to "fails". Not a complete fix, just
a better-than-nothing work-around. In the above reproducer,
device-list-properties now fails with "Can't list properties of device
'pxa2xx-pcmcia'".
This also protects -device FOO,help, which uses the same machinery
since commit ef52358 "qdev-monitor: include QOM properties in -device
FOO, help output", v2.2. Example reproducer:
$ qemu-system-aarch64 -machine none -device pxa2xx-pcmcia,help
Before:
qemu-system-aarch64: .../memory.c:1307: memory_region_finalize: Assertion `((&mr->subregions)->tqh_first == ((void *)0))' failed.
After:

virtio-net: unbreak self announcement and guest offloads after migration
After commit 019a3edbb25f1571e876f8af1ce4c55412939e5d ("virtio: make
features 64bit wide"). Device's guest_features was actually set after
vdc->load(). This breaks the assumption that device specific load()
function can check guest_features. For virtio-net, self announcement
and guest offloads won't work after migration.
Fixing this by defer them to virtio_net_load() where guest_features
were guaranteed to be set. Other virtio devices looks fine.

virtio: avoid leading underscores for helpers
Commit ef546f1275f6563e8934dd5e338d29d9f9909ca6 ("virtio: add
feature checking helpers") introduced a helper __virtio_has_feature.
We don't want to use reserved identifiers, though, so let's
rename __virtio_has_feature to virtio_has_feature and virtio_has_feature
to virtio_vdev_has_feature.

target-ppc: fix xscmpodp and xscmpudp decoding
The xscmpodp and xscmpudp instructions only have the AX, BX bits in
there encoding, the lowest bit (usually TX) is marked as an invalid
bit. We therefore can't decode them with GEN_XX2FORM, which decodes
the two lowest bit.
Introduce a new form GEN_XX2FORM, which decodes AX and BX and mark
the lowest bit as invalid.

target-ppc: fix vcipher, vcipherlast, vncipherlast and vpermxor
For vector instructions, the helpers get pointers to the vector register
in arguments. Some operands might point to the same register, including
the operand holding the result.
When emulating instructions which access the vector elements in a
non-linear way, we need to store the result in an temporary variable.
This fixes openssl when emulating a POWER8 CPU.

tcg/mips: Fix clobbering of qemu_ld inputs
The MIPS TCG backend implements qemu_ld with 64-bit targets using the v0
register (base) as a temporary to load the upper half of the QEMU TLB
comparator (see line 5 below), however this happens before the input
address is used (line 8 to mask off the low bits for the TLB
comparison, and line 12 to add the host-guest offset). If the input
address (addrl) also happens to have been placed in v0 (as in the second
column below), it gets clobbered before it is used.
addrl in t2 addrl in v0

13 lw t0,0(v0) lw t0,0(v0)
Fix by using TCG_TMP0 (at) as the temporary instead of v0 (base),
pushing the load on line 5 forward into the delay slot of the low
comparison (line 10). The early load of the addend on line 7 also needs
pushing even further for 64-bit targets, or it will clobber a0 before
we're done with it. The output for 32-bit targets is unaffected.

then fail to call visit_type_str().

ide: unify io_buffer_offset increments
IDEState's io_buffer_offset was originally added to keep track of offsets
in AHCI rather exclusively, but it was added to IDEState instead of an
AHCI-specific structure.
AHCI fakes all PIO transfers using DMA and a scatter-gather list. When
the core or atapi layers invoke HBA-specific mechanisms for transfers,
they do not always know that it is being backed by DMA or a sglist, so
this offset is not always updated by the HBA code everywhere.
If we modify it in dma_buf_commit, however, any HBA that needs to use
this offset to manage operating on only part of a sglist will have
access to it.
This will fix ATAPI PIO transfers performed through the AHCI HBA,
which were previously not modifying this value appropriately.
This will fix ATAPI PIO transfers larger than one sector.

spapr_pci: fix device tree props for MSI/MSI-X
PAPR requires ibm,req#msi and ibm,req#msi-x to be present in the
device node to define the number of msi/msi-x interrupts the device
supports, respectively.
Currently we have ibm,req#msi-x hardcoded to a non-sensical constant
that happens to be 2, and are missing ibm,req#msi entirely. The result
of that is that msi-x capable devices get limited to 2 msi-x
interrupts (which can impact performance), and msi-only devices likely
wouldn't work at all. Additionally, if devices expect a minimum that
exceeds 2, the guest driver may fail to load entirely.
SLOF still owns the generation of these properties at boot-time
(although other device properties have since been offloaded to QEMU),
but for hotplugged devices we rely on the values generated by QEMU
and thus hit the limitations above.
Fix this by generating these properties in QEMU as expected by guests.
In the future it may make sense to modify SLOF to pass through these
values directly as we do with other props since we're duplicating SLOF
code.

gtk: use setlocale() for LC_MESSAGES only
The QEMU code is not internationalized and assumes that it runs under
the C locale, but if we use the GTK+ UI we'll end up importing the
locale settings from the environment. This can break things, such as
the JSON generator and iotest 120 in locales that use a decimal comma.
We do however have translations for a few simple strings for the GTK+
menu items, so in order to run QEMU using the C locale, and yet have a
translated UI let's use setlocale() for LC_MESSAGES only.

ide: fix ATAPI command permissions
We're a little too lenient with what we'll let an ATAPI drive handle.
Clamp down on the IDE command execution table to remove CD_OK permissions
from commands that are not and have never been ATAPI commands.
For ATAPI command validity, please see:
- ATA4 Section 6.5 ("PACKET Command feature set")
- ATA8/ACS Section 4.3 ("The PACKET feature set")
- ACS3 Section 4.3 ("The PACKET feature set")
ACS3 has a historical command validity table in Table B.4
("Historical Command Assignments") that can be referenced to find when
a command was introduced, deprecated, obsoleted, etc.
The only reference for ATAPI command validity is by checking that
version's PACKET feature set section.
ATAPI was introduced by T13 into ATA4, all commands retired prior to ATA4
therefore are assumed to have never been ATAPI commands.
Mandatory commands, as listed in ATA8-ACS3, are:
- DEVICE RESET
- EXECUTE DEVICE DIAGNOSTIC
- IDENTIFY DEVICE
- IDENTIFY PACKET DEVICE
- NOP
- PACKET
- READ SECTOR(S)
- SET FEATURES
Optional commands as listed in ATA8-ACS3, are:
- FLUSH CACHE
- READ LOG DMA EXT
- READ LOG EXT
- WRITE LOG DMA EXT
- WRITE LOG EXT
All other commands are illegal to send to an ATAPI device and should
be rejected by the device.
CD_OK removal justifications:
0x06 WIN_DSM Defined in ACS2. Not valid for ATAPI.
0x21 WIN_READ_ONCE Retired in ATA5. Not ATAPI in ATA4.
0x94 WIN_STANDBYNOW2 Retired in ATA4. Did not coexist with ATAPI.
0x95 WIN_IDLEIMMEDIATE2 Retired in ATA4. Did not coexist with ATAPI.
0x96 WIN_STANDBY2 Retired in ATA4. Did not coexist with ATAPI.
0x97 WIN_SETIDLE2 Retired in ATA4. Did not coexist with ATAPI.
0x98 WIN_CHECKPOWERMODE2 Retired in ATA4. Did not coexist with ATAPI.
0x99 WIN_SLEEPNOW2 Retired in ATA4. Did not coexist with ATAPI.
0xE0 WIN_STANDBYNOW1 Not part of ATAPI in ATA4, ACS or ACS3.
0xE1 WIN_IDLEIMMDIATE Not part of ATAPI in ATA4, ACS or ACS3.
0xE2 WIN_STANDBY Not part of ATAPI in ATA4, ACS or ACS3.
0xE3 WIN_SETIDLE1 Not part of ATAPI in ATA4, ACS or ACS3.
0xE4 WIN_CHECKPOWERMODE1 Not part of ATAPI in ATA4, ACS or ACS3.
0xE5 WIN_SLEEPNOW1 Not part of ATAPI in ATA4, ACS or ACS3.
0xF8 WIN_READ_NATIVE_MAX Obsoleted in ACS3. Not ATAPI in ATA4 or ACS.
This patch fixes a divide by zero fault that can be caused by sending
the WIN_READ_NATIVE_MAX command to an ATAPI drive, which causes it to
attempt to use zeroed CHS values to perform sector arithmetic.

target-arm: Share all common TCG temporaries
This is a bug fix for aarch64. At present, we have branches using
the 32-bit (translate.c) versions of cpu_[NZCV]F, but we set the flags
using the 64-bit (translate-a64.c) versions of cpu_[NZCV]F. From
the view of the TCG code generator, these are unrelated variables.
The bug is hard to see because we currently only read these variables
from branches, and upon reaching a branch TCG will first spill live
variables and then reload the arguments of the branch. Since the
32-bit versions were never live until reaching the branch, we'd re-read
the data that had just been spilled from the 64-bit versions.
There is currently no such problem with the cpu_exclusive_* variables,
but there's no point in tempting fate.

When QEMU starts the RCU thread executes qemu_mutex_lock_thread
causing error "qemu:qemu_cpu_kick_thread: No such process" and exits.
This isn't occur frequently but in glibc the thread id can exist and
this not guarantee that the thread is on active/running state. If is
inserted a sleep(1) after newthread assignment [1] the issue appears.
So not make assumption that thread exist if first_cpu->thread is set
then change the validation of cpu to created that is set into cpu
threads (kvm, tcg, dummy).

rtl8139: Fix receive buffer overflow check
rtl8139_do_receive() tries to check for the overflow condition
by making sure that packet_size + 8 does not exceed the
available buffer space. The issue here is that RxBuffAddr,
used to calculate available buffer space, is aligned to a
a 4 byte boundry after every update. So it is possible that
every packet ends up being slightly padded when written
to the receive buffer. This padding is not taken into
account when checking for overflow and we may end up missing
the overflow condition can causing buffer overwrite.
This patch takes alignment into consideration when
checking for overflow condition.

s390x/css: start with cleared cstat/dstat
When executing the start function, we should start with a clear state
regarding subchannel and device status; it is easy to forget updating one
of them after the ccw has been processed.
Note that we don't need to care about resetting the various control
fields: They are cleared by tsch(), and if they were still pending,
we wouldn't be able to execute the start function in the first
place.
Also note that we don't want to clear cstat/dstat if a suspended
subchannel is resumed.
This fixes a bug where we would continue to present channel-program
check in cstat even though later ccw requests for the subchannel
finished without error (i.e. cstat should be 0).

PPC: E500: Update u-boot to commit 79c884d7e4
The current U-Boot binary in QEMU has a bug where it fails to support
dynamic CCSR addressing. Without this support, u-boot can not boot the
ppce500 machine anymore. This has been fixed upstream in u-boot commit
e834975b.
Update the u-boot blob we carry in QEMU to the latest u-boot upstream,
so that we can successfully run u-boot with the ppce500 machine again.

mac_dbdma: always clear FLUSH bit once DBDMA channel flush is complete
The code to flush the DBDMA channel was effectively duplicated in
dbdma_control_write(), except for the fact that the copy executed outside of a
RUN bit transition was broken by not clearing the FLUSH bit once the flush was
complete.
Newer PPC Linux kernels would timeout waiting for the FLUSH bit to clear again
after submitting a FLUSH command. Fix this by always clearing the FLUSH bit
once the channel flush is complete and removing the repeated code.

mirror: Fix coroutine reentrance
This fixes a regression introduced by commit dcfb3beb ("mirror: Do zero
write on target if sectors not allocated"), which was reported to cause
aborts with the message "Co-routine re-entered recursively".
The cause for this bug is the following code in mirror_iteration_done():
if (s->common.busy) {
qemu_coroutine_enter(s->common.co, NULL);
}
This has always been ugly because - unlike most places that reenter - it
doesn't have a specific yield that it pairs with, but is more
uncontrolled. What we really mean here is "reenter the coroutine if
it's in one of the four explicit yields in mirror.c".
This used to be equivalent with s->common.busy because neither
mirror_run() nor mirror_iteration() call any function that could yield.
However since commit dcfb3beb this doesn't hold true any more:
bdrv_get_block_status_above() can yield.
So what happens is that bdrv_get_block_status_above() wants to take a
lock that is already held, so it adds itself to the queue of waiting
coroutines and yields. Instead of being woken up by the unlock function,
however, it gets woken up by mirror_iteration_done(), which is obviously
wrong.
In most cases the code actually happens to cope fairly well with such
cases, but in this specific case, the unlock must already have scheduled
the coroutine for wakeup when mirror_iteration_done() reentered it. And
then the coroutine happened to process the scheduled restarts and tried
to reenter itself recursively.
This patch fixes the problem by pairing the reenter in
mirror_iteration_done() with specific yields instead of abusing
s->common.busy.

vnc: fix memory corruption (CVE-2015-5225)
The _cmp_bytes variable added by commit "bea60dd ui/vnc: fix potential
memory corruption issues" can become negative. Result is (possibly
exploitable) memory corruption. Reason for that is it uses the stride
instead of bytes per scanline to apply limits.
For the server surface is is actually fine. vnc creates that itself,
there is never any padding and thus scanline length always equals stride.
For the guest surface scanline length and stride are typically identical
too, but it doesn't has to be that way. So add and use a new variable
(guest_ll) for the guest scanline length. Also rename min_stride to
line_bytes to make more clear what it actually is. Finally sprinkle
in an assert() to make sure we never use a negative _cmp_bytes again.

block: don't register quorum driver if SHA256 support is unavailable
Commit 488981a4 [block: convert quorum blockdrv to use crypto APIs]
broke qemu-iotest 041 on hosts with GnuTLS < 2.10.0. It converted a
compile-time check to a run-time check at device open time. The result
is that we now advertise a feature (the quorum block driver) that will
never work (on those hosts). There's no way (short of parsing
human-readable error messages) for qemu-iotests or any other API
consumer to recognise that the quorum block driver isn't _actually_
available and shouldn't be used or tested.
Move the run-time check to bdrv_quorum_init() to avoid registering the
quorum block driver if we know it cannot work. This way API consumers
can recognise it's unavailable.

target-mips: Copy restrictions from ext/ins to dext/dins
The checks in dins is required to avoid triggering an assertion
in tcg_gen_deposit_tl. The check in dext is just for completeness.
Fold the other D cases in via fallthru.
In this case the errant dins appears to be data, not code, as
translation failed to stop after a break insn.

This fix migration from the same QEMU version and from previous QEMU
version.
>From the global state section, we don't need runstate with Xen. Right now,
the way the Xen toolstack knows when QEMU is ready is when QEMU reach
"running" runstate.
The configuration section and the section footers are not going to be
present in previous version of QEMU with xenfv machine, so we skip them.
The Xen toolstack libxenlight does not specify a particular version of the
'pc' machine, so migration from older version of QEMU used by Xen to newer
one would break due to missing "configuration" section and section footers.

migration: Fix global state with Xen.
When doing migration via the QMP command xen_save_devices_state, the
current runstate is not store into the global state section. Also the
current runstate is not the one we want on the receiver side.
During migration, the Xen toolstack paused QEMU before save the devices
state. Also, the toolstack expect QEMU to autostart when the migration is
finished.
So this patch store "running" as it's current runstate.

rtl8139: avoid nested ifs in IP header parsing (CVE-2015-5165)
Transmit offload needs to parse packet headers. If header fields have
unexpected values the offload processing is skipped.
The code currently uses nested ifs because there is relatively little
input validation. The next patches will add missing input validation
and a goto label is more appropriate to avoid deep if statement nesting.

tcg/mips: fix add2
The add2 code in the tcg_out_addsub2 function doesn't take into account
the case where rl == al == bl. In that case we can't compute the carry
after the addition. As it corresponds to a multiplication by 2, the
carry bit is the bit 31.
While this is a corner case, this prevents x86-64 guests to boot on a
MIPS host.

AioContext: avoid leaking BHs on cleanup
virtio-blk-dataplane: delete bottom half before the AioContext is freed

AioContext: force event loop iteration using BH
The notify_me optimization introduced in commit eabc97797310
("AioContext: fix broken ctx->dispatching optimization") skips
event_notifier_set() calls when the event loop thread is not blocked in
ppoll(2).
This optimization causes a deadlock if two aio_context_acquire() calls
race. notify_me = 0 during the race so the winning thread can enter
ppoll(2) unaware that the other thread is waiting its turn to acquire
the AioContext.
This patch forces ppoll(2) to return by scheduling a BH instead of
calling aio_notify().
The following deadlock with virtio-blk dataplane is fixed:
qemu ... -object iothread,id=iothread0 \
-drive if=none,id=drive0,file=test.img,... \
-device virtio-blk-pci,iothread=iothread0,drive=drive0
This command-line results in a hang early on without this patch.

AioContext: avoid leaking BHs on cleanup
BHs are freed during aio_bh_poll(). This leads to memory leaks if there
is no aio_bh_poll() between qemu_bh_delete() and aio_ctx_finalize().

Other uses of aio_bh_new are safe as long as all scheduled bottom

hw/net: handle flow control in mcf_fec driver receiver
The network mcf_fec driver emulated receive side method is not dealing
with network queue flow control properly.
Modify the receive side to check if we have enough space in the
descriptors to store the current packet. If not we process none of it
and return 0. When the guest frees up some buffers through its descriptors
we signal the qemu net layer to send more packets.

block/ssh: Avoid segfault if inet_connect doesn't set errno.
On some (but not all) systems:
$ qemu-img create -f qcow2 overlay -b ssh://xen/
Segmentation fault
It turns out this happens when inet_connect returns -1 in the
following code, but errno == 0.
s->sock = inet_connect(s->hostport, errp);
if (s->sock < 0) {
ret = -errno;
goto err;
}
In the test case above, no host called "xen" exists, so getaddrinfo fails.
On Fedora 22, getaddrinfo happens to set errno = ENOENT (although it
is *not* documented to do that), so it doesn't segfault.
On RHEL 7, errno is not set by the failing getaddrinfo, so ret =
-errno = 0, so the caller doesn't know there was an error and
continues with a half-initialized BDRVSSHState struct, and everything
goes south from there, eventually resulting in a segfault.
Fix this by setting ret to -EIO (same as block/nbd.c and
block/sheepdog.c). The real error is saved in the Error** errp
struct, so it is printed correctly:
$ ./qemu-img create -f qcow2 overlay -b ssh://xen/
qemu-img: overlay: address resolution failed for xen:22: No address associated with hostname

sheepdog: serialize requests to overwrapping area
Current sheepdog driver only serializes create requests in oid
unit. This mechanism isn't enough for handling requests to
overwrapping area spanning multiple oids, so it can result bugs like
below:
https://bugs.launchpad.net/sheepdog-project/+bug/1456421
This patch adds a new serialization mechanism for the problem. The
difference from the old one is:
1. serialize entire aiocb if their targetting areas overwrap
2. serialize all requests (read, write, and discard), not only creates
This patch also removes the old mechanism because the new one can be
an alternative.

memory: do not add a reference to the owner of aliased regions
Very often the owner of the aliased region is the same as the owner of the alias
region itself. When this happens, the reference count can never go back to 0 and
the owner is leaked. This is for example breaking hot-unplug of virtio-pci
devices (the device cannot be plugged back again with the same id).
Another common use for alias is to transform the system I/O address space
into an MMIO regions; in this case the aliased region never dies, so there
is no problem. Otherwise the owner is always the same for aliasing
and aliased region.
I checked all calls to memory_region_init_alias introduced after commit
dfde4e6 (memory: add ref/unref calls, 2013-05-06) and they do not need the
reference in order to keep the owner of the aliased region alive.

megasas: Add write function to handle write access to PCI BAR 3
This patch fixes a QEMU SEGFAULT when a write operation is performed on
the memory region of the PCI BAR 3 (base address space).
When a writeb(0xe0000000) is performed the .write function is invoked to
handle the write access, however, since the .write is not initialised,
the call to 0, causes QEMU to SEGFAULT.

main-loop: fix qemu_notify_event for aio_notify optimization
aio_notify can be optimized away, and in fact almost always will. However,
qemu_notify_event is used in places where this is incorrect---most notably,
when handling SIGTERM. When aio_notify is optimized away, it is possible that
QEMU enters a blocking ppoll immediately afterwards and stays there, without
reaching main_loop_should_exit().
Fix this by using a bottom half. The bottom half can be optimized too, but
scheduling it is enough for the ppoll not to block. The hang is thus avoided.

This checks that VPC is able to successfully fail (without segfault)

Date: Fri Jul 24 10:26:51 2015 -0400
block: vpc - prevent overflow if max_table_entries >= 0x40000000
When we allocate the pagetable based on max_table_entries, we multiply
the max table entry value by 4 to accomodate a table of 32-bit integers.
However, max_table_entries is a uint32_t, and the VPC driver accepts
ranges for that entry over 0x40000000. So during this allocation:
s->pagetable = qemu_try_blockalign(bs->file, s->max_table_entries * 4);
The size arg overflows, allocating significantly less memory than
expected.
Since qemu_try_blockalign() size argument is size_t, cast the
multiplication correctly to prevent overflow.
The value of "max_table_entries * 4" is used elsewhere in the code as
well, so store the correct value for use in all those cases.
We also check the Max Tables Entries value, to make sure that it is <
SIZE_MAX / 4, so we know the pagetable size will fit in size_t.

axienet: Flush queued packets when rx is done
eth_can_rx checks s->rxsize and returns false if it is non-zero. Because
of the .can_receive semantics change, this will make the incoming queue
disabled by peer, until it is explicitly flushed. So we should flush it
when s->rxsize is becoming zero.
Squash eth_can_rx semantics into etx_rx and drop .can_receive()
callback, also add flush when rx buffer becomes available again after a
packet gets queued.
The other conditions, "!axienet_rx_resetting(s) &&
axienet_rx_enabled(s)" are OK because enet_write already calls
qemu_flush_queued_packets when the register bits are changed.

hw/net: fix mcf_fec driver receiver
The network mcf_fec driver emulated receive side method is returning a
result of 0 causing the network layer to disable receive for this emulated
device. This results in the guest only ever receiving one packet.
Fix the recieve side processing to return the number of bytes that we
passed back through to the guest.

hw/net: add simple phy support to mcf_fec driver
The Linux fec driver needs at least basic phy support to probe and work.
The current qemu mcf_fec emulation has no support for the reading or
writing of the MDIO lines to access an attached phy.
This code adds a very simple set of register results for a fixed phy
setup - very similar to that used on an m5208evb board. This is enough
to probe and identify an emulated attached phy.

crypto: extend unit tests to cover decryption too
The current unit test only verifies the encryption API,
resulting in us missing a recently introduced bug in the
decryption API from commit d3462e3. It was fortunately
later discovered & fixed by commit bd09594, thanks to the
QEMU I/O tests for qcow2 encryption, but we should really
detect this directly in the crypto unit tests. Also remove
an accidental debug message and simplify some asserts.

ide: Check array bounds before writing to io_buffer (CVE-2015-5154)
If the end_transfer_func of a command is called because enough data has
been read or written for the current PIO transfer, and it fails to
correctly call the command completion functions, the DRQ bit in the
status register and s->end_transfer_func may remain set. This allows the
guest to access further bytes in s->io_buffer beyond s->data_end, and
eventually overflowing the io_buffer.
One case where this currently happens is emulation of the ATAPI command
START STOP UNIT.
This patch fixes the problem by adding explicit array bounds checks
before accessing the buffer instead of relying on end_transfer_func to
function correctly.

framebuffer: set DIRTY_MEMORY_VGA on RAM that is used for the framebuffer
The MemoryRegionSection contains enough information to access the
RAM region underlying the framebuffer, and can be cached inside the
display device.
By doing this, the new framebuffer_update_memory_section function can
enable dirty memory logging on the relevant RAM region. The function
must be called whenever the stride or base of the framebuffer changes;
a simple way to cover these cases is to call it on every full frame
invalidation, which is a rare case.
framebuffer_update_display now works entirely on a MemoryRegionSection,
without going through cpu_physical_memory_map/unmap.

scsi: Handle no media case for scsi_get_configuration
Currently, scsi_get_configuration always returns a current
profile (DVD or CD), even when there is actually no media present.
By comparison, ide/atapi uses a default profile of 0 (MMC_PROFILE_NONE)
for this case and checks for tray_open, so let's do the same for scsi.
This fixes a problem I'm seeing with Fedora 22 guests where systemd
cdrom_id fails to unmount after a QEMU-initiated eject against a
scsi cdrom device because it believes the media is still present
(but unreadable).

qemu-char: Fix missed data on unix socket
Commit 812c1057 introduced HUP detection on unix and tcp sockets prior
to a read in tcp_chr_read. This unfortunately broke CloudStack 4.2
which relied on the old behaviour where data on a socket was readable
even if a HUP was present.
A working solution is to properly check the return values from recv,
handling a closed socket once there is no more data to read.
Also enable polling for G_IO_NVAL to ensure the callback is called
for all possible events as these should now be possible to handle
with the improved error detection.

vfio/pci: Fix RTL8168 NIC quirks
The RTL8168 quirk correctly describes using bit 31 as a signal to
mark a latch/completion, but the code mistakenly uses bit 28. This
causes the Realtek driver to spin on this register for quite a while,
20k cycles on Windows 7 v7.092 driver. Then it gets frustrated and
tries to set the bit itself and spins for another 20k cycles. For
some this still results in a working driver, for others not. About
the only thing the code really does in its current form is protect
the guest from sneaking in writes to the real hardware MSI-X table.
The fix is obviously to use bit 31 as we document that we should.
The other problem doesn't seem to affect current drivers as nobody
seems to use these window registers for writes to the MSI-X table, but
we need to use the stored data when a write is triggered, not the
value of the current write, which only provides the offset.
Note that only the Windows drivers from Realtek seem to use these
registers, the Microsoft drivers provided with Windows 8.1 do not
access them, nor do Linux in-kernel drivers.

AioContext: optimize clearing the EventNotifier
It is pretty rare for aio_notify to actually set the EventNotifier. It
can happen with worker threads such as thread-pool.c's, but otherwise it
should never be set thanks to the ctx->notify_me optimization. The
previous patch, unfortunately, added an unconditional call to
event_notifier_test_and_clear; now add a userspace fast path that
avoids the call.
Note that it is not possible to do the same with event_notifier_set;
it would break, as proved (again) by the included formal model.
This patch survived over 3000 reboots on aarch64 KVM.

AioContext: fix broken placement of event_notifier_test_and_clear
event_notifier_test_and_clear must be called before processing events.
Otherwise, an aio_poll could "eat" the notification before the main
I/O thread invokes ppoll(). The main I/O thread then never wakes up.
This is an example of what could happen:
i/o thread vcpu thread worker thread
---------------------------------------------------------------------
lock_iothread
notify_me = 1
...
unlock_iothread
bh->scheduled = 1
event_notifier_set
lock_iothread
notify_me = 3
ppoll
notify_me = 1
aio_dispatch
aio_bh_poll
thread_pool_completion_bh
bh->scheduled = 1
event_notifier_set
node->io_read(node->opaque)
event_notifier_test_and_clear
ppoll
*** hang ***
"Tracing" with qemu_clock_get_ns shows pretty much the same behavior as
in the previous bug, so there are no new tricks here---just stare more
at the code until it is apparent.
One could also use a formal model, of course. The included one shows
this with three processes: notifier corresponds to a QEMU thread pool
worker, temporary_waiter to a VCPU thread that invokes aio_poll(),
waiter to the main I/O thread. I would be happy to say that the
formal model found the bug for me, but actually I wrote it after the
fact.
This patch is a bit of a big hammer. The next one optimizes it,
with help (this time for real rather than a posteriori :)) from
another, similar formal model.

AioContext: fix broken ctx->dispatching optimization
This patch rewrites the ctx->dispatching optimization, which was the cause
of some mysterious hangs that could be reproduced on aarch64 KVM only.
The hangs were indirectly caused by aio_poll() and in particular by
flash memory updates's call to blk_write(), which invokes aio_poll().
Fun stuff: they had an extremely short race window, so much that
adding all kind of tracing to either the kernel or QEMU made it
go away (a single printf made it half as reproducible).
On the plus side, the failure mode (a hang until the next keypress)
made it very easy to examine the state of the process with a debugger.
And there was a very nice reproducer from Laszlo, which failed pretty
often (more than half of the time) on any version of QEMU with a non-debug
kernel; it also failed fast, while still in the firmware. So, it could
have been worse.
For some unknown reason they happened only with virtio-scsi, but
that's not important. It's more interesting that they disappeared with
io=native, making thread-pool.c a likely suspect for where the bug arose.
thread-pool.c is also one of the few places which use bottom halves
across threads, by the way.
I hope that no other similar bugs exist, but just in case :) I am
going to describe how the successful debugging went... Since the
likely culprit was the ctx->dispatching optimization, which mostly
affects bottom halves, the first observation was that there are two
qemu_bh_schedule() invocations in the thread pool: the one in the aio
worker and the one in thread_pool_completion_bh. The latter always
causes the optimization to trigger, the former may or may not. In
order to restrict the possibilities, I introduced new functions
qemu_bh_schedule_slow() and qemu_bh_schedule_fast():
/* qemu_bh_schedule_slow: */
ctx = bh->ctx;
bh->idle = 0;
if (atomic_xchg(&bh->scheduled, 1) == 0) {
event_notifier_set(&ctx->notifier);
}
/* qemu_bh_schedule_fast: */
ctx = bh->ctx;
bh->idle = 0;
assert(ctx->dispatching);
atomic_xchg(&bh->scheduled, 1);
Notice how the atomic_xchg is still in qemu_bh_schedule_slow(). This
was already debated a few months ago, so I assumed it to be correct.
In retrospect this was a very good idea, as you'll see later.
Changing thread_pool_completion_bh() to qemu_bh_schedule_fast() didn't
trigger the assertion (as expected). Changing the worker's invocation
to qemu_bh_schedule_slow() didn't hide the bug (another assumption
which luckily held). This already limited heavily the amount of
interaction between the threads, hinting that the problematic events
must have triggered around thread_pool_completion_bh().
As mentioned early, invoking a debugger to examine the state of a
hung process was pretty easy; the iothread was always waiting on a
poll(..., -1) system call. Infinite timeouts are much rarer on x86,
and this could be the reason why the bug was never observed there.
With the buggy sequence more or less resolved to an interaction between
thread_pool_completion_bh() and poll(..., -1), my "tracing" strategy was
to just add a few qemu_clock_get_ns(QEMU_CLOCK_REALTIME) calls, hoping
that the ordering of aio_ctx_prepare(), aio_ctx_dispatch, poll() and
qemu_bh_schedule_fast() would provide some hint. The output was:
(gdb) p last_prepare
$3 = 103885451
(gdb) p last_dispatch
$4 = 103876492
(gdb) p last_poll
$5 = 115909333
(gdb) p last_schedule
$6 = 115925212
Notice how the last call to qemu_poll_ns() came after aio_ctx_dispatch().
This makes little sense unless there is an aio_poll() call involved,
and indeed with a slightly different instrumentation you can see that
there is one:
(gdb) p last_prepare
$3 = 107569679
(gdb) p last_dispatch
$4 = 107561600
(gdb) p last_aio_poll
$5 = 110671400
(gdb) p last_schedule
$6 = 110698917
So the scenario becomes clearer:
iothread VCPU thread
--------------------------------------------------------------------------
aio_ctx_prepare
aio_ctx_check
qemu_poll_ns(timeout=-1)
aio_poll
aio_dispatch
thread_pool_completion_bh
qemu_bh_schedule()
At this point bh->scheduled = 1 and the iothread has not been woken up.
The solution must be close, but this alone should not be a problem,
because the bottom half is only rescheduled to account for rare situations
(see commit 3c80ca1, thread-pool: avoid deadlock in nested aio_poll()
calls, 2014-07-15).
Introducing a third thread---a thread pool worker thread, which
also does qemu_bh_schedule()---does bring out the problematic case.
The third thread must be awakened *after* the callback is complete and
thread_pool_completion_bh has redone the whole loop, explaining the
short race window. And then this is what happens:
thread pool worker
--------------------------------------------------------------------------
<I/O completes>
qemu_bh_schedule()
Tada, bh->scheduled is already 1, so qemu_bh_schedule() does nothing
and the iothread is never woken up. This is where the bh->scheduled
optimization comes into play---it is correct, but removing it would
have masked the bug.
So, what is the bug?
Well, the question asked by the ctx->dispatching optimization ("is any
active aio_poll dispatching?") was wrong. The right question to ask
instead is "is any active aio_poll *not* dispatching", i.e. in the prepare
or poll phases? In that case, the aio_poll is sleeping or might go to
sleep anytime soon, and the EventNotifier must be invoked to wake
it up.
In any other case (including if there is *no* active aio_poll at all!)
we can just wait for the next prepare phase to pick up the event (e.g. a
bottom half); the prepare phase will avoid the blocking and service the
bottom half.
Expressing the invariant with a logic formula, the broken one looked like:
!(exists(thread): in_dispatching(thread)) => !optimize
or equivalently:
!(exists(thread):
in_aio_poll(thread) && in_dispatching(thread)) => !optimize
In the correct one, the negation is in a slightly different place:
(exists(thread):
in_aio_poll(thread) && !in_dispatching(thread)) => !optimize
or equivalently:
(exists(thread): in_prepare_or_poll(thread)) => !optimize
Even if the difference boils down to moving an exclamation mark :)
the implementation is quite different. However, I think the new
one is simpler to understand.
In the old implementation, the "exists" was implemented with a boolean
value. This didn't really support well the case of multiple concurrent
event loops, but I thought that this was okay: aio_poll holds the
AioContext lock so there cannot be concurrent aio_poll invocations, and
I was just considering nested event loops. However, aio_poll _could_
indeed be concurrent with the GSource. This is why I came up with the
wrong invariant.
In the new implementation, "exists" is computed simply by counting how many
threads are in the prepare or poll phases. There are some interesting
points to consider, but the gist of the idea remains:
1) AioContext can be used through GSource as well; as mentioned in the
patch, bit 0 of the counter is reserved for the GSource.
2) the counter need not be updated for a non-blocking aio_poll, because
it won't sleep forever anyway. This is just a matter of checking
the "blocking" variable. This requires some changes to the win32
implementation, but is otherwise not too complicated.
3) as mentioned above, the new implementation will not call aio_notify
when there is *no* active aio_poll at all. The tests have to be
adjusted for this change. The calls to aio_notify in async.c are fine;
they only want to kick aio_poll out of a blocking wait, but need not
do anything if aio_poll is not running.
4) nested aio_poll: these just work with the new implementation; when
a nested event loop is invoked, the outer event loop is never in the
prepare or poll phases. The outer event loop thus has already decremented
the counter.

Preparatory bugfixes and tweaks to the loop before the next patch:
- disable dispatch optimization during aio_prepare. This fixes a bug.
- do not modify "blocking" until after the first WaitForMultipleObjects
call. This is needed in the next patch.
- change the loop to do...while. This makes it obvious that the loop
is always entered at least once. In the next patch this is important
because the first iteration undoes the ctx->notify_me increment that
happened before entering the loop.

Limiting to sectors_per_chunk for each bdrv_is_allocated_above is slow,
because the underlying protocol driver would issue much more queries
than necessary. We should coalesce the query.

target-arm: kvm: Differentiate registers based on write-back levels
Some registers like the CNTVCT register should only be written to the
kernel as part of machine initialization or on vmload operations, but
never during runtime, as this can potentially make time go backwards or
create inconsistent time observations between VCPUs.
Introduce a list of registers that should not be written back at runtime
and check this list on syncing the register state to the KVM state.

net: Flush queued packets when guest resumes
Since commit 6e99c63 "net/socket: Drop net_socket_can_send" and friends,
net queues need to be explicitly flushed after qemu_can_send_packet()
returns false, because the netdev side will disable the polling of fd.
This fixes the case of "cont" after "stop" (or migration).

net/vmxnet3: Fix RX TCP/UDP checksum on partially summed packets
Convert partially summed packets to be fully checksummed.
In case csum offloaded packet, vmxnet3 implementation always passes an
RxCompDesc with the "Checksum calculated and found correct" notification
to the OS. This emulates the observed ESXi behavior.
Therefore, if packet has the NEEDS_CSUM bit set, we must calculate and
place a fully computed checksum into the tcp/udp header. Otherwise, the
OS driver will receive a checksum-correct indication but with the actual
tcp/udp checksum field having just the pseudo header csum value.
If host OS performs forwarding, it will forward an incorrectly
checksummed packet.

NANOSECONDS_PER_SECOND to NSEC_PER_SEC.
On Mac OS X there is a <dispatch/time.h> system header which also

virtio-net: Flush incoming queues when DRIVER_OK is being set
This patch fixes network hang after "stop" then "cont", while network
packets keep arriving.
Tested both manually (tap, host pinging guest) and with Jason's qtest
series (plus his "[PATCH 2.4] socket: pass correct size in
net_socket_send()" fix).
As virtio_net_set_status is called when guest driver is setting status
byte and when vm state is changing, it is a good opportunity to flush
queued packets.
This is necessary because during vm stop the backend (e.g. tap) would
stop rx processing after .can_receive returns false, until the queue is
explicitly flushed or purged.
The other interesting condition in .can_receive, virtio_queue_ready(),
is handled by virtio_net_handle_rx() when guest kicks; the 3rd condition
is invalid queue index which doesn't need flushing.

virtio-rng: trigger timer only when guest requests for entropy
This patch triggers timer only when guest requests for
entropy. As soon as first request from guest for entropy
comes we set the timer. Timer bumps up the quota value
when it gets triggered.

crypto: avoid undefined behavior in nettle calls
Calling a function pointer that was cast from an incompatible function
results in undefined behavior. 'void *' isn't compatible with 'struct
XXX *', so we can't cast to nettle_cipher_func, but have to provide a
wrapper. (Conversion from 'void *' to 'struct XXX *' might require
computation, which won't be done if we drop argument's true type, and
pointers can have different sizes so passing arguments on stack would
bug.)
Having two different prototypes based on nettle version doesn't make
this solution any nicer.

memory: fix refcount leak in memory_region_present
memory_region_present() leaks a reference to a MemoryRegion in the
case "mr == container". While fixing it, avoid reference counting
altogether for memory_region_present(), by using RCU only.
The return value could in principle be already invalid immediately
after memory_region_present returns, but presumably the caller knows
that and it's using memory_region_present to probe for devices that
are unpluggable, or something like that. The RCU critical section
is needed anyway, because it protects as->current_map.

qxl: allow to specify head limit to qxl driver
This patch allow to limit number of heads using qxl driver. By default
qxl driver is not limited on any kind on head use so can decide to use
as much heads.
libvirt has this as a video card parameter (actually set to 1 but not
used). This parameter will allow to limit setting a use can do (which
could be confusing).

target-i386: emulate CPUID level of real hardware
W10 insider has a bug where it ignores CPUID level and interprets
CPUID.(EAX=07H, ECX=0H) incorrectly, because CPUID in fact returned
CPUID.(EAX=04H, ECX=0H); this resulted in execution of unsupported
instructions.
While it's a Windows bug, there is no reason to emulate incorrect level.
I used http://instlatx64.atw.hu/ as a source of CPUID and checked that
it matches Penryn Xeon X5472, Westmere Xeon W3520, SandyBridge i5-2540M,
and Haswell i5-4670T.
kvm64 and qemu64 were bumped to 0xD to allow all available features for
them (and to avoid the same Windows bug).

hw/arm/boot: Increase fdt alignment
The Linux kernel on aarch64 creates a page table entry at early bootup
that spans the 2MB range on memory spanning the fdt start address:
[ ALIGN_DOWN(fdt, 2MB) ... ALIGN_DOWN(fdt, 2MB) + 2MB ]
This means that when our current 4k alignment happens to fall at the end
of the aligned region, Linux tries to access memory that is not mapped.
The easy fix is to instead increase the alignment to 2MB, making Linux's
logic always succeed.
We leave the existing 4k alignment for 32bit kernels to not cause any
regressions due to space constraints.

target-arm: Fix broken SCTLR_EL3 reset
The SCTLR_EL3 cpreg definition was implicitly resetting the
register state to 0, which is both wrong and clashes with
the reset done via the SCTLR definition (since sctlr[3]
is unioned with sctlr_s). This went unnoticed until recently,
when an unrelated change (commit a903c449b41f105aa) happened to
perturb the order of enumeration through the cpregs hashtable for
reset such that the erroneous reset happened after the correct one
rather than before it. Fix this by marking SCTLR_EL3 as an alias,
so its reset is left up to the AArch32 view.

target-mips: fix page fault address for LWL/LWR/LDL/LDR
When a LWL, LWR, LDL or LDR instruction triggers a page fault, QEMU
currently reports the aligned address in CP0 BadVAddr, while the Windows
NT kernel expects the unaligned address.
This patch adds a byte access with the unaligned address at the
beginning of the LWL/LWR/LDL/LDR instructions to possibly trigger a page
fault and fill the QEMU TLB.

linux-user: Fix MIPS N64 trap and break instruction bug
For the MIPS N64 ABI when QEMU reads the break/trap instruction so that
it can inspect the break/trap code it reads 8 rather than 4 bytes
which means it finds the code field from the instruction after the
break/trap instruction. This then causes the break/trap handling
code to fail because it does not understand the code number.
The fix forces QEMU to always read 4 bytes of instruction data rather
than deciding how much to read based on the ABI.

migration: We also want to store the global state for savevm
Commit df4b1024526cae3479da3492d6371fd4a7324a03 introduced global_state
section. But it only filled the state while doing migration. While
doing a savevm, we stored an empty string as state. So when we did a
loadvm, it complained that state was invalid.

block/curl: Don't lose original error when a connection fails.
Currently if qemu is connected to a curl source (eg. web server), and
the web server fails / times out / dies, you always see a bogus EIO
"Input/output error".
For example, choose a large file located on any local webserver which
you control:
$ qemu-img convert -p http://example.com/large.iso /tmp/test
Once it starts copying the file, stop the webserver and you will see
qemu-img fail with:
qemu-img: error while reading sector 61440: Input/output error
This patch does two things: Firstly print the actual error from curl
so it doesn't get lost. Secondly, change EIO to EPROTO. EPROTO is a
POSIX.1 compatible errno which more accurately reflects that there was
a protocol error, rather than some kind of hardware failure.
After this patch is applied, the error changes to:
$ qemu-img convert -p http://example.com/large.iso /tmp/test
qemu-img: curl: transfer closed with 469989 bytes remaining to read
qemu-img: error while reading sector 16384: Protocol error

rbd: make qemu's cache setting override any ceph setting
To be safe, when cache=none is used ceph settings should not be able
to override it to turn on caching. This was previously possible with
rbd_cache=true in the rbd device configuration or a ceph configuration
file. Similarly, rbd settings could have turned off caching when qemu
requested it, although this would just be a performance problem.
Fix this by changing rbd's cache setting to match qemu after all other
ceph settings have been applied.

block: Fix backing file child when modifying graph
This patch moves bdrv_attach_child() from the individual places that add
a backing file to a BDS to bdrv_set_backing_hd(), which is called by all
of them. It also adds bdrv_detach_child() there.
For normal operation (starting with one backing file chain and not
changing it until the topmost image is closed) and live snapshots, this
constitutes no change in behaviour.
For all other cases, this is a fix for the bug that the old backing file
was still referenced as a child, and the new one wasn't referenced.

block: Reorder cleanups in bdrv_close()
Block drivers may still want to access their child nodes in their
.bdrv_close handler. If they unref and/or detach a child by themselves,
this should not result in a double free.
There is additional code for backing files, which are just a special
case of child nodes. The same applies for them.

block: Introduce bdrv_open_child()
It is the same as bdrv_open_image(), except that it doesn't only return
success or failure, but the newly created BdrvChild object for the new
child node.
As the BdrvChild object already contains a BlockDriverState pointer (and
this is supposed to become the only pointer so that bdrv_append() and
friends can just change a single pointer in BdrvChild), the pbs
parameter is removed for bdrv_open_child().

pc: fix reuse of pc-i440fx-2.4 in pc-i440fx-2.3
commit fddd179ab962f6f78a8493742e1068d6a620e059,
"pc: Convert *_MACHINE_OPTIONS macros into functions"
broke the chaining of *_machine_options() functions on
pc-i440fx-2.3, at:
-#define PC_I440FX_2_3_MACHINE_OPTIONS \
- PC_I440FX_2_4_MACHINE_OPTIONS, \
- .alias = NULL, \
- .is_default = 0
+static void pc_i440fx_2_3_machine_options(QEMUMachine *m)
+{
+ pc_i440fx_machine_options(m);
+ m->alias = NULL;
+ m->is_default = 0;
+}
I have replaced PC_I440FX_2_4_MACHINE_OPTIONS with a
pc_i440fx_machine_options() call, instead of calling
pc_i440fx_2_4_machine_options(). This broke the setting of default_machine_opts
and default_display on pc-i440fx-{2.0,2,1,2.2,2.3}.
Fix this by making pc_i440fx_2_3_machine_options() reuse
pc_i440fx_2_4_machine_options().

tci: Fix compile failure by including qemu-common.h
Compilation of TCI was accidentally broken by the recent disassembler
changes:

In file included from target-i386/cpu-qom.h:23:0,
from target-i386/cpu.h:986,

from disas/tci.c:20:

^
include/qom/cpu.h:179:1: error:
no semicolon at end of struct or union [-Werror]
} CPUClass;
^
cc1: all warnings being treated as errors
The underlying cause of this is an include loop:
bfd.h -> qemu-common.h -> target-arm/cpu.h -> target-arm/cpu-qom.h
-> qom/cpu.h -> bfd.h
which means that if bfd.h is included first then qom/cpu.h doesn't
get the definition of the disassemble_info type that it wanted.
The easiest fix for this is to include qemu-common.h from tci.c
before including disas/bfd.h.

disas: cris: Fix 0 buffer length case
Cris has the complication of variable length instructions and has
a check in place to clamp memory reads in case the disas request
doesn't have enough bytes for the instruction being disas'd. This
breaks down in the case where disassembling for the monitor where
the buffer length is defaulted to 0.
The buffer length should never be zero for a regular target_disas,
so we can safely assume the 0 case is for the monitor in which case
consider the buffer length to be the max for cris instructions.

Move the target_disas() ARM specifics to the QOM disas_set_info hook

This has the extra advantage of the more fully featured target_disas()

disas: Add print_insn to disassemble info
Add the print_insn pointer to the disassemble info structure. This is
to prepare for QOMification support, where a QOM CPU hook function will
be responsible for setting the print_insn() function. Add this function
to the existing struct to consolidate such that only the one struct
needs to be passed to the new QOM API.

cpu: Convert cpu_index into a bitmap
Currently CPUState::cpu_index is monotonically increasing and a newly
created CPU always gets the next higher index. The next available
index is calculated by counting the existing number of CPUs. This is
fine as long as we only add CPUs, but there are architectures which
are starting to support CPU removal, too. For an architecture like PowerPC
which derives its CPU identifier (device tree ID) from cpu_index, the
existing logic of generating cpu_index values causes problems.
With the currently proposed method of handling vCPU removal by parking
the vCPU fd in QEMU
(Ref: http://lists.gnu.org/archive/html/qemu-devel/2015-02/msg02604.html),
generating cpu_index this way will not work for PowerPC.
This patch changes the way cpu_index is handed out by maintaining
a bit map of the CPUs that tracks both addition and removal of CPUs.
The CPU bitmap allocation logic is part of cpu_exec_init(), which is
called by instance_init routines of various CPU targets. Newly added
cpu_exec_exit() API handles the deallocation part and this routine is
called from generic CPU instance_finalize.
Note: This new CPU enumeration is for !CONFIG_USER_ONLY only.
CONFIG_USER_ONLY continues to have the old enumeration logic.

Add an Error argument to cpu_exec_init() to let users collect the

can fail if cpu_index values corresponding to max_cpus have already

Merge remote-tracking branch 'remotes/mdroth/tags/qga-pull-2015-07-06-v3-tag' into staging
tag for qga-pull-2015-07-06-v3
v3:
- fix missing <windows.h> in configure test program.
v2:
- added configure check for guest-get-fs-info to avoid breakage on older
MinGWs
- removed extraneous include of ws2ipdef.h in w32
guest-network-get-interfaces. ws2tcpip.h already provides those
definitions, and older MinGWs don't have it.
- rebased on latest master

hw/i386/pc: reflect any FDC @ ioport 0x3f0 in the CMOS
With the pc-q35-2.4 machine type, if the user creates an ISA FDC manually:
-device isa-fdc,driveA=drive-fdc0-0-0 \
-drive file=...,if=none,id=drive-fdc0-0-0,format=raw
then the board-default FDC will be skipped, and only the explicitly
requested FDC will exist. qtree-wise, this is correct; however such an FDC
is currently not registered in the CMOS, because that code is only reached
for the board-default FDC.
The pc_cmos_init_late() one-shot reset handler -- one-shot because the
CMOS is not reprogrammed during warm reset -- should search for any ISA
FDC devices, created implicitly (by board code) or explicitly, and set the
CMOS accordingly to the ISA FDC(s) with iobase=0x3f0:
- if there is no such FDC, report both drives absent,
- if there is exactly one such FDC, report its drives in the CMOS,
- if there are more than one such FDCs, then pick one (it is not specified
which one), and print a warning about the ambiguity.

ich9: implement strap SPKR pin logic
If the signal is sampled high, this indicates that the system is
strapped to the "No Reboot" mode (ICH9 will disable the TCO Timer system
reboot feature). The status of this strap is readable via the NO_REBOOT
bit (CC: offset 0x3410:bit 5).
The NO_REBOOT bit is set when SPKR pin on ICH9 is sampled high. This bit
may be set or cleared by software if the strap is sampled low but may
not override the strap when it indicates "No Reboot".
This patch implements the logic where hardware has ability to set SPKR
pin through a property named "noreboot" and it's sampled high by
default.

qga: added GuestPCIAddress information
PCIAddress inforfation is obtained via SetupApi, which provides the
information about address, bus, etc. We look throught entire device tree
in the system and try to find device object for given volume. For this PDO
SetupDiGetDeviceRegistryProperty is called, which reads PCI configuration
for a given devicei if it is possible.
This is the most convinient way for a userspace service. The lookup is
performed for every volume available. However, this information is
not mandatory for vss-provider.
In order to use SetupApi we need to notify linker about it. We do not need
to install additional libs, so we do not make separate configuration
option to use libsetupapi.su
SetupApi gives as the same information as kernel driver
with IRP_MN_QUERY_INTERFACE.

qga: added mountpoint and filesystem type for single volume
We should use GetVolumeXXX api to work with volumes. This will help us to
resolve the situation with volumes without drive letter, i.e. when the
volume is mounted as a folder. Such volume is called mounted folder.
This volume is a regular mounted volume from all other points of view.
The information about non mounted volume is reported as System Reserved.
This volume is not mounted and thus it is not writable.
GuestDiskAddressList API is not used because operations are performed with
volumes but no with disks. This means that spanned disk will
be counted and handled as a single volume. It is worth mentioning
that the information about every disk in the volume can be queried
via IOCTL_VOLUME_GET_VOLUME_DISK_EXTENTS.

qga: win32 qmp_guest_network_get_interfaces implementation
By default, IPv4 prefixes will be derived by matching the address

In Windows Vista/2008 guests and newer, both IPv4 and IPv6 prefixes
can be retrieved from OnLinkPrefixLength. Setting --extra-cflags
in the build configuration to "-D_WIN32_WINNT=0x600"
or greater makes OnLinkPrefixLength available. Setting --extra-cflags
is not required and if not set, the default approach to get the prefix

This reverts commit 8f4774789947bc4bc4c8d026a289fe980d3d2ee1.

qga/qmp_guest_fstrim: Return per path fstrim result
The current guest-fstrim support only returns an error if some
mountpoint was unable to be trimmed, skipping any possible additional
mountpoints. The result of the TRIM operation itself is also discarded.
This change returns a per mountpoint result of the TRIM operation. If an
error occurs on some mountpoints that error is returned and the
guest-fstrim continue with any additional mountpoints.
The returned values for errors, minimum and trimmed are dependant on the
filesystem, storage stacks and kernel version.

qga/commands-posix: Fix bug in guest-fstrim
The FITRIM ioctl updates the fstrim_range structure it receives. This
way the caller can determine how many bytes were trimmed. The
guest-fstrim logic reuses the same fstrim_range for each filesystem,
effectively limiting each filesystem to trim at most as much as the
previous was able to trim.
If a previous filesystem would have trimmed 0 bytes, than the next
filesystem would report an error 'Invalid argument' because a FITRIM
request with length 0 is not valid.
This change resets the fstrim_range structure for each filesystem.

sPAPR: Clear stale MSIx table during EEH reset
The PCI device MSIx table is cleaned out in hardware after EEH PE
reset. However, we still hold the stale MSIx entries in QEMU, which
should be cleared accordingly. Otherwise, we will run into another
(recursive) EEH error and the PCI devices contained in the PE have
to be offlined exceptionally.
The patch introduces function spapr_phb_vfio_eeh_pre_reset(), which
is called by sPAPR when asserting hot or fundamental reset, to clear
stale MSIx table for VFIO PCI devices before EEH PE reset so that
MSIx table could be restored properly after EEH PE reset.

spapr_vty: lookup should only return valid VTY objects
If a guest passes the reg property of a valid VIO object that is not a VTY
to either H_GET_TERM_CHAR or H_PUT_TERM_CHAR, QEMU hits a dynamic cast
assertion and aborts.
PAPR+ says "Hypervisor checks the termno parameter for validity against the
Vterm IOA unit addresses assigned to the partition, else return H_Parameter."
This patch adds a type check to ensure vty_lookup() either returns a pointer
to a valid VTY object or NULL. H_GET_TERM_CHAR and H_PUT_TERM_CHAR will
now return H_PARAMETER to the guest instead of crashing.
The patch has no effect on the reg == 0 hack used to implement the RTAS call
display-character.

spapr_pci: enumerate and add PCI device tree
All the PCI enumeration and device node creation was off-loaded to

hotplug code. To unify this, the patch adds the pci device node
creation in Qemu. For backward compatibility, a flag
"qemu,phb-enumerated" is added to the phb, suggesting to SLOF to not
do device node creation.

xics_kvm: Don't enable KVM_CAP_IRQ_XICS if already enabled
When supporting CPU hot removal by parking the vCPU fd and reusing
it during hotplug again, there can be cases where we try to reenable
KVM_CAP_IRQ_XICS CAP for the vCPU for which it was already enabled.
Introduce a boolean member in ICPState to track this and don't
reenable the CAP if it was already enabled earlier.
Re-enabling this CAP should ideally work, but currently it results in
kernel trying to create and associate ICP with this vCPU and that
fails since there is already an ICP associated with it. Hence this
patch is needed to work around this problem in the kernel.
This change allows CPU hot removal to work for sPAPR.

Revert "hw/ppc/spapr_pci.c: Avoid functions not in glib 2.12 (g_hash_table_iter_*)"
Since we now require GLib 2.22+ (commit f40685c), we don't have to
work around lack of g_hash_table_iter_init() & friends anymore.
This reverts commit f8833a37c0c6b22ddd57b45e48cfb0f97dbd5af4.

The fact that these enums have matching values is pure coincidence. We

spapr: Remove obsolete ram_limit field from sPAPRMachineState
The ram_limit field was imported from sPAPREnvironment where it predates
the machine's ram size being available generically from machine->ram_size.
Worse, the existing code was inconsistent about where it got the ram size
from. Sometimes it used spapr->ram_limit, sometimes the global 'ram_size'
and sometimes a local 'ram_size' masking the global.
This cleans up the code to consistently use machine->ram_size, eliminating
spapr->ram_limit in the process.

spapr: Merge sPAPREnvironment into sPAPRMachineState
The code for -machine pseries maintains a global sPAPREnvironment structure
which keeps track of general state information about the guest platform.
This predates the existence of the MachineState structure, but performs
basically the same function.
Now that we have the generic MachineState, fold sPAPREnvironment into
sPAPRMachineState, the pseries specific subclass of MachineState.
This is mostly a matter of search and replace, although a few places which
relied on the global spapr variable are changed to find the structure via
qdev_get_machine().

spapr: ensure we have at least one XICS server
XICS needs to know the upper value for cpu_index as it is used to compute
the number of servers:
smp_cpus * kvmppc_smt_threads() / smp_threads
When passing -smp cpus=1,threads=9 on a POWER8 host, we end up with:
1 * 8 / 9 = 0
... which leads to an assertion in both emulated:
Number of servers needs to be greater 0
Aborted (core dumped)
... and in-kernel XICS:
xics_kvm_realize: Assertion `icp->nr_servers' failed.
Aborted (core dumped)
With this patch, we are sure that nr_servers > 0. Passing the same bogus
-smp option then leads to:
qemu-system-ppc64: Cannot support more than 8 threads on PPC with KVM
... which is a lot more explicit than the XICS errors.

target-ppc: fix hugepage support when using memory-backend-file
Current PPC code relies on -mem-path being used in order for
hugepage support to be detected. With the introduction of
MemoryBackendFile we can now handle this via:
-object memory-file-backend,mem-path=...,id=hugemem0 \
-numa node,id=mem0,memdev=hugemem0
Management tools like libvirt treat the 2 approaches as
interchangeable in some cases, which can lead to user-visible
regressions even for previously supported guest configurations.
Fix these by also iterating through any configured memory
backends that may be backed by hugepages.
Since the old code assumed hugepages always backed the entirety
of guest memory, play it safe an pick the minimum across the
max pages sizes for all backends, even ones that aren't backed
by hugepages.

macio: remove nonexistent interrupt on pin 1
The current macio implementation declares an interrupt that doesn't appear to
exist in the hardware or any other emulator implementation. OpenBIOS detects
this interrupt and generates an 'interrupts' property in the macio device tree
entry. Mac OS 9 halts boot when it detects this interrupt, so it has been
removed to permit further progress in the boot process.

target-i386: avoid overflow in the tsc-frequency property
The TSC frequency fits comfortably in an int when expressed in kHz,
but it may overflow when converted to Hz. In this case,
tsc-frequency returns a negative value because x86_cpuid_get_tsc_freq
does a 32-bit multiplication before assigning to int64_t.
For simplicity just make tsc_khz a 64-bit value.

block/raw-posix: Don't think /dev/fd/<NN> is a floppy drive.
In libguestfs we use /dev/fd/<NN> to pass pre-opened file descriptors
to qemu-img. Lately I've discovered that although this works, qemu
believes that these are floppy disk images. That in itself isn't much
of a problem, but now qemu prints a warning about host floppy
pass-thru being deprecated.
Extend the existing test so that it ignores /dev/fd/ as well as
/dev/fdset/
A simple test of this, if you are using the bash shell, is:
qemu-img info <( cat /dev/null )
without this patch:
$ qemu-img info <( cat /dev/null )
qemu-img: Host floppy pass-through is deprecated
Support for it will be removed in a future release.

migration: create new section to store global state
This includes a new section that for now just stores the current qemu state.
Right now, there are only one way to control what is the state of the
target after migration.
- If you run the target qemu with -S, it would start stopped.
- If you run the target qemu without -S, it would run just after migration finishes.
The problem here is what happens if we start the target without -S and
there happens one error during migration that puts current state as
-EIO. Migration would ends (notice that the error happend doing block
IO, network IO, i.e. nothing related with migration), and when
migration finish, we would just "continue" running on destination,
probably hanging the guest/corruption data, whatever.

Fail more cleanly in mismatched RAM cases
If the number of RAMBlocks was different on the source from the
destination, QEMU would hang waiting for a disconnect on the source
and wouldn't release from that hang until the destination was manually
killed.
Mark the stream as being in error, this causes the destination to die
and the source to carry on.

Sort destination RAMBlocks to be the same as the source
Use the order of incoming RAMBlocks from the source to record
an index number; that then allows us to sort the destination
local RAMBlock list to match the source.
Now that the RAMBlocks are known to be in the same order, this
simplifies the RDMA Registration step which previously tried to
match RAMBlocks based on offset (which isn't guaranteed to match).
Looking at the existing compress code, I think it was erroneously
relying on an assumption of matching ordering, which this fixes.

Translate offsets to destination address space
The 'offset' field in RDMACompress and 'current_addr' field
in RDMARegister are commented as being offsets within a particular
RAMBlock, however they appear to actually be offsets within the
ram_addr_t space.
The code currently assumes that the offsets on the source/destination
match, this change removes the need for the assumption for these
structures by translating the addresses into the ram_addr_t space of
the destination host.
Note: An alternative would be to change the fields to actually
take the data they're commented for; this would potentially be
simpler but would break stream compatibility for those cases
that currently work.

rocker: mark copy-to-cpu pkts as forwarding offloaded
For pkts copied to the CPU (to be processed by guest driver), mark the Rx
descriptor with flag "OFFLOAD_FWD" to indicate device has already forwarded
pkt. The guest driver will use this indicator to avoid duplicate
forwarding in the guest OS.
Examples include bcast/mcast/unknown ucast pkts flooded to bridged ports.
We want to avoid both the device and the guest bridge driver flooding these
pkts, which would result in duplicates pkts on the wire. Packet sampling,
such as sFlow, can also use this technique to mark pkts for the guest OS to
record but otherwise drop.

rocker: don't queue receive pkts when port is disabled
Commit 6e99c63 ("net/socket: Drop net_socket_can_send") changed the
semantics around .can_receive for sockets to now require the device to
flush queued pkts when transitioning to a .can_receive=true state. Rocker
device was not flushing the queue on .can_receive=true transition, so the
receiver was stuck.
But, turns out we really don't want any queuing at all on the port when the
port is disabled, otherwise when the port transitions to enabled, we'd
receive and forward stale pkts that really should have been dropped. So,
let's remove .can_receive so avoid queuing and drop the pkt in .receive if
the port is disabled.

vmxnet3: Fix incorrect small packet padding
When running ESXi under qemu there is an issue with the ESXi guest
discarding packets that are too short. The guest discards any packets
under the normal minimum length for an ethernet packet (60). This
results in odd behaviour where other hosts or VMs on other hosts can
communicate with the ESXi guest just fine (since there's a physical NIC
somewhere doing padding), but VMs on the host and the host itself cannot
because the ARP request packets are too small for the ESXi host to
accept.
Someone in the past thought this was worth fixing, and added code to the
vmxnet3 qemu emulation such that if it is receiving packets smaller than
60 bytes to pad the packet out to 60. Unfortunately this code is wrong
(or at least in the wrong place). It does so BEFORE before taking into
account the vnet_hdr at the front of the packet added by the tap device.
As a result, it might add padding, but it never adds enough.
Specifically it adds 10 less (the length of the vnet_hdr) than it needs
to.
The following (hopefully "obviously correct") patch simply swaps the
order of processing the vnet header and the padding. With this patch an
ESXi guest is able to communicate with the host or other local VMs.

ich9: add TCO interface emulation
This interface provides some registers within a 32-byte range and can be
acessed through PCI-to-LPC bridge interface (PMBASE + 0x60).
It's commonly used as a watchdog timer to detect system lockups through
SMIs that are generated -- if TCO_EN bit is set -- on every timeout. If
NO_REBOOT bit is not set in GCS (General Control and Status register),
the system will be resetted upon second timeout if TCO_RLD register
wasn't previously written to prevent timeout.
This patch adds support to TCO watchdog logic and few other features
like mapping NMIs to SMIs (NMI2SMI_EN bit), system intruder detection,
etc. are not implemented yet.

crypto: introduce new module for computing hash digests
Introduce a new crypto/ directory that will (eventually) contain
all the cryptographic related code. This initially defines a
wrapper for initializing gnutls and for computing hashes with
gnutls. The former ensures that gnutls is guaranteed to be
initialized exactly once in QEMU regardless of CLI args. The
block quorum code currently fails to initialize gnutls so it
only works by luck, if VNC server TLS is not requested. The
hash APIs avoids the need to litter the rest of the code with
preprocessor checks and simplifies callers by allocating the
correct amount of memory for the requested hash.

block: update bdrv_drain_all()/bdrv_drain() comments
The doc comments for bdrv_drain_all() and bdrv_drain() are outdated:
* The bdrv_drain() comment is a poor man's bdrv_lock()/bdrv_unlock()

was never really enough because devices keep submitting I/O and op
blockers don't prevent that.
* The bdrv_drain_all() comment is still partially correct but reflects
the nature of the implementation rather than API documentation.
Do make it clear that bdrv_drain() is only appropriate within an

vl: move rom_load_all after machine init done
On ARM, commit ac9d32e39664e060cd1b538ff190980d57ad69e4 postponed the
memory preparation for boot until the machine init done notifier. This
has for consequence to insert ROM at machine init done time.
However the rom_load_all function stayed called before the ROM are
inserted. As a consequence the rom_load_all function does not do
everything it is expected to do, on ARM.
It currently registers the ROM reset notifier but does not iterate through
the registered ROM list. the isrom field is not set properly. This latter
is used to report info in the monitor and also to decide whether the
rom->data can be freed on ROM reset notifier.
To fix that regression the patch moves the rom_load_all call after
machine init done. We also take the opportunity to rename the rom_load_all
function into rom_check_and_resgister_reset() and integrate the
rom_load_done in it.

vfio/pci : Add pba_offset PCI quirk for Chelsio T5 devices
Fix pba_offset initialization value for Chelsio T5 Virtual Function
device. The T5 hardware has a bug in it where it reports a Pending Interrupt
Bit Array Offset of 0x8000 for its SR-IOV Virtual Functions instead
of the 0x1000 that the hardware actually uses internally. As the hardware
doesn't return the correct pba_offset value, add a quirk to instead
return a hardcoded value of 0x1000 when a Chelsio T5 VF device is
detected.
This bug has been fixed in the Chelsio's next chip series T6 but there are
no plans to respin the T5 ASIC for this bug. It is just documented in the
T5 Errata and left it at that.

vfio: Unregister IOMMU notifiers when container is destroyed
On systems with guest visible IOMMU, adding a new memory region onto
PCI bus calls vfio_listener_region_add() for every DMA window. This
installs a notifier for IOMMU memory regions. The notifier is supposed
to be removed vfio_listener_region_del(), however in the case of mixed
PHB (emulated + VFIO devices) when last VFIO device is unplugged and
container gets destroyed, all existing DMA windows stay alive altogether
with the notifiers which are on the linked list which head was in
the destroyed container.
This unregisters IOMMU memory region notifier when a container is
destroyed.

This patch aims at optimizing IRQ handling using irqfd framework.
Instead of handling the eventfds on user-side they are handled on
kernel side using
- the KVM irqfd framework,
- the VFIO driver virqfd framework.
the virtual IRQ completion is trapped at interrupt controller
This removes the need for fast/slow path swap.
Overall this brings significant performance improvements.

Currently the "host" page size alignment API is really aligning to both
host and target page sizes. There is the qemu_real_page_size which can
be used for the actual host page size but it's missing a mask and ALIGN
macro as provided for qemu_page_size. Complete the API. This allows
system level code that cares about the host page size to use a
consistent alignment interface without having to un-needingly align to
the target page size. This also reduces system level code dependency
on the cpu specific TARGET_PAGE_SIZE.

exec: skip MMIO regions correctly in cpu_physical_memory_write_rom_internal
Loading the BIOS in the mac99 machine is interesting, because there is a
PROM in the middle of the BIOS region (from 16K to 32K). Before memory
region accesses were clamped, when QEMU was asked to load a BIOS from
0xfff00000 to 0xffffffff it would put even those 16K from the BIOS file
into the region. This is weird because those 16K were not actually
visible between 0xfff04000 and 0xfff07fff. However, it worked.
After clamping was added, this also worked. In this case, the
cpu_physical_memory_write_rom_internal function split the write in
three parts: the first 16K were copied, the PROM area (second 16K) were
ignored, then the rest was copied.
Problems then started with commit 965eb2f (exec: do not clamp accesses
to MMIO regions, 2015-06-17). Clamping accesses is not done for MMIO
regions because they can overlap wildly, and MMIO registers can be
expected to perform full-width accesses based only on their address
(with no respect for adjacent registers that could decode to completely
different MemoryRegions). However, this lack of clamping also applied
to the PROM area! cpu_physical_memory_write_rom_internal thus failed
to copy the third range above, i.e. only copied the first 16K of the BIOS.
In effect, address_space_translate is expecting _something else_ to do
the clamping for MMIO regions if the incoming length is large. This
"something else" is memory_access_size in the case of address_space_rw,
so use the same logic in cpu_physical_memory_write_rom_internal.

Stop including qemu-common.h in memory.h
Including qemu-common.h from other header files is generally a bad
idea, because it means it's very easy to end up with a circular
dependency. For instance, if we wanted to include memory.h from
qom/cpu.h we'd end up with this loop:
memory.h -> qemu-common.h -> cpu.h -> cpu-qom.h -> qom/cpu.h -> memory.h
Remove the include from memory.h. This requires us to fix up a few
other files which were inadvertently getting declarations indirectly
through memory.h.
The biggest change is splitting the fprintf_function typedef out
into its own header so other headers can get at it without having
to include qemu-common.h.

doesn't handle disabling the timer. Fix it by deleting the timer if
the enable bit is cleared.
The timer won't start periodic ticking if a ONE-SHOT -> PERIODIC mode
change happens after a one-shot tick was completed. Fix it by
re-starting ticking if the timer isn't ticking right now.
To avoid code churning, these two fixes are squashed in one commit.

target-arm: Split DISAS_YIELD from DISAS_WFE
Currently we use DISAS_WFE for both WFE and YIELD instructions.
This is functionally correct because at the moment both of them
are implemented as "yield this CPU back to the top level loop so
another CPU has a chance to run". However it's rather confusing
that YIELD ends up calling HELPER(wfe), and if we ever want to
implement real behaviour for WFE and SEV it's likely to trip us up.
Split out the yield codepath to use DISAS_YIELD and a new
HELPER(yield) function, and have HELPER(wfe) call HELPER(yield).

ahci: fix sdb fis semantics
There are two things to fix here:
The first one is subtle: the PxSACT register in the AHCI HBA has different
semantics from the field it is shadowing, the ACT field in the
Set Device Bits FIS.
In the HBA register, PxSACT acts as a bitfield indicating outstanding
NCQ commands where a set bit indicates a pending NCQ operation. The FIS
field however operates as an RWC register update to PxSACT, where a set
bit indicates a *successfully* completed command.
Correct the FIS semantics. At the same time, move the "clear finished"
action to the SDB FIS generation instead of the register read to mimick
how the other shadow registers work, which always just report the last
reported value from a FIS, and not the most current values which may
not have been reported by a FIS yet.
Lastly and more simply, SATA 3.2 section 13.6.4.2 (and later sections)
all specify that the Interrupt bit for the SDB FIS should always be set
to one for NCQ commands. That's currently the only time we generate this
FIS, so set it on all the time.

ahci: Do not map cmd_fis to generate response
The Register D2H FIS should copy the current values of
the registers instead of just parroting back the same
values the guest sent back to it.
In this case, the SECTOR COUNT variables are actually
not generally meaningful in terms of standard commands
(See ATA8-AC3 Section 9.2 Normal Outputs), so it actually
probably doesn't matter what we put in here.
Meanwhile, we do need to use the Register update FIS from
the NCQ pathways (in error cases), so getting rid of
references to cur_cmd here is a win for AHCI concurrency.

ahci: add get_cmd_header helper
cur_cmd is an internal bookmark that points to the
current AHCI Command Header being processed by the
AHCI state machine. With NCQ needing to occasionally
rely on some of the same AHCI helpers, we cannot use
cur_cmd and will need to grab explicit pointers instead.
In an attempt to begin relying on the cur_cmd pointer
less, add a helper to let us specifically get the pointer
to the command header of particular interest.

While the rest of the AHCI device can rely on a single bookmarked

ahci: correct ncq sector count
uint16_t isn't enough to hold the real sector count, since a value of
zero implies a full 64K sectors, so we need a uint32_t here.
We *could* cheat and pretend that this value is 0-based and fit it in
a uint16_t, but I'd rather waste 2 bytes instead of a future dev's
10 minutes when they forget to +1/-1 accordingly somewhere.

ide: add limit to .prepare_buf()
prepare_buf should not always grab as many descriptors
as it can, sometimes it should self-limit.
For example, an NCQ transfer of 1 sector with a PRDT that
describes 4GiB of data should not copy 4GiB of data, it
should just transfer that first 512 bytes.
PIO is not affected, because the dma_buf_rw dma helpers
already have a byte limit built-in to them, but DMA/NCQ
will exhaust the entire list regardless of requested size.
AHCI 1.3 specifies in section 6.1.6 Command List Underflow that
NCQ is not required to detect underflow conditions. Non-NCQ
pathways signal underflow by writing to the PRDBC field, which
will already occur by writing the actual transferred byte count
to the PRDBC, signaling the underflow.
Our NCQ pathways aren't required to detect underflow, but since our DMA
backend uses the size of the PRDT to determine the size of the transer,
if our PRDT is bigger than the transaction (the underflow condition) it
doesn't cost us anything to detect it and truncate the PRDT.
This is a recoverable error and is not signaled to the guest, in either
NCQ or normal DMA cases.
For BMDMA, the existing pathways should see no guest-visible difference,
but any bytes described in the overage will no longer be transferred
before indicating to the guest that there was an underflow.

ahci: Do not ignore memory access read size
The only guidance the AHCI specification gives on memory access is:
"Register accesses shall have a maximum size of 64-bits; 64-bit access
must not cross an 8-byte alignment boundary."
I interpret this to mean that aligned or unaligned 1, 2 and 4 byte
accesses should work, as well as aligned 8 byte accesses.
In practice, a real Q35/ICH9 responds to 1, 2, 4 and 8 byte reads
regardless of alignment. Windows 7 can be observed making 1 byte
reads to the middle of 32 bit registers to fetch error codes.
Introduce a wrapper to support unaligned accesses to AHCI.
This wrapper will support aligned 8 byte reads, but will make
no effort to support unaligned 8 byte reads, which although they
will work on real hardware, are not guaranteed to work and do
not appear to be used by either Windows or Linux.

s390x/migration: Introduce 2.4 machine
The section footer changes commit f68945d42bab ("Add a protective
section footer") and commit 37fb569c0198 ("Disable section footers
on older machine types") broke migration for any non-versioned
machines.
This pinpoints a problem of s390-ccw machines: it needs to
be versioned to be compatible with future changes in common
code data structures such as section footers.
Let's introduce a version scheme for s390-ccw-virtio machines.
We will use the old s390-ccw-virtio name as alias to the latest
version as all existing libvirt XML for the ccw type were expanded
by libvirt to that name.
The only downside of this patch is, that the old alias s390-ccw
will no longer be available as machines can have only one alias,
but it should not really matter.

s390x/gdb: synchronize cpu state after modifying acrs
Whenever we touch the access control registers, we have to make sure that
the values will make it into kvm. Otherwise the change will simply be lost.
When synchronizing qemu and kvm, a normal KVM_PUT_RUNTIME_STATE does not take
care of these registers. Let's simply trigger a KVM_PUT_FULL_STATE sync,
so the values will directly be written to kvm. The performance overhead can
be ignored and this is much cleaner than manually writing these registers to kvm
via our two supported ways.

s390x/ipl: Fix boot if no bootindex was specified
commit fa92e218df1d ("s390x/ipl: avoid sign extension") introduced
a regression:
qemu-system-s390x -drive file=image.qcow,format=qcow2
does not boot, the bios states
"No virtio-blk device found!"
adding bootindex=1 does boot.
The reason is that the uint32_t as return value will not do the right
thing for the return -1 (default without bootindex).
The bios itself, will interpret a 64bit -1 as autodetect (but it will
interpret 32bit -1 as ccw device address ff.ff.ffff)

block: Fix dirty bitmap in bdrv_co_discard
Unsetting dirty globally with discard is not very correct. The discard may zero
out sectors (depending on can_write_zeroes_with_unmap), we should replicate
this change to destination side to make sure that the guest sees the same data.
Calling bdrv_reset_dirty also troubles mirror job because the hbitmap iterator
doesn't expect unsetting of bits after current position.
So let's do it the opposite way which fixes both problems: set the dirty bits
if we are to discard it.

block/iscsi: add support for request timeouts
libiscsi starting with 1.15 will properly support timeout of iscsi
commands. The default will remain no timeout, but this can
be changed via cmdline parameters, e.g.:
qemu -iscsi timeout=30 -drive file=iscsi://...
If a timeout occurs a reconnect is scheduled and the timed out command
will be requeued for processing after a successful reconnect.
The required API call iscsi_set_timeout is present since libiscsi
1.10 which was released in October 2013. However, due to some bugs
in the libiscsi code the use is not recommended before version 1.15.
Please note that this patch bumps the libiscsi requirement to 1.10
to have all function and macros defined. The patch fixes also a
off-by-one error in the NOP timeout calculation which was fixed
while touching these code parts.

kvm: First step to push iothread lock out of inner run loop
This opens the path to get rid of the iothread lock on vmexits in KVM
mode. On x86, the in-kernel irqchips has to be used because we otherwise
need to synchronize APIC and other per-cpu state accesses that could be
changed concurrently.
Regarding pre/post-run callbacks, s390x and ARM should be fine without
specific locking as the callbacks are empty. MIPS and POWER require
locking for the pre-run callback.
For the handle_exit callback, it is non-empty in x86, POWER and s390.
Some POWER cases could do without the locking, but it is left in
place for now.

memory: let address_space_rw/ld*/st* run outside the BQL
The MMIO case is further broken up in two cases: if the caller does not
hold the BQL on invocation, the unlocked one takes or avoids BQL depending
on the locking strategy of the target memory region and its coalesced
MMIO handling. In this case, the caller should not hold _any_ lock
(a friendly suggestion which is disregarded by virtio-scsi-dataplane).

As memory_region_read/write_accessor will now be run also without BQL held,
we need to move coalesced MMIO flushing earlier in the dispatch process.

memory: Add global-locking property to memory regions
This introduces the memory region property "global_locking". It is true
by default. By setting it to false, a device model can request BQL-free
dispatching of region accesses to its r/w handlers. The actual BQL
break-up will be provided in a separate patch.

main-loop: introduce qemu_mutex_iothread_locked
This function will be used to avoid recursive locking of the iothread lock
whenever address_space_rw/ld*/st* are called with the BQL held, which is
almost always the case.
Tracking whether the iothread is owned is very cheap (just use a TLS
variable) but requires some care because now the lock must always be
taken with qemu_mutex_lock_iothread(). Previously this wasn't the case.
Outside TCG mode this is not a problem. In TCG mode, we need to be
careful and avoid the "prod out of compiled code" step if already
in a VCPU thread. This is easily done with a check on current_cpu,
i.e. qemu_in_vcpu_thread().
Hopefully, multithreaded TCG will get rid of the whole logic to kick
VCPUs whenever an I/O event occurs!

Fix irq route entries exceeding KVM_MAX_IRQ_ROUTES
Last month, we experienced several guests crash(6cores-8cores), qemu logs
display the following messages:
qemu-system-x86_64: /build/qemu-2.1.2/kvm-all.c:976:
kvm_irqchip_commit_routes: Assertion `ret == 0' failed.
After analysis and verification, we can confirm it's irq-balance
daemon(in guest) leads to the assertion failure. Start a 8 core guest with
two disks, execute the following scripts will reproduce the BUG quickly:
irq_affinity.sh
========================================================================
vda_irq_num=25
vdb_irq_num=27
while [ 1 ]
do
for irq in {1,2,4,8,10,20,40,80}
do
echo $irq > /proc/irq/$vda_irq_num/smp_affinity
echo $irq > /proc/irq/$vdb_irq_num/smp_affinity
dd if=/dev/vda of=/dev/zero bs=4K count=100 iflag=direct
dd if=/dev/vdb of=/dev/zero bs=4K count=100 iflag=direct
done
done
========================================================================
QEMU setup static irq route entries in kvm_pc_setup_irq_routing(), PIC and
IOAPIC share the first 15 GSI numbers, take up 23 GSI numbers, but take up
38 irq route entries. When change irq smp_affinity in guest, a dynamic route
entry may be setup, the current logic is: if allocate GSI number succeeds,
a new route entry can be added. The available dynamic GSI numbers is
1021(KVM_MAX_IRQ_ROUTES-23), but available irq route entries is only
986(KVM_MAX_IRQ_ROUTES-38), GSI numbers greater than route entries.
irq-balance's behavior will eventually leads to total irq route entries
exceed KVM_MAX_IRQ_ROUTES, ioctl(KVM_SET_GSI_ROUTING) fail and
kvm_irqchip_commit_routes() trigger assertion failure.
This patch fix the BUG.

virtio-ccw: complete handling of guest-initiated resets
For a guest-initiated reset, we need to not only reset the virtio device,
but also reset the VirtioCcwDevice into a clean state. This includes
resetting the indicators, or else a guest will not be able to e.g.
switch from classic interrupts to adapter interrupts.
Split off this routine into a new function virtio_ccw_reset_virtio()
to make the distinction between resetting the virtio-related devices
and the base subchannel device clear.

hw/arm/virt: Make block devices default to virtio
Now we have virtio-pci, we can make the virt board's default block
device type be IF_VIRTIO. This allows users to use simplified
command lines that don't have to explicitly create virtio-pci-blk
devices; the -hda &c very short options now also work.
This means we also need to set no_cdrom to avoid getting a
default cdrom device -- this is needed because the virtio-blk
device will fail if it is connected to a block backend with
no media, which is what the default cdrom device typically is.
Providing a cdrom with media via -cdrom will succeed, but silently
create a device with non-removable medium. this is probably
not really what the user wants, but is the best we can do now.
Note that this change means that some command lines which used
to work (by accident) will stop working. Where a drive was connected
manually to a device but without 'if=none' being specified, we
used to treat this as an IDE drive, which we would then not autoplug
because the board doesn't support IDE. Now we will treat it as a
virtio disk and autoplug it, which means the attempt to use the
drive manually will fail:
qemu-system-arm: -drive file=img.qcow2,id=foo: Drive 'foo' is already
in use because it has been automatically connected to another device
(did you need 'if=none' in the drive options?)
The command line will have to be changed to include 'if=none', as the
error message suggests.

qdev-properties-system: Improve error message for drive assignment conflict
If the user forgot if=none on their drive specification they're likely
to get an error message because the drive is assigned once automatically
by QEMU and once by the manual id=/drive= user command line specification.
Improve the error message produced in this case to explicitly guide the
user towards if=none.
We rephrase the "drive conflict but not for an if=something" error as
well to keep the wording in line.
The two cases that change are:
(1) Drive specified as to be auto-connected and also manually connected
(and the board does handle this if= type):
qemu-system-x86_64 -nodefaults -display none \
-drive if=scsi,file=tmp.qcow2,id=foo -device ide-hd,drive=foo
Previously:
qemu-system-x86_64: -device ide-hd,drive=foo: Property 'ide-hd.drive'
can't take value 'foo', it's in use
Now:
qemu-system-x86_64: -device ide-hd,drive=foo: Drive 'foo' is already in
use because it has been automatically connected to another device (did
you need 'if=none' in the drive options?)
(2) Drive specified to be manually connected in two different ways:
qemu-system-x86_64 -nodefaults -display none \
-drive if=none,file=tmp.qcow2,id=foo -device ide-hd,drive=foo \
-device ide-hd,drive=foo
Previously:
qemu-system-x86_64: -device ide-hd,drive=foo: Property 'ide-hd.drive'
can't take value 'foo', it's in use
Now:
qemu-system-x86_64: -device ide-hd,drive=foo: Drive 'foo' is already in
use by another device

qdev-properties-system: Change set_pointer's parse callback to use Error
Instead of having set_pointer() call a parse callback which returns
an error number that we then convert to an Error string with
error_set_from_qdev_prop_error(), make the parse callback take an
Error** and set the error itself. This will allow parse routines
to provide more helpful error messages than the generic ones.

target-mips: raise RI exceptions when FIR.PS = 0
64-bit paired-single (PS) floating point data type is optional in the
pre-Release 6.
It has to raise RI exception when PS type is not implemented. (FIR.PS = 0)
(The PS data type is removed in the Release 6.)
Loongson-2E and Loongson-2F don't have any implementation field in
FCSR0(FIR) but do support PS data format, therefore for these cores RI will
not be signalled regardless of PS bit.

hw/mips: Do not clear BEV for MIPS malta kernel load
The BEV flag controls whether the boot exception vector is still
in place when starting a kernel. When cleared the exception vector
at EBASE (or hard coded address of 0x80000000) is used instead.
The early stages of the linux kernel would benefit from BEV still
being set to ensure any faults get handled by the boot rom exception
handlers. This is a moot point for system qemu as there aren't really
any BEV handlers, but there are other good reasons to change this...
The UHI (semi-hosting interface) defines special behaviours depending
on whether an application starts in an environment with BEV set or
cleared. When BEV is set then UHI assumes that a bootloader is
relatively dumb and has no advanced exception handling logic.
However, when BEV is cleared then UHI assumes that the bootloader
has the ability to handle UHI exceptions with its exception handlers
and will unwind and forward UHI SYSCALL exceptions to the exception
vector that was installed prior to running the application.

hw/pci-bridge: format special OFW unit address for PXB host
We have agreed that OpenFirmware device paths in the "bootorder" fw_cfg
file should follow the pattern
/pci@i0cf8,%x/...
for devices that live behind an extra root bus. The extra root bus in
question is the %x'th among the extra root buses. (In other words, %x
gives the position of the affected extra root bus relative to the other
extra root buses, in bus_nr order.) %x starts at 1, and is formatted in
hex.
The portion of the unit address that comes before the comma is dynamically
taken from the main host bridge, similarly to sysbus_get_fw_dev_path().

hw/core: explicit OFW unit address callback for SysBusDeviceClass
The sysbus_get_fw_dev_path() function formats OpenFirmware device path
nodes ("driver-name@unit-address") for sysbus devices. The first choice
for "unit-address" is the base address of the device's first MMIO region.
The second choice is its first IO port.
However, if two sysbus devices with the same "driver-name" lack both MMIO
and PIO resources, then there is no good way to distinguish them based on
their OFW nodes, because in this case unit-address is omitted completely
for both devices. An example is TYPE_PXB_HOST ("pxb-host").
For the sake of such devices, introduce the explicit_ofw_unit_address()
"virtual member function". With this function, each sysbus device in the
same SysBusDeviceClass can state its own address.

hw/pci-bridge: disable SHPC in PXB
OVMF downloads the ACPI linker/loader script from QEMU when the edk2 PCI
Bus driver globally signals the firmware that PCI enumeration and resource
allocation have completed. At this point QEMU regenerates the ACPI payload
in an fw_cfg read callback, and this is when the PXB's _CRS gets
populated.
Unfortunately, when this happens, the PCI_COMMAND_MEMORY bit is clear in
the root bus's command register, *unlike* under SeaBIOS. The consequences
unfold as follows:
- When build_crs() fetches dev->io_regions[i].addr, it is all-bits-one,
because pci_update_mappings() --> pci_bar_address() calculated it as
PCI_BAR_UNMAPPED, due to the PCI_COMMAND_MEMORY bit being clear.
- Consequently, the SHPC MMIO BAR (bar 0) of the bridge is not added to
the _CRS, *despite* having been programmed in PCI config space.
- Similarly, the SHPC MMIO BAR of the PXB is not removed from the main
root bus's DWordMemory descriptor.
- Guest OSes (Linux and Windows alike) notice the pre-programmed SHPC BAR
within the PXB's config space, and notice that it conflicts with the
main root bus's memory resource descriptors. Linux reports
pci 0000:04:00.0: BAR 0: can't assign mem (size 0x100)
pci 0000:04:00.0: BAR 0: trying firmware assignment [mem
0x88200000-0x882000ff 64bit]
pci 0000:04:00.0: BAR 0: [mem 0x88200000-0x882000ff 64bit] conflicts
with PCI Bus 0000:00 [mem
0x88200000-0xfebfffff]
While Windows Server 2012 R2 reports
https://technet.microsoft.com/en-us/library/cc732199%28v=ws.10%29.aspx
This device cannot find enough free resources that it can use. If you
want to use this device, you will need to disable one of the other
devices on this system. (Code 12)
This issue was apparently encountered earlier, see the "hack" in:
https://lists.nongnu.org/archive/html/qemu-devel/2015-01/msg02983.html
and the current hole-punching logic in build_crs() and build_ssdt() is
probably supposed to remedy exactly that problem -- however, for OVMF they
don't work, because at the end of the PCI enumeration and resource
allocation, which cues the ACPI linker/loader client, the command register
is clear.
The "shpc" property of "pci-bridge", introduced in the previous patches,
allows us to disable the standard hotplug controller cleanly, eliminating
the SHPC bar and the conflict.

util/qemu-sockets: improve ai_flag hints for ipv6 hosts
*) Do not use AI_ADDRCONFIG on listening sockets, because this flag
makes it impossible to explicitly listen on '127.0.0.1' if no global
ipv4 address is configured additionally, making this a very
uncomfortable option.
*) Add AI_V4MAPPED hint for connecting sockets.
If your system is globally only connected via ipv6 you often still want
to be able to use '127.0.0.1' and 'localhost' (even if localhost doesn't
also have an ipv6 entry).
For example, PVE - unless explicitly asking for insecure mode - uses
ipv4 loopback addresses with QEMU for live migrations tunneled over SSH.
These fail to start because AI_ADDRCONFIG makes getaddrinfo refuse to
work with '127.0.0.1'.
As for the AI_V4MAPPED flag: glibc uses it by default, and providing
non-0 flags removes it. I think it makes sense to use it.
I also want to point out that glibc explicitly sidesteps POSIX standards
when passing 0 as hints by then assuming both AI_V4MAPPED and
AI_ADDRCONFIG (the latter being a rather weird choice IMO), while
according to POSIX.1-2001 it should be assumed 0. (glibc considers its
choice an improvement.)
Since either AI_CANONNAME or AI_PASSIVE are passed in our cases, glibc's
default flags in turn are disabled again unless explicitly added, which
I do with this patch.

remove libdecnumber/dpd/decimal128Local.h
Commit 72ac97cdfc added two equivalent versions of decimal128Local.h,
one in libdecnumber/dpd/ and another in include/libdecnumber/dpd/.
Being identical by the code, the two files however differs in the
licensing terms. The one in libdecnumber/dpd/ (which is being
removed by this patch) is licensed as GPL3.1 (plus gcc runtime
exception), which, as far as I know, is not compatible with GPL-2.
This file is not used (it is included from
include/libdecnumber/dpd/decimal128.h, so version in include/ is
used).
More, the version in include/ can also be removed, since none
of the 3 defines from that file are actually used by the code.
Even more, one of the defines from there, decimal128SetSign,
is redefined (to equivalent value) in libdecnumber/dpd/decimal128.c,
but again, never used.
What a mess...

Revert "xen-hvm: increase maxmem before calling xc_domain_populate_physmap"
This reverts commit c1d322e6048796296555dd36fdd102d7fa2f50bf.
The original commit fixes a bug when assigning a large number of
devices which require option roms to a guest. (One known
configuration that needs extra memory is having more than 4 emulated
NICs assigned. Three or fewer NICs seems to work without this
functionality.)
However, by unilaterally increasing maxmem, it introduces two
problems.
First, now libxl's calculation of the required maxmem during migration
is broken -- any guest which exercised this functionality will fail on
migration. (Guests which have the default number of devices are not
affected.)
Secondly, it makes it impossible for a higher-level toolstack or
administer to predict how much memory a VM will actually use, making
it much more difficult to effectively use all of the memory on a
machine.

balloon: add a feature bit to let Guest OS deflate balloon on oom
Excessive virtio_balloon inflation can cause invocation of OOM-killer,
when Linux is under severe memory pressure. Various mechanisms are
responsible for correct virtio_balloon memory management. Nevertheless it
is often the case that these control tools does not have enough time to
react on fast changing memory load. As a result OS runs out of memory and
invokes OOM-killer. The balancing of memory by use of the virtio balloon
should not cause the termination of processes while there are pages in the
balloon. Now there is no way for virtio balloon driver to free memory at
the last moment before some process get killed by OOM-killer.
This does not provide a security breach as balloon itself is running
inside Guest OS and is working in the cooperation with the host. Thus
some improvements from Guest side should be considered as normal.
To solve the problem, introduce a virtio_balloon callback which is
expected to be called from the oom notifier call chain in out_of_memory()
function. If virtio balloon could release some memory, it will make the
system return and retry the allocation that forced the out of memory
killer to run.
This behavior should be enabled if and only if appropriate feature bit
is set on the device. It is off by default.
This functionality was recently merged into vanilla Linux.

raw-posix: Introduce hdev_is_sg()
Until now, an SG device was identified only by checking if its path
started with "/dev/sg". Then, hdev_open() would set the bs->sg flag
accordingly. The patch relies on the actual properties of the device
instead of the specified file path.
To this end, test for an SG device (e.g. /dev/sg0) by ensuring that
all of the following holds:
- The specified file name corresponds to a character device
- The device supports the SG_GET_VERSION_NUM ioctl
- The device supports the SG_GET_SCSI_ID ioctl

Fix migration in case of scsi-generic
During migration, QEMU uses fsync()/fdatasync() on the open file
descriptor for read-write block devices to flush data just before
stopping the VM.
However, fsync() on a scsi-generic device returns -EINVAL which
causes the migration to fail. This patch skips flushing data in case
of an SG device, since submitting SCSI commands directly via an SG
character device (e.g. /dev/sg0) bypasses the page cache completely,
anyway.
Note that fsync() not only flushes the page cache but also the disk
cache. The scsi-generic device never sends flushes, and for
migration it assumes that the same SCSI device is used by the
destination host, so it does not issue any SCSI SYNCHRONIZE CACHE
(10) command.
Finally, remove the bdrv_is_sg() test from iscsi_co_flush() since
this is now redundant (we flush the underlying protocol at the end
of bdrv_co_flush() which, with this patch, we never reach).

throttle: Check current timers before updating any_timer_armed[]
Calling throttle_group_config() cancels all timers from a particular
BlockDriverState, so any_timer_armed[] should be updated accordingly.
However, with the current code it may happen that a timer is armed in
a different BlockDriverState from the same group, so any_timer_armed[]
would be set to false in a situation where there is still a timer
armed.
The consequence is that we might end up with two timers armed. This
should not have any noticeable impact however, since all accesses to
the ThrottleGroup are protected by a lock, and the situation would
become normal again shortly thereafter as soon as all timers have been
fired.
The correct way to solve this is to check that we're actually
cancelling a timer before updating any_timer_armed[].

qmp: Wean off qerror_report()
The traditional QMP command handler interface
int qmp_FOO(Monitor *mon, const QDict *params, QObject **ret_data);
doesn't provide for returning an Error object. Instead, the handler
is expected to stash it in the monitor with qerror_report().
When we rebased QMP on top of QAPI, we didn't change this interface.
Instead, commit 776574d introduced "middle mode" as a temporary aid
for converting existing QMP commands to QAPI one by one. More than
three years later, we're still using it.
Middle mode has two effects:
* Instead of the native input marshallers
static void qmp_marshal_input_FOO(QDict *, QObject **, Error **)
it generates input marshallers conforming to the traditional QMP
command handler interface.
* It suppresses generation of code to register them with
qmp_register_command()
This permits giving them internal linkage.
As long as we need qmp-commands.hx, we can't use the registry behind
qmp_register_command(), so the latter has to stay for now.
The former has to go to get rid of qerror_report(). Changing all QMP
commands to fit the QAPI mold in one go was impractical back when we
started, but by now there are just a few stragglers left:
do_qmp_capabilities(), qmp_qom_set(), qmp_qom_get(), qmp_object_add(),
qmp_netdev_add(), do_device_add().
Switch middle mode to generate native input marshallers, and adapt the
stragglers. Simplifies both the monitor code and the stragglers.
Rename do_qmp_capabilities() to qmp_capabilities(), and
do_device_add() to qmp_device_add, because that's how QMP command
handlers are named today.

qerror: Clean up QERR_ macros to expand into a single string
These macros expand into error class enumeration constant, comma,
string. Unclean. Has been that way since commit 13f59ae.
The error class is always ERROR_CLASS_GENERIC_ERROR since the previous
commit.
Clean up as follows:
* Prepend every use of a QERR_ macro by ERROR_CLASS_GENERIC_ERROR, and
delete it from the QERR_ macro. No change after preprocessing.
* Rewrite error_set(ERROR_CLASS_GENERIC_ERROR, ...) into
error_setg(...). Again, no change after preprocessing.

QemuOpts: Wean off qerror_report_err()
qerror_report_err() is a transitional interface to help with
converting existing monitor commands to QMP. It should not be used
elsewhere.
The only remaining user in qemu-option.c is qemu_opts_parse(). Is it
used in QMP context? If not, we can simply replace
qerror_report_err() by error_report_err().
The uses in qemu-img.c, qemu-io.c, qemu-nbd.c and under tests/ are
clearly not in QMP context.
The uses in vl.c aren't either, because the only QMP command handlers
there are qmp_query_status() and qmp_query_machines(), and they don't
call it.
Remaining uses:
* drive_def(): Command line -drive and such, HMP drive_add and pci_add
* hmp_chardev_add(): HMP chardev-add
* monitor_parse_command(): HMP core
* tmp_config_parse(): Command line -tpmdev
* net_host_device_add(): HMP host_net_add
* net_client_parse(): Command line -net and -netdev
* qemu_global_option(): Command line -global
* vnc_parse_func(): Command line -display, -vnc, default display, HMP
change, QMP change. Bummer.
* qemu_pci_hot_add_nic(): HMP pci_add
* usb_net_init(): Command line -usbdevice, HMP usb_add
Propagate errors through qemu_opts_parse(). Create a convenience
function qemu_opts_parse_noisily() that passes errors to
error_report_err(). Switch all non-QMP users outside tests to it.
That leaves vnc_parse_func(). Propagate errors through it. Since I'm
touching it anyway, rename it to vnc_parse().

qdev-monitor: Fix check for full bus
Property bus has always been too screwed up to be really usable for
values other than plain bus IDs. This just fixes a bug that crept in
in commit 1395af6 "qdev: add a maximum device allowed field for the
bus."
It doesn't always fail when it should:
$ qemu-system-x86_64 -nodefaults -device virtio-serial-pci -device virtio-rng-device,bus=pci.0/virtio-serial-pci/virtio-bus
Happily plugs the virtio-rng-device into the virtio-bus provided by
virtio-serial-pci, even though its only slot is already occupied by a
virtio-serial-device.
And sometimes fails when it shouldn't:
$ qemu-system-x86_64 -nodefaults -device virtio-serial-pci -device virtserialport,bus=virtio-bus/virtio-serial-device
Yes, the virtio-bus is full, but the virtio-serial-bus provided by
virtio-serial-device isn't, and that's the one we're trying to use.
Root cause: we check "bus full" when we resolve the first element of
the path. That's the correct one only when it's also the last one.
Fix by moving the "bus full" check to right before we return a bus.

qdev-monitor: Stop error avalanche in qbus_find_recursive()

qemu-system-x86_64: -device virtio-rng-device,bus=virtio-bus: Bus 'virtio-bus' is full

qemu-system-x86_64: -device virtio-rng-device,bus=virtio-bus: Bus 'virtio-bus' not found
qbus_find_recursive() reports the "is full" error itself, and leaves
reporting "not found" to its caller. The result is confusion. Write
it a function contract that permits leaving all error reporting to the
caller, and implement it. Update callers to detect and report "is
full".
Screwed up when commit 1395af6 added the max_dev limit and the "is
full" error condition to enforce it.

The monitor currently has one helper, mon_get_cpu() which will return

all the target agnostic users really just want the cpu pointer. These
users then need to use the target-specifically defined ENV_GET_CPU to
navigate back up to the CPU from the ENV. Split the API for the two
uses cases to remove all need for ENV_GET_CPU.

monitor: remove debug prints
The preferred solution is to use tracepoints and there
is good chance of bitrot with the debug prints not being
enabled at compile time. Remove them.

m68k: fix usp processing on interrupt entry and exception exit
The action to potentially switch sp register is not occurring at the correct
point in the interrupt entry or exception exit sequences.
For the interrupt entry case the sp on entry is used to create the stack
exception frame - but this may well be the user stack pointer, since we
haven't done the switch yet. Re-order the flow to switch the sp regs then
use the current sp to create the exception frame.
For the return from exception case the code is unwinding the sp after
switching sp registers. But it should always unwind the supervisor sp
first, then carry out any required sp switch.
Note that these problems don't effect operation unless the user sp bit is
set in the CACR register. Only a single sp is used in the default power up
state. Previously Linux only used this single sp mode. But modern versions
of Linux use the user sp mode now, so we need correct behavior for Linux
to work.

qom: Don't pass string table to object_get_enum() function
Now that properties can be explicitly registered as an enum
type, there is no need to pass the string table to the
object_get_enum() function. The object property registration
already has a pointer to the string table.
In changing this method signature, the hostmem backend object

code, which simplifies it somewhat.

qom: Add an object_property_add_enum() helper function
A QOM property can be parsed as enum using the visit_type_enum()
helper function, but this forces callers to use the more complex
generic object_property_add() method when registering it. It
also requires that users of that object have access to the
string map when they want to read the property value.
This patch introduces a specialized object_property_add_enum()
method which simplifies the use of enum properties, so the
setters/getters directly get passed the int value.
typedef enum {
MYDEV_TYPE_FROG,
MYDEV_TYPE_ALLIGATOR,
MYDEV_TYPE_PLATYPUS,
MYDEV_TYPE_LAST
} MyDevType;
Then provide a table of enum <-> string mappings
static const char *const mydevtypemap[MYDEV_TYPE_LAST + 1] = {
[MYDEV_TYPE_FROG] = "frog",
[MYDEV_TYPE_ALLIGATOR] = "alligator",
[MYDEV_TYPE_PLATYPUS] = "platypus",
[MYDEV_TYPE_LAST] = NULL,
};
Assuming an object struct of
typedef struct {
Object parent_obj;
MyDevType devtype;
...other fields...
} MyDev;
The property can then be registered as follows:
static int mydev_prop_get_devtype(Object *obj,
Error **errp G_GNUC_UNUSED)
{
MyDev *dev = MYDEV(obj);
return dev->devtype;
}
static void mydev_prop_set_devtype(Object *obj,
int value,
Error **errp G_GNUC_UNUSED)
{
MyDev *dev = MYDEV(obj);
dev->devtype = value;
}
object_property_add_enum(obj, "devtype",
mydevtypemap, "MyDevType",
mydev_prop_get_devtype,
mydev_prop_set_devtype,
NULL);
Note there is no need to check the range of 'value' in
the setter, because the string->enum conversion code will
have already done that and reported an error as required.

qom: Add object_new_with_props() / object_new_withpropv() helpers
It is reasonably common to want to create an object, set a
number of properties, register it in the hierarchy and then
mark it as complete (if a user creatable type). This requires
quite a lot of error prone, verbose, boilerplate code to achieve.
First a pair of functions object_set_props() / object_set_propv()
are added which allow for a list of objects to be set in
one single API call.
Then object_new_with_props() / object_new_with_propv() constructors
are added which simplify the sequence of calls to create an
object, populate properties, register in the object composition
tree and mark the object complete, into a single method call.
Usage would be:
Error *err = NULL;
Object *obj;
obj = object_new_with_propv(TYPE_MEMORY_BACKEND_FILE,
object_get_objects_root(),
"hostmem0",
&err,
"share", "yes",
"mem-path", "/dev/shm/somefile",
"prealloc", "yes",
"size", "1048576",
NULL);
Note all property values are passed in string form and will
be parsed into their required data types, using normal QOM
semantics for parsing from string format.

vl: Create (most) objects before creating chardev backends
Some types of object must be created before chardevs, other types of
object must be created after chardevs. As such there is no option but
to create objects in two phases.
This takes the decision to create as many object types as possible
right away before anyother backends are created, and only delay
creation of those few which have an explicit dependency on the
chardevs. Hopefully the set which need delaying will remain small
over time.

semihosting: add --semihosting-config arg sub-argument
Add new "arg" sub-argument to the --semihosting-config allowing the user
to pass multiple input arguments separately. It is required for example
by UHI semihosting to construct argc and argv.
Also, update ARM semihosting to support new option (at the moment it is
the only target which cares about arguments).
If the semihosting is enabled and no semihosting args have been specified,
then fall back to -kernel/-append. The -append string is split on whitespace
before initializing semihosting.argv[1..n]; this is different from what
QEMU MIPS machines' pseudo-bootloaders do (i.e. argv[1] contains the whole
-append), but is more intuitive from UHI user's point of view and Linux
kernel just does not care as it concatenates argv[1..n] into single cmdline
string anyway.

target-arm: Do not reset sysregs marked as ALIAS
cp_reg_reset() is called from g_hash_table_foreach() which does not
define a specific ordering of the hash table iteration. Thus doing reset
for registers marked as ALIAS would give an ambiguous result when
resetvalue is different for original and alias registers. Exit
cp_reg_reset() early when passed an alias register. Then clean up alias
register definitions from needless resetvalue and resetfn.
In particular, this fixes a bug in the handling of the PMCR register,
which had different resetvalues for its 32 and 64-bit views.

mc146818rtc: Reset the periodic timer on load
When loading a VM from a snapshot or migration, clock changes can cause
the periodic timer to stall or loop rapidly.
qemu-timer has a reset notifier mechanism that is used to avoid timer
stalls or loops if the host clock changes while the VM is running when
using QEMU_CLOCK_HOST. However, when loading a snapshot or migration,
qemu-timer is initialized and fires the reset notifier before
mc146818rtc is initialized and has registered its reset handler. In
addition, this mechanism isn't used when using QEMU_CLOCK_REALTIME,
which might also change when loading a snapshot or migration.
To correct that problem, this commit resets the periodic timer after
loading from a snapshot or migration if the clock has either jumped
backward or has jumped forward by more than the clock jump limit that
is used by the reset notifier code in qemu-timer.

qemu-timer: Call clock reset notifiers on forward jumps
Commit 691a0c9c introduced a mechanism by which QEMU_CLOCK_HOST can
notify other parts of the emulator when the host clock has jumped
backward. This is used to avoid stalling timers that were scheduled
based on the host clock.
However, if the host clock jumps forward, then timers that were
scheduled based on the host clock may fire rapidly and cause other
problems. For example, the mc146818rtc periodic timer will block
execution of the VM and consume host CPU while firing every interrupt
for the time period that was skipped by the host clock.
To correct that problem, this commit fires the reset notification if the
host clock jumps forward by more than a hard-coded limit. The limit is
currently set to a value of 60 seconds, which should be small enough to
prevent excessive timer loops, but large enough to avoid frequent resets
in idle VMs.

support and we fall back to QEMU virtio-net.
This gives a very small performance gain, but the disadvantage
is that guest now controls which virtio code is running
(qemu or vhost) so our attack surface is doubled.
This patch will enable vhost unconditionally whenever it's requested.
For compatibility, enable vhost when vhostforce is set, as well.

pci: Don't register a specialized 'config_write' if default behavior is intended
Few devices have their specialized 'config_write' methods which simply
call 'pci_default_write_config' followed by a 'msix_write_config' or
'msi_write_config' calls, using exact same arguments.
This is unnecessary as 'pci_default_write_config' already invokes
'msi_write_config' and 'msix_write_config'.
Also, since 'pci_default_write_config' is the default 'config_write'
handler, we can simply avoid the registration of these specialized
versions.

hw/core: rebase sysbus_get_fw_dev_path() to g_strdup_printf()
This is done mainly for improving readability, and in preparation for the
next patch, but Markus pointed out another bonus for the string being
returned:
"No arbitrary length limit. Before the patch, it's 39 characters, and the
code breaks catastrophically when qdev_fw_name() is longer: the second
snprintf() is called with its first argument pointing beyond path[], and
its second argument underflowing to a huge size."

commit ea96bc629cbd52be98b2967a4b4f72e91dfc3ee4 doesn't match the patch
submitted by Laszlo to qemu-devel. We reuse pc_q35_2_4_machine_options()
inside pc_q35_2_3_machine_options(), so we need to undo the no_floppy
change in pc_q35_2_3_machine_options().
(This discrepancy was due to a bad merge.)
This restores the previous behavior where all the 2.3 and older machines
had no_floppy=0.

qemu-ga: adding vss-[un]install options
Existing command line options include '-s install' and '-s uninstall'.
These options install/uninstall both Windows QEMU GA service
and optional VSS COM server. The QEMU GA Windows service allows
always-on serving guest agent's QMP commands and VSS COM server
enables guest agent integration with Volume Shadow Service.
This commit introdices new options '-s vss-install' and '-s vss-uninstall',
affecting only GA VSS COM server registration. The new options are useful
for registering and unregistering the COM server during MSI installation,
upgrade and uninstallation.

qemu-log: Open file for logging when specified
qemu-log defaults to stderr when there is no '-D' option mentioned on command
line. When '-D' option is specified, we also need to specify '-d' option for it
to use the specified logfile. When using monitor to enable logging this is
troublesome since there will be no '-d' option because of which monitor dumps
the logs to stderr.
Fix this by opening the log file when '-D' is specified on the command line.
Also fix an ancient comment which does not hold true since changing location and
log level has now been streamlined.

s390x: Switch to s390-ccw machine as default
We now finally have TCG support for the basic set of instructions necessary
to run the s390-ccw machine. That means in any aspect possible that machine
type is now superior to the legacy s390-virtio machine.
Switch over to the ccw machine as default. That way people don't get a halfway
broken machine with the s390x target.

This patch adds support for PER Breaking-Event-Address register. Like
real hardware, it save the current PSW address when the PSW address is
changed by an instruction. We have to take care of optimizations QEMU
does, a branch to the next instruction is still a branch.
This register is copied to low core memory when a program exception

For the PER storage-alteration event we can use the QEMU watchpoint

save the event. Unfortunately the current code does not provide the
address space used to trigger the watchpoint. For now we assume it comes

translate-all: fix watchpoints if retranslation not possible
The tb_check_watchpoint function currently assumes that all memory
access is done either directly through the TCG code or through an
helper which knows its return address. This is obviously wrong as the
helpers use cpu_ldxx/stxx_data functions to access the memory.
Instead of aborting in that case, don't try to retranslate the code, but
assume that the CPU state (and especially the program counter) has been
saved before calling the helper. Then invalidate the TB based on this
address.

target-s390x: PER instruction-fetch event support
For the PER instruction-fetch, we can't use the QEMU breakpoint
infrastructure as it triggers for a single address and not a full
address range, and as it actually stop before the instruction and
not before.
We therefore call an helper with the just fetched instruction address,
which check if the address is within the PER address range. If it is
the case, an event is recorded and will be signaled through an
exception.
Note that we implement here the PER-3 behaviour, that is an invalid
opcode is not considered as an instruction fetch. Without PER-3 this
behavious is undefined.

We don't need to care about the cases using goto_tb, as we have disabled
them in the previous patch.

target-s390x: basic PER event handling
This patch add basic support to generate PER exceptions. It adds two
fields to the cpu structure to record for the PER address and PER
code & ATMID values. When an exception is triggered and a PER event is
pending, the two PER values are copied to the lowcore area.
At the end of an instruction, an helper is checking for a possible
pending PER event and triggers an exception in that case. For that to
work with branches, we need to disable TB chaining when PER is
activated. Fortunately it's already in the TB flags.
Finally in case of a SERVICE CALL exception, we need to trigger the PER
exception immediately after.

target-s390x: mvc_fast_memmove: access memory through softmmu
mvc_fast_memmove is bypassing the softmmu functions, getting the
physical source and destination addresses using the mmu_translate
function and accessing the corresponding physical memory. This
prevents watchpoints to work correctly.
Instead use the tlb_vaddr_to_host function to get the host addresses
corresponding to the guest source and destination addresses through the
softmmu code and fallback to the byte level code in case the
corresponding address are not in the QEMU TLB or being examined through
a watchpoint. As a bonus it works even for area crossing pages by
splitting the are into chunks contained in a single page, bringing some
performances improvements. We can therefore remove the 8-byte
loads/stores method, as it is now quite unlikely to be used.
At the same time change the name of the function to fast_memmove as it's
not specific to mvc and use the same argument order as the C memmove
function.

commit 45c874ebbae661238bfa3c0534480ebe2940b112
Author: Laurent Vivier <laurent@vivier.eu>

linux-user: ioctl() command type is int
When executing a 64bit target chroot on 64bit host,
the ioctl() command can mismatch.
It seems the previous commit doesn't solve the problem in
my case:
9c6bf9c7 linux-user: Fix ioctl cmd type mismatch on 64-bit targets
For example, a ppc64 chroot on an x86_64 host:
bash-4.3# ls
Unsupported ioctl: cmd=0x80087467
Unsupported ioctl: cmd=0x802c7415
The origin of the problem is in syscall.c:do_ioctl().
static abi_long do_ioctl(int fd, abi_long cmd, abi_long arg)
In this case (ppc64) abi_long is long (on the x86_64), and
cmd = 0x0000000080087467
then
if (ie->target_cmd == cmd)
target_cmd is int, so target_cmd = 0x80087467
and to compare an int with a long, the sign is extended to 64bit,
so the comparison is:
if (0xffffffff80087467 == 0x0000000080087467)
which doesn't match whereas it should.
This patch uses int in the case of the target command type
instead of abi_long.

linux-user: use __get_user and __put_user in cmsg conversions
The target payloads in cmsg conversions may not have the alignment
required by the host. Using the get_user and put_user functions is
the easiest way to handle this and also do the byte-swapping we
require.
(Note that prior to this commit target_to_host_cmsg was incorrectly
using __put_user() rather than __get_user() for the SCM_CREDENTIALS
conversion, which meant it wasn't getting the benefit of the
misalignment handling.)

linux-user: Fix length handling in host_to_target_cmsg
The previous code for handling payload length when converting
cmsg structures from host to target had a number of problems:
* we required the msg->msg_controllen to declare the buffer
to have enough space for final trailing padding (we were
checking against CMSG_SPACE), whereas the kernel does not
require this, and common userspace code assumes this. (In
particular, glibc's "try to talk to nscd" code that it will
run on startup will receive a cmsg with a 4 byte payload and
only allocate 4 bytes for it, which was causing us to do
the wrong thing on architectures that need 8-alignment.)
* we weren't correctly handling the fact that the SO_TIMESTAMP
payload may be larger for the target than the host
* we weren't marking the messages with MSG_CTRUNC when we did
need to truncate a message that wasn't truncated by the host,
but were instead logging a QEMU message; since truncation is
always the result of a guest giving us an insufficiently
sized buffer, we should report it to the guest as the kernel
does and don't log anything
Rewrite the parts of the function that deal with length to
fix these issues, and add a comment in target_to_host_cmsg
to explain why the overflow logging it does is a QEMU bug,
not a guest issue.

target-arm: Correct "preferred return address" for cpreg access exceptions
The architecture defines that when taking an exception trying to
access a coprocessor register, the "preferred return address" for
the exception is the address of the instruction that caused the
exception. Correct an off-by-4 error which meant we were returning
the address after the instruction for traps which happened because
of a failure of a runtime access-check function on an AArch32
register. (Traps caused by translate-time checkable permissions
failures had the correct address, as did traps on AArch64 registers.)

arm: Add has-mpu property
For processors that support MPUs, add a property to de-feature it. This
is similar to the implementation of the EL3 feature.
The processor definition in init sets ARM_FEATURE_MPU if it can support
an MPU. post_init exposes the property, defaulting to true. If cleared
by the instantiator, ARM_FEATURE_MPU is then removed at realize time.
This is to support R profile processors that may or may-not have an MPU
configured.

target-arm: Use the kernel's idea of MPIDR if we're using KVM
When we're using KVM, the kernel's internal idea of the MPIDR
affinity fields must match the values we tell it for the guest
vcpu cluster configuration in the device tree. Since at the moment
the kernel doesn't support letting userspace tell it the correct
affinity fields to use, we must read the kernel's view and
reflect that back in the device tree.

target-arm: Handle "extended small page" descriptors correctly
The old ARMv5-style page table format includes a kind of second level
descriptor named the "extended small page" format, whose primary purpose
is to allow specification of the TEX memory attribute bits on a 4K page.
This exists on ARMv6 and also (as an implementation extension) on XScale
CPUs; it's UNPREDICTABLE on v5.
We were mishandling this in two ways:
(1) we weren't implementing it for v6 (probably never noticed because
Linux will use the new-style v6 page table format there)
(2) we were not correctly setting the page_size, which is 4K, not 1K
The latter bug went unnoticed for years because the only thing which
the page_size affects is which TLB entries get flushed when the guest
does a TLB invalidate on an address in the page, and prior to commit
2f0d8631b7 we were doing a full TLB flush very frequently due to Linux's
habit of writing the SCTLR pointlessly a lot.
(We can assume that after commit 2f0d8631b7 the bug went unnoticed
for a year because nobody's actually using the Zaurus/XScale emulation...)
Report the correct page size for these descriptors, and permit them
on ARMv6 CPUs. This fixes a problem where a kernel image for Zaurus
can boot the kernel OK but gets random segfaults when it tries to
run userspace programs.

s390/bios: build with -fdelete-null-pointer-checks
Starting with version 4.9, GCC assumes it can't safely dereference null
pointers, and uses this for some optimizations. On s390, the lowcore
memory is located at address 0, so this assumption is wrong and breaks
the s390-ccw firmware. Pass -fdelete-null-pointer-checks to avoid that.

dsoundaudio: remove primary buffer
Enabling this option just creates a playback buffer with the specified settings,
and then ignores it. It's probably some outdated hack to set audio formats on
windows. (The first created stream dictates all other streams settings, at least
on some Windows versions). Setting DAC_FIXED_SETTINGS should have the same
effect as setting (the now removed) primary buffer.

According to MSDN this may happen when the window is not in the foreground, but

audio: expose drv_opaque to init_out and init_in
Currently the opaque pointer returned by audio_driver's init is only
exposed to the driver's fini, but not to audio_pcm_ops. This way if
someone wants to share a variable with the driver and the pcm, he must
use global variables. This patch fixes it by adding a third parameter to
audio_pcm_op's init_out and init_in.

linux-user: Allocate thunk size dynamically
We store all struct types in an array of static size without ever
checking whether we overrun it. Of course some day someone (like me
in another, ancient ALSA enabling patch set) will run into the limit
without realizing it.
So let's make the allocation dynamic. We already know the number of
structs that we want to allocate, so we only need to pass the variable
into the respective piece of code.
Also, to ensure we don't accidently overwrite random memory, add some
asserts to sanity check whether a thunk is actually part of our array.

block: Fix reopen flag inheritance
When reopening an image, the block layer already takes care to reopen
bs->file as well with recalculated inherited flags. The same must happen
for any other child (most notably missing before this patch: backing
files).
If bs->file (or any other child) didn't originally inherit from bs, e.g.
because it was created separately and then only referenced, it must not
inherit flags on reopen either, so check the inherited_from field before
propagation the reopen down.
VMDK already reopened its extents manually; this code can now be
dropped.

block: Add BlockDriverState.inherits_from
Currently, the block layer assumes that any block node can have only one
parent, and if it has a parent, that it inherits some options/flags from
this parent.
This is not true any more: With references used in block device
creation, a single node can be used by multiple parents, or it can be
created separately and not inherit flags from any parent.
To handle reopens correctly, a node must know from which parent it
inherited options. This patch adds the information to BlockDriverState.

block: Add list of children to BlockDriverState
This allows iterating over all children of a given BDS, not only
including bs->file and bs->backing_hd, but also driver-specific
ones like VMDK extents or Quorum children.
For bdrv_swap(), the list of children of the swapped BDS stays at that
BDS (because that's where the pointers stay as well). The list head
moves and pointers to it must be fixed up therefore.
The list of children in the parent of the swapped BDS is not affected by
the swap. The contents of the BDS objects is swapped, so the existing
pointer in the parent automatically points to the newly swapped in BDS.

block: Drain requests before swapping nodes in bdrv_swap()
bdrv_swap() requires that there are no requests in flight on either of
the two devices. The request coroutine would work on the wrong
BlockDriverState object (with bs->opaque even being interpreted as a
different type potentially) and all sorts of bad things would result
from this.
The currently existing callers mostly ensure that there is no I/O
pending on nodes that are swapped. In detail, this is:
1. Live snapshots. This goes through qmp_transaction(), which calls
bdrv_drain_all() before doing anything. The command is executed
synchronously, so no new I/O can be issued concurrently.
2. snapshot=on in bdrv_open(). We're in the middle of opening the image
(both the original image and its temporary overlay), so there can't
be any I/O in flight yet.
3. Mirroring. bdrv_drain() is already used on the source device so that
the mirror doesn't miss anything. However, the main loop runs between
that and the bdrv_swap() (which is actually a bug, being addressed in
another series), so there is a small window in which new I/O might be
issued that would be in flight during bdrv_swap().
It is safer to just drain the request queue of both devices in
bdrv_swap() instead of relying on callers to do the right thing.

block: driver should override flags in bdrv_open()
The BDRV_O_PROTOCOL flag should have an impact only if no driver is
specified explicitly. Therefore, if bdrv_open() is called with an
explicit block driver argument (either through the options QDict or
through the drv parameter) and that block driver is a protocol block
driver, BDRV_O_PROTOCOL should be set; if it is a format block driver,
BDRV_O_PROTOCOL should be unset.
While there was code to unset the flag in case a format block driver
has been selected, it only followed the bdrv_fill_options() function
call whereas the flag in fact needs to be adjusted before it is used
there.
With that change, BDRV_O_PROTOCOL will always be set if the BDS should
be a protocol driver; if the driver has been specified explicitly, the
new code will set it; and bdrv_fill_options() will only "probe" a
protocol driver if BDRV_O_PROTOCOL is set. The probing after
bdrv_fill_options() cannot select a protocol driver.
Thus, bdrv_open_image() to open BDS.file is never called if a protocol
BDS is about to be created. With that change in turn it is impossible to
call bdrv_open_common() with a protocol drv and file != NULL, which
allows us to remove the bdrv_swap() call.
This change breaks a test case in qemu-iotest 051:
"-drive file=t.qcow2,file.driver=qcow2" now works because the explicitly
specified "qcow2" overrides the BDRV_O_PROTOCOL which is automatically
set for the "file" BDS (and the filename is just passed down).
Therefore, this patch removes that test case.

raw-posix: Fix .bdrv_co_get_block_status() for unaligned image size
Image files with an unaligned image size have a final hole that starts
at EOF, i.e. in the middle of a sector. Currently, *pnum == 0 is
returned when checking the status of this sector. In qemu-img, this
triggers an assertion failure.
In order to fix this, one type for the sector that contains EOF must be
found. Treating a hole as data is safe, so this patch rounds the
calculated number of data sectors up, so that a partial sector at EOF is
treated as a full data sector.

qemu-iotests: expand test 093 to support group throttling
This patch improves the test by attaching a different number of drives
to the VM and putting them in the same throttling group. The test
verifies that the I/O is evenly distributed among all members of the
group, and that the limits are enforced.
By default the test is repeated 3 times with 1, 2 and 3 drives, but
the maximum number of simultaneous drives is configurable.

bdrv_swap() touches the fields of a BlockDriverState that are

their original place, they are temporarily swapped in the process,
so there's a chance that an operation on a member of the same group
happening on a different thread can try to use them.

throttle: Add throttle group support
The throttle group support use a cooperative round robin scheduling
algorithm.
The principles of the algorithm are simple:
- Each BDS of the group is used as a token in a circular way.
- The active BDS computes if a wait must be done and arms the right
timer.
- If a wait must be done the token timer will be armed so the token
will become the next active BDS.

raw-posix: Fix .bdrv_co_get_block_status() for unaligned image size
Image files with an unaligned image size have a final hole that starts
at EOF, i.e. in the middle of a sector. Currently, *pnum == 0 is
returned when checking the status of this sector. In qemu-img, this
triggers an assertion failure.
In order to fix this, one type for the sector that contains EOF must be
found. Treating a hole as data is safe, so this patch rounds the
calculated number of data sectors up, so that a partial sector at EOF is
treated as a full data sector.
This fixes https://bugzilla.redhat.com/show_bug.cgi?id=1229394

rocker: bring link up/down on PHY enable/disable
When the OS driver enables/disables the port, go ahead and set the port's
link status to up/down in response to the change. This more closely
emulates real hardware when the PHY for the port is brought up/down
and the PHY negotiates carrier (link status) with link partner. In
the case of qemu, the virtual rocker device can't really do link
negotiation with the link partner as that requires signally over a
physical medium (the wire), so just pretend the negotiation was
successful and bring the link up when the port is enabled.

false, the fd will not be polled in this iteration.
This is redundant with checks inside read callback. After this patch,
the data will be sent to peer when it arrives. If the device can't
receive, it will be queued to incoming_queue, and when the device status

target-mips: add MTHC0 and MFHC0 instructions
Implement MTHC0 and MFHC0 instructions. In MIPS32 they are used to access
upper word of extended to 64-bits CP0 registers.
In MIPS64, when CP0 destination register specified is the EntryLo0 or
EntryLo1, bits 1:0 of the GPR appear at bits 31:30 of EntryLo0 or
EntryLo1. This is to compensate for RI and XI, which were shifted to bits
63:62 by MTC0 to EntryLo0 or EntryLo1. Therefore creating separate
functions for EntryLo0 and EntryLo1.

target-mips: add CP0.PageGrain.ELPA support
CP0.PageGrain.ELPA enables support for large physical addresses. This field
is encoded as follows:
0: Large physical address support is disabled.
1: Large physical address support is enabled.
If this bit is a 1, the following changes occur to coprocessor 0 registers:
- The PFNX field of the EntryLo0 and EntryLo1 registers is writable and
concatenated with the PFN field to form the full page frame number.
- Access to optional COP0 registers with PA extension, LLAddr, TagLo is
defined.
P5600 can operate in 32-bit or 40-bit Physical Address Mode. Therefore if
XPA is disabled (CP0.PageGrain.ELPA = 0) then assume 32-bit Address Mode.
In MIPS64 assume 36 as default PABITS (when CP0.PageGrain.ELPA = 0).
env->PABITS value is constant and indicates maximum PABITS available on
a core, whereas env->PAMask is calculated from env->PABITS and is also
affected by CP0.PageGrain.ELPA.

Add a protective section footer
Badly formatted migration streams can go undetected or produce
misleading errors due to a lock of checking at the end of sections.
In particular a section that adds an extra 0x00 at the end
causes what looks like a normal end of stream and thus doesn't produce
any errors, and something that ends in a 0x01..0x04 kind of look
like real section headers and then fail when the section parser tries
to figure out which section they are. This is made worse by the
choice of 0x00..0x04 being small numbers that are particularly common
in normal section data.
This patch adds a section footer consisting of a marker (0x7e - ~)
followed by the section-id that was also sent in the header. If
they mismatch then it throws an error explaining which section was
being loaded.

optional subsections. Instead of having two mechanism that do the
same, we can just generalize it.
For subsections we just change:
- Add a needed function to VMStateDescription
- Remove VMStateSubsection (after removal of the needed function
it is just a VMStateDescription)
- Adjust the whole tree, moving the needed function to the corresponding

i386/acpi-build: fix PXB workarounds for unsupported BIOSes
The patch
apci: fix PXB behaviour if used with unsupported BIOS
uses the following condition to see if a "PXB mem/IO chunk" has *not* been
configured by the BIOS:
(!range_base || range_base > range_limit)
When this condition evaluates to true, said patch *omits* the
corresponding entry from the _CRS.
Later on the patch checks for the opposite condition (with the intent of
*adding* entries to the _CRS if the "PXB mem/IO chunks" *have* been
configured). Unfortunately, the condition was negated incorrectly: only
the first ! operator was removed, which led to the nonsensical expression
(range_base || range_base > range_limit)
leading to bogus entries in the _CRS, and causing BSOD in Windows Server
2012 R2 when it runs on OVMF.
The correct negative of the condition seen at the top is
(range_base && range_base <= range_limit)
Fix the expressions.

i386/acpi-build: more traditional _UID and _HID for PXB root buses
The ACPI specification permits the _HID and _UID objects to evaluate to
strings. (See "6.1.5 _HID (Hardware ID)" and "6.1.12 _UID (Unique ID)" in
the ACPI v6.0 spec.)
With regard to related standards, the UEFI specification can also express
a device address composed from string _HID and _UID identifiers, inside
the Expanded ACPI Device Path Node. (See "9.3.3 ACPI Device Path", Table
49, in the UEFI v2.5 spec.)
However, numeric (integer) contents for both _HID and _UID are more
traditional. They are recommended by the UEFI spec for size reasons:
[...] the ACPI Device Path node is smaller and should be used if
possible to reduce the size of device paths that may potentially be
stored in nonvolatile storage [...]
External tools support them better (for example the --acpi_hid and
--acpi_uid options of "efibootmgr" only take numeric identifiers).
Finally, numeric _HID and _UID contents are existing practice in the QEMU
source.
This patch was tested with a Fedora 20 LiveCD and a preexistent Windows
Server 2012 R2 guest. Using "acpidump" and "iasl" in the Fedora guest, we
get, in the SSDT:
> Scope (\_SB)
> {
> Device (PC04)
> {
> Name (_UID, 0x04) // _UID: Unique ID
> Name (_HID, EisaId ("PNP0A03") /* PCI Bus */) // _HID: Hardware ID

target-mips: add ERETNC instruction and Config5.LLB bit
ERETNC is identical to ERET except that an ERETNC will not clear the LLbit
that is set by execution of an LL instruction, and thus when placed between
an LL and SC sequence, will never cause the SC to fail.
Presence of ERETNC is denoted by the Config5.LLB.

target-mips: Misaligned memory accesses for MSA
MIPS SIMD Architecture vector loads and stores require misalignment support.
MSA Memory access should work as an atomic operation. Therefore, it has to
check validity of all addresses for a vector store access if it is spanning
into two pages.
Separating helper functions for each data format as format is known in
translation.
To use mmu_idx from cpu_mmu_index() instead of calculating it from hflag.
Removing save_cpu_state() call in translation because it is able to use
cpu_restore_state() on fault as GETRA() is passed.

mips_malta: provide ememsize env variable to kernels
Commit 94c2b6aff43c (mips_malta: support up to 2GiB RAM) provided
support for using over 256MB of RAM with the MIPS Malta board, including
capping the memsize variable that QEMUs pseudo-bootloader provides to
the kernel at 256MB in order to match YAMON. It didn't however provide
the ememsize variable which kernels supporting memory outside of the
unmapped address spaces (ie. EVA or highmem) may use to determine the
true size of the RAM present in the system.
Set ememsize to the size of RAM so that such kernels may use all
available memory without the user having to manually specifying its size
& location.

virtio-pci: correctly set host notifiers for modern bar
Currently, during host notifier set. We only add eventfd for legacy
bar, this is not correct since:
- Non-transitional device does not have legacy bar, so qemu will crash
since proxy->bar was not initialized.
- Modern device uses modern bar and notify cap to notify the device,
we should add eventfd for proxy->notify.
So this patch fixes the above two issues by adding eventfd based on
whether legacy or modern device were supported.

Add API for transports to execute word/dword accesses in

pcnet: force the buffer access to be in bounds during tx
4096 is the maximum length per TMD and it is also currently the size of
the relay buffer pcnet driver uses for sending the packet data to QEMU
for further processing. With packet spanning multiple TMDs it can
happen that the overall packet size will be bigger than sizeof(buffer),
which results in memory corruption.
Fix this by only allowing to queue maximum sizeof(buffer) bytes.
This is CVE-2015-3209.
[Fixed 3-space indentation to QEMU's 4-space coding standard.

bios-tables-test: handle false-positive smbios signature matches
It has been reported that sometimes the .rodata section of SeaBIOS,
containing the constant string against which the SMBIOS signature
ends up being compared, also falls within the guest f-segment. In
that case, the test obviously fails, unless we continue searching
for the *real* SMBIOS entry point.
Rather than stopping at the first match for the SMBIOS signature
("_SM_") in the f-segment (0xF0000-0xFFFFF), continue scanning
until either a valid entry point table is found, or the f-segment
has been exhausted.

fw_cfg: remove support for guest-side data writes
From this point forward, any guest-side writes to the fw_cfg
data register will be treated as no-ops. This patch also removes
the unused host-side API function fw_cfg_add_callback(), which
allowed the registration of a callback to be executed each time
the guest completed a full overwrite of a given fw_cfg data item.

fw_cfg: fix FW_CFG_BOOT_DEVICE update on ppc and sparc
On ppc, sparc, and sparc64, the value of the FW_CFG_BOOT_DEVICE 16bit
fw_cfg entry is repeatedly modified from a series of callbacks, which
currently results in the previous value's dynamically allocated memory
being leaked.
This patch switches updating to the new fw_cfg_modify_i16() call, which
does not cause memory leaks.

tcg: fix dead computation for repeated input arguments
When the same temp is used twice or more as an input argument to a TCG
instruction, the dead computation code doesn't recognize the second use
as a dead temp. This is because the temp is marked as live in the same
loop where dead inputs are checked.
The fix is to split the loop in two parts. This avoid emitting a move
and using a register for the movcond instruction when used as "move if
true" on x86-64. This might bring more improvements on RISC TCG targets
which don't have outputs aliased to inputs.

tcg: fix register allocation with two aliased dead inputs
For TCG ops with two outputs registers (add2, sub2, div2, div2u), when
the same input temp is used for the two inputs aliased to the two
outputs, and when these inputs are both dead, the register allocation
code wrongly assigned the same register to the same output.
This happens for example with sub2 t1, t2, t3, t3, t4, t5, when t3 is
not used anymore after the TCG op. In that case the same register is
used for t1, t2 and t3.
The fix is to look for already allocated aliased input when allocating
a dead aliased input and check that the register is not already
used.

sdl2: fix crash in handle_windowevent() when restoring the screen size
The Ctrl-Alt-u keyboard shortcut restores the screen to its original
size. In the SDL2 UI this is done by destroying the window and
creating a new one. The old window emits SDL_WINDOWEVENT_HIDDEN when
it's destroyed, but trying to call SDL_GetWindowFromID() from that
event's window ID returns a null pointer. handle_windowevent() assumes
that the pointer is never null so it results in a crash.

vhost-user: Improve -netdev/netdev_add/-net/... error reporting
When -netdev vhost-user fails, it first reports a specific error, then
one or more generic ones, like this:
$ qemu-system-x86_64 -netdev vhost-user,id=foo,chardev=xxx
qemu-system-x86_64: -netdev vhost-user,id=foo,chardev=xxx: chardev "xxx" not found
qemu-system-x86_64: -netdev vhost-user,id=foo,chardev=xxx: No suitable chardev found
qemu-system-x86_64: -netdev vhost-user,id=foo,chardev=xxx: Device 'vhost-user' could not be initialized
With the command line, the messages go to stderr. In HMP, they go to
the monitor. In QMP, the last one becomes the error reply, and the
others go to stderr.
Convert net_init_vhost_user() and its helpers to Error. This
suppresses the unwanted unspecific error messages, and makes the
specific error the QMP error reply.

vl: Fail right after first bad -object
Failure to create an object with -object is a fatal error. However,
we delay the actual exit until all -object are processed. On the one
hand, this permits detection of genuine additional errors. On the
other hand, it can muddy the waters with uninteresting additional
errors, e.g. when a later -object tries to reference a prior one that
failed.
We generally stop right on the first bad option, so do that for
-object as well.

machine: Drop use of DEFAULT_RAM_SIZE in help text
As of commit 076b35b5a (machine: add default_ram_size to machine
class) we no longer have a global default ram size, but instead
machine specific defaults. When invoking qemu --help we don't know
which machine you selected, so we can't tell the user the default RAM
size in the help text anymore now.
Thus I don't see an easy way to expose the default ram size to the
user in the help text. The easiest option IMHO is to just drop this
piece of information.

monitor: Fix QMP ABI breakage around "id"
Commit 65207c5 accidentally dropped a line of code we need along with
a comment that became wrong then. This made QMP reject "id":
{"execute": "system_reset", "id": "1"}
{"error": {"class": "GenericError", "desc": "QMP input object member 'id' is unexpected"}}
Put the lost line right back, so QMP again accepts and returns "id",
as promised by the ABI:
{"execute": "system_reset", "id": "1"}
{"return": {}, "id": "1"}

atomics: add explicit compiler fence in __atomic memory barriers
__atomic_thread_fence does not include a compiler barrier; in the
C++11 memory model, fences take effect in combination with other
atomic operations. GCC implements this by making __atomic_load and
__atomic_store access memory as if the pointer was volatile, and
leaves no trace whatsoever of acquire and release fences in the
compiler's intermediate representation.
In QEMU, we want memory barriers to act on all memory, but at the same
time we would like to use __atomic_thread_fence for portability reasons.
Add compiler barriers manually around the __atomic_thread_fence.

q35: implement SMRAM.D_LCK
Once the SMRAM.D_LCK bit has been set by the guest several bits in SMRAM
and ESMRAMC become readonly until the next machine reset. Implement
this by updating the wmask accordingly when the guest sets the lock bit.
As the lock it itself is locked down too we don't need to worry about
the guest clearing the lock bit.

q35: implement high SMRAM
When H_SMRAME is 1, low memory at 0xa0000 is left alone by
SMM, and instead the chipset maps the 0xa0000-0xbffff window at
0xfeda0000-0xfedbffff. This affects both the "non-SMM" view controlled
by D_OPEN and the SMM view controlled by G_SMRAME, so add two new
MemoryRegions and toggle the enabled/disabled state of all four
in mch_update_smram.

hw/i386: add a separate region that tracks the SMRAME bit
This region is exported at /machine/smram. It is "empty" if
SMRAME=0 and points to SMRAM if SMRAME=1. The CPU will
enable/disable it as it enters or exits SMRAM.
While touching nearby code, the existing memory region setup was
slightly inconsistent. The smram_region is *disabled* in order to open
SMRAM (because the smram_region shows the low VRAM instead of the RAM
at 0xa0000). Because SMRAM is closed at startup, the smram_region must
be enabled when creating the i440fx or q35 devices.

vl: allow full-blown QemuOpts syntax for -global
-global does not work for drivers that have a dot in their name, such as
cfi.pflash01. This is just a parsing limitation, because such globals
can be declared easily inside a -readconfig file.
To allow this usage, support the full QemuOpts key/value syntax for -global
too, for example "-global driver=cfi.pflash01,property=secure,value=on".
The two formats do not conflict, because the key/value syntax does not have
a period before the first equal sign.

target-i386: mask NMIs on entry to SMM
QEMU is not blocking NMIs on entry to SMM. Implementing this has to
cover a few corner cases, because:
- NMIs can then be enabled by an IRET instruction and there
is no mechanism to _set_ the "NMIs masked" flag on exit from SMM:
"A special case can occur if an SMI handler nests inside an NMI handler
and then another NMI occurs. [...] When the processor enters SMM while
executing an NMI handler, the processor saves the SMRAM state save map
but does not save the attribute to keep NMI interrupts disabled.
- However, there is some hidden state, because "If NMIs were blocked
before the SMI occurred [and no IRET is executed while in SMM], they
are blocked after execution of RSM." This is represented by the new
HF2_SMM_INSIDE_NMI_MASK bit. If it is zero, NMIs are _unblocked_
on exit from RSM.

memory: use mr->ram_addr in "is this RAM?" assertions
mr->terminates alone doesn't guarantee that we are looking at a RAM region.
mr->ram_addr also has to be checked, in order to distinguish RAM and I/O
regions.
So, do the following:
1) add a new define RAM_ADDR_INVALID, and test it in the assertions
instead of mr->terminates
2) IOMMU regions were not setting mr->ram_addr to a bogus value, initialize
it in the instance_init function so that the new assertions would fire
for IOMMU regions as well.

bitmap: add atomic set functions
Use atomic_or() for atomic bitmaps where several threads may set bits at

When setting all bits in a word we can avoid atomic ops and instead just
use an smp_mb() at the end.
Most bitmap users don't need atomicity so introduce new functions.

exec: only check relevant bitmaps for cleanliness
Most of the time, not all bitmaps have to be marked as dirty;
do not do anything if the interesting ones are already dirty.
Previously, any clean bitmap would have cause all the bitmaps to be
marked dirty.
In fact, unless running TCG most of the time bitmap operations need
not be done at all, because memory_region_is_logging returns zero.
In this case, skip the call to cpu_physical_memory_range_includes_clean
altogether as well.
With this patch, cpu_physical_memory_set_dirty_range is called
unconditionally, so there need not be anymore a separate call to

exec: invert return value of cpu_physical_memory_get_clean, rename
While it is obvious that cpu_physical_memory_get_dirty returns true even if
a single page is dirty, the same is not true for cpu_physical_memory_get_clean;
one would expect that it returns true only if all the pages are clean, but
it actually looks for even one clean page. (By contrast, the caller of that
function, cpu_physical_memory_range_includes_clean, has a good name).
To clarify, rename the function to cpu_physical_memory_all_dirty and return
true if _all_ the pages are dirty. This is the opposite of the previous
meaning, because "all are 1" is the same as "not (any is 0)", so we have to
modify cpu_physical_memory_range_includes_clean as well.

translate-all: make less of tb_invalidate_phys_page_range depend on is_cpu_write_access
is_cpu_write_access is only set if tb_invalidate_phys_page_range is called
from tb_invalidate_phys_page_fast, and hence from notdirty_mem_write.
However:
- the code bitmap can be built directly in tb_invalidate_phys_page_fast
(unconditionally, since is_cpu_write_access would always be passed as 1);
- the virtual address is not needed to mark the page as "not containing
code" (dirty code bitmap = 1), so we can also remove that use of
is_cpu_write_access. For calls of tb_invalidate_phys_page_range
that do not come from notdirty_mem_write, the next call to
notdirty_mem_write will notice that the page does not contain code
anymore, and will fix up the TLB entry.
The parameter needs to remain in order to guard accesses to cpu->mem_io_pc.

exec: use memory_region_get_dirty_log_mask to optimize dirty tracking
The memory API can now return the exact set of bitmaps that have to
be tracked. Use it instead of the in_migration variable.
In the next patches, we will also use it to set only DIRTY_MEMORY_VGA
or DIRTY_MEMORY_MIGRATION if necessary. This can make a difference
for dataplane, especially after the dirty bitmap is changed to use
more expensive atomic operations.
Of some interest is the change to stl_phys_notdirty. When migration
was introduced, stl_phys_notdirty was changed to effectively behave
as stl_phys during migration. In fact, if one looks at the function as it
was in the beginning (commit 8df1cd0, physical memory access functions,
2005-01-28), at the time the dirty bitmap was the equivalent of
DIRTY_MEMORY_CODE nowadays; hence, the function simply should not touch
the dirty code bits. This patch changes it to do the intended thing.

memory: include DIRTY_MEMORY_MIGRATION in the dirty log mask
The separate handling of DIRTY_MEMORY_MIGRATION, which does not
call log_start/log_stop callbacks when it changes in a region's
dirty logging mask, has caused several bugs.
One recent example is commit 4cc856f (kvm-all: Sync dirty-bitmap from
kvm before kvm destroy the corresponding dirty_bitmap, 2015-04-02).
Another performance problem is that KVM keeps tracking dirty pages
after a failed live migration, which causes bad performance due to
disallowing huge page mapping.
This patch removes the root cause of the problem by reporting
DIRTY_MEMORY_MIGRATION changes via log_start and log_stop.
Note that we now have to rebuild the FlatView when global dirty
logging is enabled or disabled; this ensures that log_start and
log_stop callbacks are invoked.
This will also be used to make the setting of bitmaps conditional.
In general, this patch lets users of the memory API ignore the
global state of dirty logging if they handle dirty logging
generically per region.

memory: prepare for multiple bits in the dirty log mask
When the dirty log mask will also cover other bits than DIRTY_MEMORY_VGA,
some listeners may be interested in the overall zero/non-zero value of
the dirty log mask; others may be interested in the value of single bits.
For this reason, always call log_start/log_stop if bits have respectively
appeared or disappeared, and pass the old and new values of the dirty log
mask so that listeners can distinguish the kinds of change.
For example, KVM checks if dirty logging used to be completely disabled
(in log_start) or is now completely disabled (in log_stop). On the
other hand, Xen has to check manually if DIRTY_MEMORY_VGA changed,
since that is the only bit it cares about.

in two functions: one that returns a given bit from dirty_log_mask,
and one that returns the entire mask. memory_region_is_logging gets an
extra parameter so that the compiler flags misuse.
While VGA-specific users (including the Xen listener!) will want to keep
checking that bit, KVM and vhost check for "any bit except migration"
(because migration is handled via the global start/stop listener
callbacks).

Makefile.target: set master BUILD_DIR
make can be invoked in the individual build dirs to build an individual
target or just a single file of a target. e.g.
touch translate-all.c
make -C microblazeel-softmmu translate-all.o
There is however a small bug when using the pixman submodule.
config-host.mak will ref BUILD_DIR for the pixman -I CFLAGS:
grep BUILD_DIR config-host.mak
QEMU_CFLAGS=-I$(SRC_PATH)/pixman/pixman -I$(BUILD_DIR)/pixman/pixman ...
This causes a build failure as -I/pixman/pixman (BUILD_DIR=="") will
not be found.
BUILD_DIR is usually set by the top level Makefile. Just lazy-set it in
Makefile.target to the parent directory.
Granted, this will not work if the pixman submodule is not prebuilt,
but it at least means you can do incremental partial builds once you
have done your initial full build (or attempt) from the top level.
The next step would be refactor make infrastructure to rebuild pixman
on a submake like the one above.

small memcpys like this one are special-cased anyway, and optimized

In particular, this fixes a bug whereby chains of overlapping head/tail chains
would incorrectly write over each other's remainder cache. This is the access

While we are here, rename the DBDMA_io struct property remainder to

target-s390x: Only access allocated storage keys

target-s390x: fix MVC instruction when areas overlap
The MVC instruction and the memmove C funtion do not have the same
semantic when memory areas overlap:
MVC: When the operands overlap, the result is obtained as if the
operands were processed one byte at a time and each result byte were
stored immediately after fetching the necessary operand byte.
memmove: Copying takes place as though the bytes in src are first copied
into a temporary array that does not overlap src or dest, and the bytes
are then copied from the temporary array to dest.
The behaviour is therefore the same when the destination is at a lower
address than the source, but not in the other case. This is actually a
trick for propagating a value to an area. While the current code detects
that and call memset in that case, it only does for 1-byte value. This
trick can and is used for propagating two or more bytes to an area.
In the softmmu case, the call to mvc_fast_memmove is correct as the
above tests verify that source and destination are each within a page,
and both in a different page. The part doing the move 8 bytes by 8 bytes
is wrong and we need to check that if the source and destination
overlap, they do with a distance of minimum 8 bytes before copying 8
bytes at a time.
In the user code, we should check check that the destination is at a
lower address than source or than the end of the source is at a lower
address than the destination before calling memmove. In the opposite
case we fallback to the same code as the softmmu one. Note that l
represents (length - 1).

target-s390x: use softmmu functions for mvcp/mvcs
mvcp and mvcs helper get access to the physical memory by a call to
mmu_translate for the virtual to real conversion and then using ldb_phys
and stb_phys to physically access the data. In practice this is quite
slow because it bypasses the QEMU softmmu TLB and because stb_phys calls
try to invalidate the corresponding memory for each access.
Instead use cpu_ldb_{primary,secondary} for the loads and
cpu_stb_{primary,secondary} for the stores. Ideally this should be
further optimized by a call to memcpy, but that already improves the
boot time of a guest by a factor 1.8.

target-s390x: fix MMU index computation
The cpu_mmu_index function wrongly looks at PSW P bit to determine the
MMU index, while this bit actually only control the use of priviledge
instructions. The addressing mode is detected by looking at the PSW ASC
bits instead.
This used to work more or less correctly up to kernel 3.6 as the kernel
was running in primary space and userland in secondary space. Since
kernel 3.7 the default is to run the kernel in home space and userland
in primary space. While the current QEMU code seems to work it open some
security issues, like accessing the lowcore memory in R/W mode from a
userspace process once it has been accessed by the kernel (it is then
cached by the QEMU TLB).
At the same time change the MMU_USER_IDX value so that it matches the
value used in recent kernels.

target-s390x: fix LOAD MULTIPLE instruction on page boundary
When consecutive memory locations are on page boundary a page fault
might occur when using the LOAD MULTIPLE instruction. In that case real
hardware doesn't load any register.
This is an important detail in case the base register is in the list
of registers to be loaded. If a page fault occurs this register might be
overwritten and when the instruction is later restarted the wrong
base register value is useD.
Fix this by first loading the first and last value from memory, hence
triggering all possible page faults, and then the remaining registers.
This fixes random segmentation faults seen in the guest.

target-s390x: fix CC computation for LOAD POSITIVE instructions
LOAD POSITIVE instructions (LPR, LPGR and LPGFR) set the following
condition code:
0: Result zero; no overflow
1: --
2: Result greater than zero; no overflow
3: Overflow
The current code wrongly returns 1 instead of 2 in case of a result
greater than 0. This patches fixes that. This fixes the marshalling of
the value '0L' in Python.

target-s390x: fix CC computation for EX instruction
Commit 7a6c7067f optimized CC computation by only saving cc_op before
calling helpers as they either don't touch the CC or generate a new
static value. This however doesn't work for the EX instruction as the
helper changes or not the CC value depending on the actual executed
instruction (e.g. MVC vs CLC).
This patches force a CC computation before calling the helper. This
fixes random memory corruption occuring in guests.

vhost: logs sharing
Currently we allocate one vhost log per vhost device. This is sub
optimal when:
- Guest has several device with vhost as backend
- Guest has multiqueue devices
In the above cases, we can avoid the memory allocation by sharing a
single vhost log among all the vhost devices. This is done through:
- Introducing a new vhost_log structure with refcnt inside.
- Using a global pointer to vhost_log structure that will be used. And
introduce helper to get the log with expected log size and helper to
- drop the refcnt to the old log.
- Each vhost device still keep track of a pointer to the log that was
used.
With above, if no resize happens, all vhost device will share a single
vhost log. During resize, a new vhost_log structure will be allocated
and made for the global pointer. And each vhost devices will drop the
refcnt to the old log.
Tested by doing scp during migration for a 2 queues virtio-net-pci.

hw/acpi: piix4_pm_init(): take fw_cfg object no more
This PIIX4 init function has no more reason to receive a pointer to the
FwCfg object. Remove the parameter from the prototype, and update callers.
As a result, the pc_init1() function no longer needs to save the return
value of pc_memory_init() and xen_load_linux(), which makes it more
similar to pc_q35_init().
The return type & value of pc_memory_init() and xen_load_linux() are not
changed themselves; maybe we'll need their return values sometime later.

hw/acpi: move "etc/system-states" fw_cfg file from PIIX4 to core
The acpi_pm1_cnt_init() core function is responsible for setting up the
register block that will ultimately react to S3 and S4 requests (see
acpi_pm1_cnt_write()). It makes sense to advertise this configuration to
the guest firmware via an easy to parse fw_cfg file (ACPI is too complex
for firmware to parse), and indeed PIIX4 does that. However, since
acpi_pm1_cnt_init() is not specific to PIIX4, neither should be the fw_cfg
file.
This patch makes "etc/system-states" appear on all chipsets modified in
the previous patch, not just PIIX4 (assuming they have fw_cfg at all).

pseries: Enable in-kernel H_LOGICAL_CI_{LOAD, STORE} implementations
qemu currently implements the hypercalls H_LOGICAL_CI_LOAD and
H_LOGICAL_CI_STORE as PAPR extensions. These are used by the SLOF firmware
for IO, because performing cache inhibited MMIO accesses with the MMU off
(real mode) is very awkward on POWER.
This approach breaks when SLOF needs to access IO devices implemented
within KVM instead of in qemu. The simplest example would be virtio-blk
using an iothread, because the iothread / dataplane mechanism relies on
an in-kernel implementation of the virtio queue notification MMIO.
To fix this, an in-kernel implementation of these hypercalls has been made,
(kernel commit 99342cf "kvmppc: Implement H_LOGICAL_CI_{LOAD,STORE} in KVM"
however, the hypercalls still need to be enabled from qemu. This performs
the necessary calls to do so.
It would be nice to provide some warning if we encounter a problematic
device with a kernel which doesn't support the new calls. Unfortunately,
I can't see a way to detect this case which won't either warn in far too
many cases that will probably work, or which is horribly invasive.

spapr_pci: emit hotplug add/remove events during hotplug
This uses extension of existing EPOW interrupt/event mechanism
to notify userspace tools like librtas/drmgr to handle
in-guest configuration/cleanup operations in response to
device_add/device_del.
Userspace tools that don't implement this extension will need
to be run manually in response/advance of device_add/device_del,
respectively.

spapr_pci: enable basic hotplug operations
This enables hotplug of PCI devices to a PHB. Upon hotplug we
generate the OF-nodes required by PAPR specification and
IEEE 1275-1994 "PCI Bus Binding to Open Firmware" for the
device.
We associate the corresponding FDT for these nodes with the DRC
corresponding to the slot, which will be fetched via
ibm,configure-connector RTAS calls by the guest as described by PAPR
specification.

We also set up device-tree properties in each PHBs initial FDT to

each PHB is DR-capable device with physical hotpluggable slots, each

This function handles generation of ibm,drc-* array device tree
properties to describe DRC topology to guests. This will by used

we associate with a particular DR Connector as part of
hotplug/unplug.
Since general management of boot-time device trees are handled

an FDT and offset. A mask of sPAPRDRConnector types is given to
instruct us on what types of connectors entries should be generated
for, since descriptions for different connectors may live in

spapr_events: event-scan RTAS interface
We don't actually rely on this interface to surface hotplug events, and
instead rely on the similar-but-interrupt-driven check-exception RTAS
interface used for EPOW events. However, the existence of this interface
is needed to ensure guest kernels initialize the event-reporting
interfaces which will in turn be used by userspace tools to handle these
events, so we implement this interface here.
Since events surfaced by this call are mutually exclusive to those
surfaced via check-exception, we also update the RTAS event queue code
to accept a boolean to mark/filter for events accordingly.
Events of this sort are not currently generated by QEMU, but the interface
has been tested by surfacing hotplug events via event-scan in place
of check-exception.

spapr_events: re-use EPOW event infrastructure for hotplug events
This extends the data structures currently used to report EPOW events to
guests via the check-exception RTAS interfaces to also include event types
for hotplug/unplug events.
This is currently undocumented and being finalized for inclusion in PAPR
specification, but we implement this here as an extension for guest
userspace tools to implement (existing guest kernels simply log these
events via a sysfs interface that's read by rtas_errd, and current
versions of rtas_errd/powerpc-utils already support the use of this
mechanism for initiating hotplug operations).
We also add support for queues of pending RTAS events, since in the
case of hotplug there's chance for multiple events being in-flight
at any point in time.

spapr_rtas: add ibm, configure-connector RTAS interface
This interface is used to fetch an OF device-tree nodes that describes a
newly-attached device to guest. It is called multiple times to walk the
device-tree node and fetch individual properties into a 'workarea'/buffer

The device-tree is generated by QEMU and passed to an sPAPRDRConnector during
the initial hotplug operation, and the state of these RTAS calls is tracked by
the sPAPRDRConnector. When the last of these properties is successfully
fetched, we report as special return value to the guest and transition
the device to a 'configured' state on the QEMU/DRC side.

spapr_drc: initial implementation of sPAPRDRConnector device
This device emulates a firmware abstraction used by pSeries guests to
manage hotplug/dynamic-reconfiguration of host-bridges, PCI devices,
memory, and CPUs. It is conceptually similar to an SHPC device,
complete with LED indicators to identify individual slots to physical
physical users and indicate when it is safe to remove a device. In
some cases it is also used to manage virtualized resources, such a
memory, CPUs, and physical-host bridges, which in the case of pSeries
guests are virtualized resources where the physical components are
managed by the host.
Guests communicate with these DR Connectors using RTAS calls,
generally by addressing the unique DRC index associated with a
particular connector for a particular resource. For introspection
purposes we expose this state initially as QOM properties, and
in subsequent patches will introduce the RTAS calls that make use of
it. This constitutes to the 'guest' interface.
On the QEMU side we provide an attach/detach interface to associate
or cleanup a DeviceState with a particular sPAPRDRConnector in
response to hotplug/unplug, respectively. This constitutes the
'physical' interface to the DR Connector.

hw/ppc/spapr: Fix error message when firmware could not be loaded
When specifying a non-existing file with the "-bios" parameter, QEMU
complained that it "could not find LPAR rtas". That's obviously a
copy-n-paste bug from the code which loads the spapr-rtas.bin, it
should complain about a missing firmware file instead.
Additionally the error message was printed with hw_error() - which
also dumps the whole CPU state. However, this does not make much
sense here since the CPU is not running yet and thus the registers
only contain zeroes. So let's use error_report() here instead.
And while we're at it, let's also bail out if the firmware file

(uval != -1), where 'uval' is an unsigned value.
This mostly works in practice, because as long as the width of uval is
greater or equal than that of (int), the -1 will be promoted to the
unsigned type, which is the expected outcome.
However, at least for the cases where uval is uint32_t, this would break
on platforms where sizeof(int) > 4 (and a few such do exist), because then
the uint32_t value would be promoted to the larger int type, and never be
equal to -1.
This patch fixes these errors. The fixes for the (uint32_t) cases are
necessary as described above. I've made similar fixes to (uint64_t) and
(hwaddr) cases. Those are strictly theoretical, since I don't know of any
platforms where sizeof(int) > 8, but hey, it's not that hard so we might
as well be strictly C standard compliant.

configure: Check for libfdt version 1.4.0
Some recent patches require a function from libfdt version 1.4.0,
so we should check for this version during the configure step
already. Unfortunately, there does not seem to be a proper #define
for the version number in the libfdt headers. So alternatively,
we check for the availability of the required function
fdt_get_property_by_offset() instead instead.

apci: fix PXB behaviour if used with unsupported BIOS
PXB does not work with unsupported bioses, but should

We don't ship them anymore, but it's reasonable
to keep the work-around until we update the bios in qemu.
Fix this by not adding PXB mem/IO chunks to _CRS
if they weren't configured by BIOS.

hw/pci: introduce PCI Expander Bridge (PXB)
PXB is a "light-weight" host bridge whose purpose is to enable
the main host bridge to support multiple PCI root buses
for pc machines.
As oposed to PCI-2-PCI bridge's secondary bus, PXB's bus
is a primary bus and can be associated with a NUMA node
(different from the main host bridge) allowing the guest OS
to recognize the proximity of a pass-through device to
other resources as RAM and CPUs.
The PXB is composed from:
- A primary PCI bus (can be associated with a NUMA node)
Acts like a normal pci bus and from the functionality point
of view is an "expansion" of the bus behind the
main host bridge.
- A pci-2-pci bridge behind the primary PCI bus where the actual
devices will be attached.
- A host-bridge PCI device
Situated on the bus behind the main host bridge, allows
the BIOS to configure the bus number and IO/mem resources.
It does not have its own config/data register for configuration
cycles, this being handled by the main host bridge.
- A host-bridge sysbus to comply with QEMU current design.

virtio-ccw/migration: Migrate config vector for virtio devices
virtio_ccw_{save|load}_config are missing code to save and restore a vdev's
config_vector value. This causes some virtio devices to become disabled
following a migration.
This patch fixes a bug whereby the qmp/hmp balloon command (virsh setmem)
silently fails to update the guest's available memory because the device was not
properly migrated.
This will break compatibility, but vmstate_s390_cpu was bumped from
version 2 to version 4 between v2.3.0 and v2.4.0 without a compat
handler. Furthermore, there is no production environment yet so
migration is fenced anyway between any relevant version of 2.3 and 2.4.

util: socket: Add missing localaddr and localport option for DGRAM socket
The 'socket_optslist' structure does not contain the 'localaddr' and
'localport' options that are parsed in case you are creating a
'connect' type UDP character device.
I've noticed it happening after commit f43e47dbf6de24db20ec9b588bb6cc762
made qemu abort() after seeing the invalid option.
A minimal reproducer for the case is:
$ qemu-system-x86_64 -chardev udp,id=charrng0,host=127.0.0.1,port=1234,localaddr=,localport=1234
qemu-system-x86_64: -chardev udp,id=charrng0,host=127.0.0.1,port=1234,localaddr=,localport=1234: Invalid parameter 'localaddr'
Aborted (core dumped)
Prior to the commit mentioned above the error would be printed but the
value for localaddr and localport was simply ignored. I did not go
through the code to find out when it was broken.
Add the two fields so that the options can again be parsed correctly and
qemu doesn't abort().

pc: Ensure non-zero CPU ref count after attaching to ICC bus
Setting the parent bus of a device increases its ref count, which we
ultimately want to level out. However it is only safe to do so after the
last reference to the device in local code, as qom-set or similar operations
might decrease the ref count.
Therefore move the object_unref() from pc_new_cpu() into its callers.
The APIC operations on the last CPU in pc_cpus_init() are still potentially
insecure, but that is beyond the scope of this code movement.

fdc: Fix MSR.RQM flag
The RQM bit in MSR should be set whenever the guest is supposed to
access the FIFO, and it should be cleared in all other cases. This is
important so the guest can't continue writing/reading the FIFO beyond
the length that it's suppossed to access (see CVE-2015-3456).
Commit e9077462 fixed the CVE by adding code that avoids the buffer
overflow; however it doesn't correct the wrong behaviour of the floppy
controller which should already have cleared RQM.
Currently, RQM stays set all the time and during all phases while a
command is being processed. This is error-prone because the command has
to explicitly clear the flag if it doesn't need data (and indeed, the
two buggy commands that are the culprits for the CVE just forgot to do
that).
This patch clears RQM immediately as soon as all bytes that are expected
have been received. If the the FIFO is used in the next phase, the flag
has to be set explicitly there.
It also clear RQM after receiving all bytes even if the phase transition
immediately sets it again. While it's technically not necessary at the
moment because the state between clearing and setting RQM is not
observable by the guest, this is more explicit and matches how real
hardware works. It will actually become necessary in qemu once
asynchronous code paths are introduced.
This alone should have been enough to fix the CVE, but now we have two
lines of defense - even better.

xen/MSI-X: limit error messages
Limit error messages resulting from bad guest behavior to avoid allowing
the guest to cause the control domain's disk to fill.
The first message in pci_msix_write() can simply be deleted, as this
is indeed bad guest behavior, but such out of bounds writes don't
really need to be logged.
The second one is more problematic, as there guest behavior may only
appear to be wrong: For one, the old logic didn't take the mask-all bit
into account. And then this shouldn't depend on host device state (i.e.
the host may have masked the entry without the guest having done so).
Plus these writes shouldn't be dropped even when an entry is unmasked.
Instead, if they can't be made take effect right away, they should take
effect on the next unmasking or enabling operation - the specification
explicitly describes such caching behavior. Until we can validly drop
the message (implementing such caching/latching behavior), issue the
message just once per MSI-X table entry.
Note that the log message in pci_msix_read() similar to the one being
removed here is not an issue: "addr" being of unsigned type, and the
maximum size of the MSI-X table being 32k, entry_nr simply can't be
negative and hence the conditonal guarding issuing of the message will
never be true.
This is XSA-130.

Data field with the high 16 bits not being covered by any known field).
Remove it and derive which fields not to write to from the accessed

doing any host write.

kvm: introduce kvm_arch_msi_data_to_gsi
On ARM the MSI data corresponds to the shared peripheral interrupt (SPI)
ID. This latter equals to the SPI index + 32. to retrieve the SPI index,
matching the gsi, an architecture specific function is introduced.

target-arm: Add the GICv2m to the virt board
Add a GICv2m device to the virt board to enable MSIs on the generic PCI
host controller. We allocate 64 SPIs in the IRQ space for now (this can
be increased/decreased later) and map the GICv2m right after the GIC in
the memory map.

target-arm: Extend the gic node properties
In preparation for adding the GICv2m which requires address specifiers
and is a subnode of the gic, we extend the gic DT definition to specify
the #address-cells and #size-cells properties and add an empty ranges
property properties of the DT node, since this is required to add the
v2m node as a child of the gic node.
Note that we must also expand the irq-map to reference the gic with the
right address-cells as a consequence of this change.

arm_gicv2m: Add GICv2m widget to support MSIs
The ARM GICv2m widget is a little device that handles MSI interrupt
writes to a trigger register and ties them to a range of interrupt lines
wires to the GIC. It has a few status/id registers and the interrupt wires,
and that's about it.
A board instantiates the device by setting the base SPI number and
number SPIs for the frame. The base-spi parameter is indexed in the SPI
number space only, so base-spi == 0, means IRQ number 32. When a device
(the PCI host controller) writes to the trigger register, the payload is
the GIC IRQ number, so we have to subtract 32 from that and then index
into our frame of SPIs.
When instantiating a GICv2m device, tell PCI that we have instantiated
something that can deal with MSIs. We rely on the board actually wiring
up the GICv2m to the PCI host controller.

monitor: Use trad. command interface for HMP pcie_aer_inject_error
All QMP commands use the "new" handler interface (mhandler.cmd_new).
Most HMP commands still use the traditional interface (mhandler.cmd),
but a few use the "new" one. Complicates handle_user_command() for no
gain, so I'm converting these to the traditional interface.
pcie_aer_inject_error's implementation is split into the
hmp_pcie_aer_inject_error() and pcie_aer_inject_error_print(). The
former is a peculiar crossbreed between HMP and QMP handler. On
success, it works like a QMP handler: store QDict through ret_data
parameter, return 0. Printing the QDict is left to
pcie_aer_inject_error_print(). On failure, it works more like an HMP
handler: print error to monitor, return negative number.
To convert to the traditional interface, turn
pcie_aer_inject_error_print() into a command handler wrapping around

monitor: Use traditional command interface for HMP device_add
All QMP commands use the "new" handler interface (mhandler.cmd_new).
Most HMP commands still use the traditional interface (mhandler.cmd),
but a few use the "new" one. Complicates handle_user_command() for no
gain, so I'm converting these to the traditional interface.
For device_add, that's easy: just wrap the obvious hmp_device_add()
around do_device_add().
monitor_user_noop() is now unused, drop it.

monitor: Drop broken, unused asynchronous command interface
The asynchronous monitor command interface goes back to commit 940cc30
(Jan 2010). Added a third case to command execution. The hope back
then according to the commit message was that all commands get
converted to the asynchronous interface, killing off the other two
cases. Didn't happen.
The initial asynchronous commands balloon and info balloon were
converted back to synchronous long ago (commit 96637bc and d72f32),
with commit messages calling the asynchronous interface "not fully
working" and "deprecated". The only other user went away in commit
3b5704b.
New code generally uses synchronous commands and asynchronous events.
What exactly is still "not fully working" with asynchronous commands?
Well, here's a bug that defeats actual asynchronous use pretty
reliably: the reply's ID is wrong (and has always been wrong) unless
you use the command synchronously! To reproduce, we need an
asynchronous command, so we have to go back before commit 3b5704b.
Run QEMU with spice:
$ qemu-system-x86_64 -nodefaults -S -spice port=5900,disable-ticketing -qmp stdio
{"QMP": {"version": {"qemu": {"micro": 94, "minor": 2, "major": 2}, "package": ""}, "capabilities": []}}
Connect a spice client in another terminal:
$ remote-viewer spice://localhost:5900
Set up a migration destination dummy in a third terminal:
$ socat TCP-LISTEN:12345 STDIO
Now paste the following into the QMP monitor:
{ "execute": "qmp_capabilities", "id": "i0" }
{ "execute": "client_migrate_info", "id": "i1", "arguments": { "protocol": "spice", "hostname": "localhost", "port": 12345 } }
{ "execute": "query-kvm", "id": "i2" }
Produces two replies immediately, one to qmp_capabilities, and one to
query-kvm:
{"return": {}, "id": "i0"}
{"return": {"enabled": false, "present": true}, "id": "i2"}
Both are correct. Two lines of debug output from libspice-server not
shown.
Now EOF socat's standard input to make it close the connection. This
makes the asynchronous client_migrate_info complete. It replies:
{"return": {}}
Bug: "id": "i1" is missing. Two lines of debug output from
libspice-server not shown. Cherry on top: storage for the missing ID
is leaked.
Get rid of this stuff before somebody hurts himself with it.

On migration a full 64bit guest_features field is sent if one of the

32 feature bits twice, but the code is simpler because we don't have

Extend TPM TIS interface to support TPM 2
Following the recent upgrade to version 1.3, extend the TPM TIS
interface with capabilities introduced for support of a TPM 2.
TPM TIS for TPM 2 introduced the following extensions beyond the
TPM TIS 1.3 (used for TPM 1.2):
- A new 32bit interface Id register was introduced.
- New flags for the status (STS) register were defined.
- New flags for the capability flags were defined.
Support the above if a TPM TIS 1.3 for TPM 2 is used with a TPM 2
on the backend side. Support the old TPM TIS 1.3 configuration if a
TPM 1.2 is being used. A subsequent patch will then determine which
TPM version is being used in the backend.

i386/pc_q35: don't insist on board FDC if there's no default floppy
The "no_floppy = 1" machine class setting causes "default_floppy" in
main() to become zero. Consequently, default_drive() will not call
drive_add() and drive_new() for IF_FLOPPY, index=0, meaning that no
default floppy drive will be created for the virtual machine. In that
case, board code should also not insist on the creation of the
board-default FDC.
The board-default FDC will still be created if the user requests a floppy
drive with "-drive if=floppy".
Additionally, separate FDCs can be specified manually with "-device
isa-fdc". They allow the
-device isa-fdc,driveA=...
syntax that is more flexible than the one required by the board-default
FDC:
-global isa-fdc.driveA=...
This patch doesn't change the behavior observably, as all Q35 machine
types have "no_floppy = 0".

i386/pc: '-drive if=floppy' should imply a board-default FDC
Even if board code decides not to request the creation of the FDC (keyed
off board-level factors, to be determined later), we should create the FDC
nevertheless if the user passes '-drive if=floppy' on the command line.
Otherwise '-drive if=floppy' would break without explicit '-device
isa-fdc' on such boards.

i386/pc: pc_basic_device_init(): delegate FDC creation request
This patch introduces no observable change, but it allows the callers of
pc_basic_device_init(), ie. pc_init1() and pc_q35_init(), to request (or
not request) the creation of the FDC explicitly.
At the moment both callers pass constant create_fdctrl=true (hence no
observable change).
Assuming a board passes create_fdctrl=false, "floppy" will be NULL on
output, and (beyond the FDC not being created) that NULL will be passed on
to pc_cmos_init(). Luckily, pc_cmos_init() already handles that case.

pc: acpi: fix pvpanic for buggy guests
In the old times, we always had pvpanic in ACPI and a _STA method told
the guest not to use it. Automatic generation dropped the _STA method
as the specification says that missing _STA means enabled and working.
Some guests (Linux) had buggy drivers and this change made them unable
to utilize pvpanic.
A Linux patch is posted as well, but I think it's worth to make pvpanic
useable on old guests at the price of three lines and few bytes of SSDT.
The old _STA method was
Method (_STA, 0, NotSerialized) {
Store (PEST, Local0)
If (LEqual (Local0, Zero)) {
Return (Zero) }
Else {
Return (0x0F) }}
Igor pointed out that we don't need to use a method to return a constant
and that 0xB (don't show in UI) is the common definition now.
Also, the device used to be PEVT. (PEVT as in "panic event"?)

pc: Define MACHINE_OPTIONS macros consistently for all machines
Define a MACHINE_OPTIONS macro for each PC machine, and move every field
inside the QEMUMachine structs to the macros, except for name, init, and
compat_props.
This also ensures that all MACHINE_OPTIONS inherit the fields from the
next version, so their definitions carry only the changes that exist
between one version and the next one.
Comments about specific cases:
pc-*-2.1:
Existing PC_*_2_1_MACHINE_OPTIONS macros were defined as:
PC_*_MACHINE_OPTIONS,
.default_machine_opts = "firmware=bios-256k.bin"
PC_*_2_2_MACHINE_OPTIONS is:
PC_*_2_3_MACHINE_OPTIONS
which is expanded to:
PC_*_MACHINE_OPTIONS,
.default_machine_opts = "firmware=bios-256k.bin",
.default_display = "std"
The only difference between 2_1 and 2_2 is .default_display, that's why
we didn't reuse PC_*_2_2_MACHINE_OPTIONS. The good news is that having
multiple initializers for a field is allowed by C99, and the last
initializer overrides the previous ones.
So we can reuse the 2_2 macro in 2_1 and define PC_*_2_1_MACHINE_OPTIONS
as:
PC_*_2_2_MACHINE_OPTIONS,
.default_display = NULL
pc-*-1.7:
PC_*_1_7_MACHINE_OPTIONS was defined as:
PC_*_MACHINE_OPTIONS
PC_*_2_0_MACHINE_OPTIONS is defined as:
PC_*_2_1_MACHINE_OPTIONS
which is expanded to:
PC_*_2_2_MACHINE_OPTIONS,
.default_display = NULL
which is expanded to:
PC_*_2_3_MACHINE_OPTIONS,
.default_display = NULL
which is expanded to:
PC_*_MACHINE_OPTIONS,
.default_machine_opts = "firmware=bios-256k.bin",
.default_display = "std",
.default_display = NULL /* overrides the previous line */
So, the only difference between PC_*_1_7_MACHINE_OPTIONS and
PC_*_2_0_MACHINE_OPTIONS is .default_machine_opts (as .default_display
is not explicitly set by PC_*_MACHINE_OPTIONS so it is NULL).
So we can keep the macro reuse pattern and define
PC_*_2_0_MACHINE_OPTIONS as:
PC_*_2_0_MACHINE_OPTIONS,
.default_machine_opts = NULL
pc-*-2.4 (alias and is_default fields):
Set alias and is_default fields inside the 2.4 MACHINE_OPTIONS macro,
and clear it in the 2.3 macro (that reuses the 2.4 macro).
hw_machine:
As all the machines older than v1.0 set hw_version explicitly, we can
safely move the field to the MACHINE_OPTIONS macros without affecting
the other versions that reuse them.
init function:
Some machines had the init function set inside the MACHINE_OPTIONS
macro. Move it to the QEMUMachine declaration, to keep it consistent
with the other machines.

So, move the properties to PC_COMPAT_0_14. This makes pc-0.13 and older
inherit them, but that shouldn't be an issue as QEMU 0.13 didn't support
qxl.

commit 9abe3bdc45ced367fe034c0fdd7c686212389767

qapi: add dirty bitmap status
Bitmaps can be in a handful of different states with potentially
more to come as we tool around with migration and persistence patches.
Management applications may need to know why certain bitmaps are
unavailable for various commands, e.g. busy in another operation,
busy being migrated, etc.
Right now, all we offer is BlockDirtyInfo's boolean member 'frozen'.
Instead of adding more booleans, replace it by an enumeration member
'status' with values 'active' and 'frozen'. Then add new value
'disabled'.
Incompatible change. Fine because the changed part hasn't been
released so far.

target-arm: Avoid buffer overrun on UNPREDICTABLE ldrd/strd
A LDRD or STRD where rd is not an even number is UNPREDICTABLE.
We were letting this fall through, which is OK unless rd is 15,
in which case we would attempt to do a load_reg or store_reg
to a nonexistent r16 for the second half of the double-word.
Catch the odd-numbered-rd cases and UNDEF them instead.
To do this we rearrange the structure of the code a little
so we can put the UNDEF catches at the top before we've
allocated TCG temporaries.

The required ACPI v5.1 tables for ARM are:
- RSDP: Initial table that points to XSDT
- RSDT: Points to FADT GTDT MADT tables
- FADT: Generic information about the machine
- GTDT: Generic timer description table
- MADT: Multiple APIC description table
- DSDT: Holds all information about system devices/peripherals, pointed by FADT

virtio-input: emulated devices [device]
This patch adds the virtio-input-hid base class and
virtio-{keyboard,mouse,tablet} subclasses building on the base class.
They are hooked up to the qemu input core and deliver input events
to the guest like all other hid devices (ps/2 kbd, usb tablet, ...).
Using them is as simple as adding "-device virtio-tablet-device" to
your command line, for use all transports except pci. virtio-pci
support comes as separate patch, once virtio-pci got virtio 1.0
support.

kbd: add brazil kbd keys to qemu
The brazilian computer keyboard layout has two extra keys (compared to
the usual 105-key intl ps/2 keyboard). This patch makes these two keys
known to qemu.
For historic reasons qemu has two ways to specify a key: A QKeyCode
(name-based) or a number (ps/2 scancode based). Therefore we have to
update multiple places to make new keys known to qemu:
(1) The QKeyCode definition in qapi-schema.json
(2) The QKeyCode <-> number mapping table in ui/input-keymap.c
This patch does just that. With this patch applied you can send those
two keys to the guest using the send-key monitor command.

net/net: Record usage status of mac address
Currently QEMU dynamically generates mac address for the NIC which
doesn't specify the mac address. But when we hotplug a NIC without
specifying mac address, the mac address will increase for the same NIC
along with hotplug and hot-unplug, and at last it will overflow. And if
we codeplug one NIC with mac address e.g. "52:54:00:12:34:56", then
hotplug one NIC without specifying mac address and the mac address of
the hotplugged NIC is duplicate of "52:54:00:12:34:56".
This patch add a mac_table to record the usage status and free the mac
address when the NIC is unrealized.

tap: Improve -netdev/netdev_add/-net/... tap error reporting
When -netdev tap fails, it first reports a specific error, then a
generic one, like this:
$ qemu-system-x86_64 -netdev tap,id=foo
qemu-system-x86_64: -netdev tap,id=foo: could not configure /dev/net/tun: Operation not permitted
qemu-system-x86_64: -netdev tap,id=foo: Device 'tap' could not be initialized
With the command line, the messages go to stderr. In HMP, they go to
the monitor. In QMP, the second one becomes the error reply, and the
first one goes to stderr.
Convert net_init_tap() to Error. This suppresses the unwanted second
message, and makes the specific error the QMP error reply.
[Dropped duplicate "and" from error message as suggested by Eric Blake:
"ifname=, script=, downscript=, and vnet_hdr=, "
"queues=, and vhostfds= are invalid with helper="

tap: Improve -netdev/netdev_add/-net/... bridge error reporting
When -netdev bridge fails, it first reports a specific error, then a
generic one, like this:
$ qemu-system-x86_64 -netdev bridge,id=foo
failed to launch bridge helper
qemu-system-x86_64: -netdev bridge,id=foo: Device 'bridge' could not be initialized
The first message goes to stderr. Wrong for HMP, because errors need
to go to the monitor there.
The second message goes to stderr for -netdev, to the monitor for HMP
netdev_add, and becomes the error reply for QMP netdev_add.
Convert net_bridge_run_helper() to Error, and propagate its errors
through net_init_bridge(). This ensures the error gets reported where
the user is, and suppresses the unwanted second message.
While there, improve the error messages a bit.
The above example becomes:
$ qemu-system-x86_64 -netdev bridge,id=foo
qemu-system-x86_64: -netdev bridge,id=foo: bridge helper failed
net_init_tap() also uses net_bridge_run_helper(). Propagate its
errors there as well. Improves reporting these errors with -netdev
tap & friends.

net: Permit incremental conversion of init functions to Error
Error reporting for netdev_add is broken: the net_client_init_fun[]
report the actual errors with (at best) error_report(), and their
caller net_client_init1() makes up a generic error on top.
For command line and HMP, this produces an mildly ugly error cascade.
In QMP, the actual errors go to stderr, and the generic error becomes
the command's error reply.
To fix this, we need to convert the net_client_init_fun[] to Error.
To permit fixing them one by one, add an Error ** parameter to the
net_client_init_fun[]. If the call fails without returning an Error,
make up the same generic Error as before. But if it returns one, use
that instead. Since none of them does so far, no functional change.

net: Change help text to list -netdev instead of -net by default
Looking at the output of "qemu-system-xxx -help", you easily get
the impression that "-net" is the preferred way instead of "-netdev"
to specify host network interface, since the "-net" option is
omnipresent but the "-netdev" option is only listed as a one-liner
at the end. This is ugly since "-net" is considered as legacy and
even might be removed one day. Thus, this patch switches the output
to explain the host network interfaces with the "-netdev" option
instead, moving the old "-net" option into some few lines at
the end.

ahci: do not remap clb/fis unconditionally
This continues the IOMMU fix from 2.3, where we should not attempt
to remap the CLB or FIS RX buffers if the AHCI device is currently
running.
The same applies to migration: keep our mitts off these registers
unless the device is supposed to be on.
Does not impact backwards compatibility for the AHCI device.

qtest: pre-buffer hex nibs
Instead of converting each byte one-at-a-time and then sending each byte
over the wire, use sprintf() to pre-compute all of the hex nibs into a
single buffer, then send the entire buffer all at once.
This gives a moderate speed boost to memread() and memwrite() functions.

qtest: Add base64 encoded read/write
For larger pieces of data that won't need to be debugged and
viewing the hex nibbles is unlikely to be useful, we can encode
data using base64 instead of encoding each byte as %02x, which
leads to some space savings and faster reads/writes.
For now, the default is left as hex nibbles in memwrite() and memread().
For the purposes of making qtest io easier to read and debug, some
callers may want to specify using the old encoding format for small
patches of data where the savings from base64 wouldn't be that profound.
memwrite/memread use a data encoding that takes 2x the size of the original
buffer, but base64 uses "only" (4/3)x, so for larger buffers we can save a
decent amount of time and space.

qtest: allow arbitrarily long sends
qtest currently has a static buffer of size 1024 that if we
overflow, ignores the additional data silently which leads
to hangs or stream failures.
Use glib's string facilities to allow arbitrarily long data,
but split this off into a new function, qtest_sendf.
Static data can still be sent using qtest_send, which avoids
the malloc/copy overhead.

* The migration is performed on QOSState objects.
* The migration is performed in such a way that it does not assume
consistency between the allocators attached to each. That is to say,
you can use each QOSState object completely independently and then at
an arbitrary point decide to migrate, and the destination object will
now be consistent with the memory within the source guest. The source
object that was migrated from will have a completely blank allocator.

- verify_state is added
- ahci_migrate is added as a frontend to migrate
- test_migrate_sanity test case is added.

qemu-io: prompt for encryption keys when required
The qemu-io tool does not check if the image is encrypted so
historically would silently corrupt the sectors by writing
plain text data into them instead of cipher text. The earlier
commit turns this mistake into a fatal abort, so check for
encryption and prompt for key when required.
This enables us to add unit tests to ensure we don't break
the ability of qemu-img to convert existing encrypted qcow2
files into a non-encrypted format.

qcow2/qcow: protect against uninitialized encryption key
When a qcow[2] file is opened, if the header reports an
encryption method, this is used to set the 'crypt_method_header'
field on the BDRVQcow[2]State struct, and the 'encrypted' flag
in the BDRVState struct.
When doing I/O operations, the 'crypt_method' field on the
BDRVQcow[2]State struct is checked to determine if encryption
needs to be applied.
The crypt_method_header value is copied into crypt_method when
the bdrv_set_key() method is called.
The QEMU code which opens a block device is expected to always
do a check
if (bdrv_is_encrypted(bs)) {
bdrv_set_key(bs, ....key...);
}
If code forgets to do this, then 'crypt_method' is never set
and so when I/O is performed, QEMU writes plain text data
into a sector which is expected to contain cipher text, or
when reading, will return cipher text instead of plain
text.
Change the qcow[2] code to consult bs->encrypted when deciding
whether encryption is required, and assert(s->crypt_method)
to protect against cases where the caller forgets to set the
encryption key.
Also put an assert in the set_key methods to protect against
the case where the caller sets an encryption key on a block
device that does not have encryption

qemu-iotests: Make debugging python tests easier
Adding "-d" option. The output goes to "tee" so it appears in your
console. Also, raise the verbosity of unnitest runner.
When testing a topic branch, it's possible that a bug introduced by a
code change makes the python test case hang, with debug output, it is
much easier to locate the problem.
This can also be helpful if you want to watch the progress of a python
test, it offers you a way to sense the speed of each test case method
you're writing.
Note: because there is no easy way to get *both* the verbose output and
the output expected by ./check comparison, the case would always fail
with an "output mismatch". The sole purpose of using this option is
giving developers a quick way to debug when things go wrong.

qcow2: use a hash to look for entries in the L2 cache
The current cache algorithm traverses the array starting always from
the beginning, so the average number of comparisons needed to perform
a lookup is proportional to the size of the array.
By using a hash of the offset as the starting point, lookups are
faster and independent from the array size.
The hash is computed using the cluster number of the table, multiplied
by 4 to make it perform better when there are collisions.
In my tests, using a cache with 2048 entries, this reduces the average
number of comparisons per lookup from 430 to 2.5.

qcow2: use an LRU algorithm to replace entries from the L2 cache
The current algorithm to evict entries from the cache gives always
preference to those in the lowest positions. As the size of the cache
increases, the chances of the later elements of being removed decrease
exponentially.
In a scenario with random I/O and lots of cache misses, entries in
positions 8 and higher are rarely (if ever) evicted. This can be seen
even with the default cache size, but with larger caches the problem
becomes more obvious.
Using an LRU algorithm makes the chances of being removed from the
cache independent from the position.

qcow2: use one single memory block for the L2/refcount cache tables
The qcow2 L2/refcount cache contains one separate table for each cache
entry. Doing one allocation per table adds unnecessary overhead and it
also requires us to store the address of each table separately.
Since the size of the cache is constant during its lifetime, it's
better to have an array that contains all the tables using one single
allocation.
In my tests measuring freshly created caches with sizes 128MB (L2) and
32MB (refcount) this uses around 10MB of RAM less.

vmdk: Fix overflow if l1_size is 0x20000000
Richard Jones caught this bug with afl fuzzer.
In fact, that's the only possible value to overflow (extent->l1_size =
0x20000000) l1_size:
l1_size = extent->l1_size * sizeof(long) => 0x80000000;
g_try_malloc returns NULL because l1_size is interpreted as negative
during type casting from 'int' to 'gsize', which yields a enormous
value. Hence, by coincidence, we get a "not too bad" behavior:
qemu-img: Could not open '/tmp/afl6.img': Could not open
'/tmp/afl6.img': Cannot allocate memory
Values larger than 0x20000000 will be refused by the validation in
vmdk_add_extent.
Values smaller than 0x20000000 will not overflow l1_size.

qcow2: Flush pending discards before allocating cluster
Before a freed cluster can be reused, pending discards for this cluster
must be processed.
The original assumption was that this was not a problem because discards
are only cached during discard/write zeroes operations, which are
synchronous so that no concurrent write requests can cause cluster
allocations.
However, the discard/write zeroes operation itself can allocate a new L2
table (and it has to in order to put zero flags there), so make sure we
can cope with the situation.
This fixes https://bugs.launchpad.net/bugs/1349972.

block: get_block_status: use "else" when testing the opposite condition
A bit of Boolean algebra (and common sense) tells us that the
second "if" here is looking for blocks that are not allocated.
This is the opposite of the "if" that sets BDRV_BLOCK_ALLOCATED,
and thus it can use an "else".

block: Fix NULL deference for unaligned write if qiov is NULL
For zero write, callers pass in NULL qiov (qemu-io "write -z" or
scsi-disk "write same").
Commit fc3959e466 fixed bdrv_co_write_zeroes which is the common case
for this bug, but it still exists in bdrv_aio_write_zeroes. A simpler
fix would be in bdrv_co_do_pwritev which is the NULL dereference point
and covers both cases.
So don't access it in bdrv_co_do_pwritev in this case, use three aligned
writes.
[Initialize ret to 0 in bdrv_co_do_zero_pwritev() to avoid uninitialized
variable warning with gcc 4.9.2.

block: align bounce buffers to page
The following sequence
int fd = open(argv[1], O_RDWR | O_CREAT | O_DIRECT, 0644);
for (i = 0; i < 100000; i++)
write(fd, buf, 4096);
performs 5% better if buf is aligned to 4096 bytes.
The difference is quite reliable.
On the other hand we do not want at the moment to enforce bounce
buffering if guest request is aligned to 512 bytes.
The patch changes default bounce buffer optimal alignment to
MAX(page size, 4k). 4k is chosen as maximal known sector size on real
HDD.
The justification of the performance improve is quite interesting.
From the kernel point of view each request to the disk was split
by two. This could be seen by blktrace like this:
9,0 11 1 0.000000000 11151 Q WS 312737792 + 1023 [qemu-img]
9,0 11 2 0.000007938 11151 Q WS 312738815 + 8 [qemu-img]
9,0 11 3 0.000030735 11151 Q WS 312738823 + 1016 [qemu-img]
9,0 11 4 0.000032482 11151 Q WS 312739839 + 8 [qemu-img]
9,0 11 5 0.000041379 11151 Q WS 312739847 + 1016 [qemu-img]
9,0 11 6 0.000042818 11151 Q WS 312740863 + 8 [qemu-img]
9,0 11 7 0.000051236 11151 Q WS 312740871 + 1017 [qemu-img]
9,0 5 1 0.169071519 11151 Q WS 312741888 + 1023 [qemu-img]
After the patch the pattern becomes normal:
9,0 6 1 0.000000000 12422 Q WS 314834944 + 1024 [qemu-img]
9,0 6 2 0.000038527 12422 Q WS 314835968 + 1024 [qemu-img]
9,0 6 3 0.000072849 12422 Q WS 314836992 + 1024 [qemu-img]
9,0 6 4 0.000106276 12422 Q WS 314838016 + 1024 [qemu-img]
and the amount of requests sent to disk (could be calculated counting
number of lines in the output of blktrace) is reduced about 2 times.
Both qemu-img and qemu-io are affected while qemu-kvm is not. The guest
does his job well and real requests comes properly aligned (to page).

block: minimal bounce buffer alignment
The patch introduces new concept: minimal memory alignment for bounce
buffers. Original so called "optimal" value is actually minimal required
value for aligment. It should be used for validation that the IOVec
is properly aligned and bounce buffer is not required.
Though, from the performance point of view, it would be better if
bounce buffer or IOVec allocated by QEMU will be aligned stricter.
The patch does not change any alignment value yet.

block: return EPERM on writes or discards to read-only devices
This is the behavior in the operating system, for example Linux's
blkdev_write_iter has the following:
if (bdev_read_only(I_BDEV(bd_inode)))
return -EPERM;
This does not apply to opening a device for read/write, when the
device only supports read-only operation. In this case any of
EACCES, EPERM or EROFS is acceptable depending on why writing is
not possible.

configure: Add workaround for ccache and clang
Test if ccache is interfering with semantic analysis of macros,
disable its habit of trying to compile already pre-processed
versions of code if so. ccache attempts to save time by compiling
pre-processed versions of code, but this disturbs clang's static
analysis enough to produce false positives.
ccache allows us to disable this feature, opting instead to
compile the original version instead of its preprocessed version.
This makes ccache much slower for cache misses, but at least it
becomes usable with QEMU/clang.
This workaround only activates for users using ccache AND clang,
and only if their configuration is observed to be producing warnings.
You may need to clear your ccache for builds started without -Werror,
as those may continue to produce warnings from the cache.

block/parallels: optimize linear image expansion
Plain image expansion spends a lot of time to update image file size.
This seriously affects the performance. The following simple test
qemu_img create -f parallels -o cluster_size=64k ./1.hds 64G
qemu_io -n -c "write -P 0x11 0 1024M" ./1.hds
could be improved if the format driver will pre-allocate some space
in the image file with a reasonable chunk.
This patch preallocates 128 Mb using bdrv_write_zeroes, which should
normally use fallocate() call inside. Fallback to older truncate()
could be used as a fallback using image open options thanks to the
previous patch.
The benefit is around 15%.

block/parallels: add prealloc-mode and prealloc-size open paramemets
This is preparational commit for tweaks in Parallels image expansion.
The idea is that enlarge via truncate by one data block is slow. It
would be much better to use fallocate via bdrv_write_zeroes and
expand by some significant amount at once.
Original idea with sequential file writing to the end of the file without
fallocate/truncate would be slower than this approach if the image is
expanded with several operations:
- each image expanding means file metadata update, i.e. filesystem
journal write. Truncate/write to newly truncated space update file
metadata twice thus truncate removal helps. With fallocate call
inside bdrv_write_zeroes file metadata is updated only once and
this should happen infrequently thus this approach is the best one
for the image expansion
- tail writes are ordered, i.e. the guest IO queue could not be sent
immediately to the host introducing additional IO delays
This patch just adds proper parameters into BDRVParallelsState and
performs options parsing in parallels_open.

block/parallels: delay writing to BAT till bdrv_co_flush_to_os
The idea is that we do not need to immediately sync BAT to the image as
from the guest point of view there is a possibility that IO is lost
even in the physical controller until flush command was finished.
bdrv_co_flush_to_os is exactly the right place for this purpose.
Technically the patch uses loaded BAT data as a cache and performs
actual on-disk metadata updates in parallels_co_flush_to_os callback.
This patch speed ups
qemu-img create -f parallels -o cluster_size=64k ./1.hds 64G
qemu-io -f parallels -c "write -P 0x11 0 1024k" 1.hds
writing from 50-60 Mb/sec to 80-90 Mb/sec on rotational media and
from 160 Mb/sec to 190 Mb/sec on SSD disk.

Author: Denis V. Lunev <den@openvz.org>

block/parallels: implement incorrect close detection
The software driver must set inuse field in Parallels header to
0x746F6E59 when the image is opened in read-write mode. The presence of
this magic in the header on open forces image consistency check.
There is an unfortunate trick here. We can not check for inuse in
parallels_check as this will happen too late. It is possible to do
that for simple check, but during the fix this would always report
an error as the image was opened in BDRV_O_RDWR mode. Thus we save
the flag in BDRVParallelsState for this.
On the other hand, nothing should be done to clear inuse in
parallels_check. Generic close will do the job right.

block/parallels: implement parallels_check method of block driver
The check is very simple at the moment. It calculates necessary stats
and fix only the following errors:
- space leak at the end of the image. This would happens due to
preallocation
- clusters outside the image are zeroed. Nothing else could be done here

serial: fix multi-pci card error cleanup.
Put the number of serial ports into a local variable in
multi_serial_pci_realize, then increment the port count
(pci->ports) as we initialize the serial port cores.
Now pci->ports always holds the number of successfully
initialized ports and we can use multi_serial_pci_exit
to properly cleanup the already initialized bits in case
of a init failure.

ui/cocoa: Avoid deprecated NSOKButton/NSCancelButton constants
In OSX 10.10, the NSOKButton and NSCancelButton constants are deprecated
and provoke compiler warnings. Avoid them by using the
NSFileHandlingPanelCancelButton and NSFileHandlingPanelOKButton constants
instead. These are the documented correct constants for the 10.6-and-up
beginSheetModalForWindow API we use. We also use the same method for
the pre-10.6 compatibility code path, but conveniently the constant
values are the same and the constant names have been present since 10.0.
Preferring the constant names that match the non-legacy API makes more
sense anyway.

ui/cocoa: Declare that QemuCocoaAppController implements NSApplicationDelegate
Our class QemuCocoaAppController implements the NSApplicationDelegate
interface, and we pass an object of this class to [NSApp setDelegate].
However, we weren't declaring in the class definition that we implemented
this interface; in OSX 10.10 this provokes the following (slighly
misleading) warning:
ui/cocoa.m:1031:24: warning: sending 'QemuCocoaAppController *' to parameter of
incompatible type 'id<NSFileManagerDelegate>'
[NSApp setDelegate:appController];
^~~~~~~~~~~~~
/System/Library/Frameworks/Foundation.framework/Headers/NSFileManager.h:109:47:
note: passing argument to parameter 'delegate' here
@property (assign) id <NSFileManagerDelegate> delegate NS_AVAILABLE(10_5,
2_0);
^
Annoyingly, this interface wasn't formally defined until OSX 10.6, so we
have to surround the relevant part of the @interface line with an ifdef.

ui/cocoa: Drop tests for CGImageCreateWithImageInRect support
The code that tries to test at both compiletime and runtime
for whether CGImageCreateWithImageInRect is supported provokes
a compile warning on OSX 10.3:
ui/cocoa.m:378:13: warning: comparison of function 'CGImageCreateWithImageInRect'
equal to a null pointer is always false[-Wtautological-pointer-compare]
if (CGImageCreateWithImageInRect == NULL) { // test if "CGImageCreateWithImageInRect" is
supported on host at runtime
^~~~~~~~~~~~~~~~~~~~~~~~~~~~ ~~~~
The simplest way to deal with this is just to drop this code,
since we don't in practice support OSX 10.4 anyway. (10.5 was
released in 2007 and is the last PPC version, so is the earliest
we really need to continue to support at all.)

- Makes full screen mode available on Mac OS 10.7 and higher.
- Allows user to decide if video should be stretched to fill the
screen, using a menu item called "Zoom To Fit".
- Hides the normalWindow so it won't show up in full screen mode.

qapi: qapi-commands.py option --type is unused, drop it
Anything but --type sync (which is the default) suppresses output
entirely, which makes no sense.
Dates back to the initial commit c17d990. Commit message says
"Currently only generators for synchronous qapi/qmp functions are
supported", so maybe output other than "synchronous qapi/qmp" was
planned at the time, to be selected with --type.
Should other kinds of output ever materialize, we can put the option
back.

In making those tweaks, it was easier to drop type_visitor() and
inline its actions instead.

qapi: Make c_type() consistently convert qapi names
Continuing the string of cleanups for supporting downstream names
containing '.', this patch focuses on ensuring c_type() can
handle a downstream name. This patch alone does not fix the
places where generator output should be calling this function
but was open-coding things instead, but it gets us a step closer.
In particular, the changes to c_list_type() and type_name() mean
that type_name(FOO) now handles the case when FOO contains '.',
'-', or is a ticklish identifier other than a builtin (builtins
are exempted because ['int'] must remain mapped to 'intList' and
not 'q_intList'). Meanwhile, ['unix'] now maps to 'q_unixList'
rather than 'unixList', to match the fact that 'unix' is ticklish;
however, our naming conventions state that complex types should
start with a capital, so no type name following conventions will
ever have the 'q_' prepended.
Likewise, changes to c_type() mean that c_type(FOO) properly
handles an enum or complex type FOO with '.' or '-' in the
name, or is a ticklish identifier (again, a ticklish identifier
as a type name violates conventions).

qapi: Tidy c_type() logic
c_type() is designed to be called on both string names and on
array designations, so 'name' is a bit misleading because it
operates on more than strings. Also, no caller ever passes
an empty string. Finally, + notation is a bit nicer to read
than '%s' % value for string concatenation.

Now that the two functions are identical, we only need one of them,

the function serves as the translation from a QAPI name into a

qapi: Fix C identifiers generated for names containing '.'
c_fun() maps '.' to '_', c_var() doesn't. Nothing prevents '.' in
QAPI names that get passed to c_var().
Which QAPI names get passed to c_fun(), to c_var(), or to both is not
obvious. Names of command parameters and struct type members get
passed to c_var().
c_var() strips a leading '*', but this cannot happen. c_fun()
doesn't.
Fix c_var() to work exactly like c_fun().
Perhaps they should be replaced by a single mapping function.

hw/intc/arm_gic: Make ICCICR/GICC_CTLR banked
ICCICR/GICC_CTLR is banked in GICv1 implementations with Security
Extensions or in GICv2 in independent from Security Extensions.
This makes it possible to enable forwarding of interrupts from
the CPU interfaces to the connected processors for Group0 and Group1.
We also allow to set additional bits like AckCtl and FIQEn by changing
the type from bool to uint32. Since the field does not only store the
enable bit anymore and since we are touching the vmstate, we use the
opportunity to rename the field to cpu_ctlr.

hw/intc/arm_gic: Add Interrupt Group Registers
The Interrupt Group Registers allow the guest to configure interrupts
into one of two groups, where Group0 are higher priority and may
be routed to IRQ or FIQ, and Group1 are lower priority and always
routed to IRQ. (In a GIC with the security extensions Group0 is
Secure interrupts and Group 1 is NonSecure.)
The GICv2 always supports interrupt grouping; the GICv1 does only
if it implements the security extensions.
This patch implements the ability to read and write the registers;
the actual functionality the bits control will be added in a
subsequent patch.

armv7m_nvic: systick: Reload the RELOAD value and count down only if ENABLE bit is set
Consider the following pseudo code to configure SYSTICK (The
recommended programming sequence from "the definitive guide to the
arm cortex-m3"):
SYSTICK Reload Value Register = 0xffff
SYSTICK Current Value Register = 0
SYSTICK Control and Status Register = 0x7
The pseudo code "SYSTICK Current Value Register = 0" leads to invoking
systick_reload(). As a consequence, the systick.tick member is updated
and the systick timer starts to count down when the ENABLE bit of
SYSTICK Control and Status Register is cleared.
The worst case is that: during the system initialization, the reset
value of the SYSTICK Control and Status Register is 0x00000000.
When the code "SYSTICK Current Value Register = 0" is executed, the
systick.tick member is accumulated with "(s->systick.reload + 1) *
systick_scale(s)". The systick_scale() gets the external_ref_clock
scale because the CLKSOURCE bit of the SYSTICK Control and Status
Register is cleared. This is the incorrect behavior because of the
code "SYSTICK Control and Status Register = 0x7". Actually, we want
the processor clock instead of the external reference clock.
This incorrect behavior defers the generation of the first interrupt.
The patch fixes the above-mentioned issue by setting the systick.tick
member and modifying the systick timer only if the ENABLE bit of
the SYSTICK Control and Status Register is set.
In addition, the Cortex-M3 Devices Generic User Guide mentioned that
"When ENABLE is set to 1, the counter loads the RELOAD value from the
SYST RVR register and then counts down". This patch adheres to the
statement of the user guide.

rocker: add new rocker switch device
Rocker is a simulated ethernet switch device. The device supports up to 62
front-panel ports and supports L2 switching and L3 routing functions, as well
as L2/L3/L4 ACLs. The device presents a single PCI device for each switch,
with a memory-mapped register space for device driver access.
Rocker device is invoked with -device, for example a 4-port switch:
-device rocker,name=sw1,len-ports=4,ports[0]=dev0,ports[1]=dev1, \
ports[2]=dev2,ports[3]=dev3
Each port is a netdev and can be paired with using -netdev id=<port name>.

rocker: add support for flow modification
We had support for flow add/del. This adds support for flow mod. I needed
this for L3 support where an existing route is modified using NLM_F_REPLACE.
For example:
ip route add 12.0.0.0/30 nexthop via 11.0.0.1 dev swp1
ip route change 12.0.0.0/30 nexthop via 11.0.0.9 dev swp2
The first cmd adds the route. The second cmd changes the existing route by
changing its nexthop info.
In the device, a mod operation results in the matching flow enty being modified
with the new settings. This is atomic to the device.

scripts: qmp-shell: Add verbose flag
Add a verbose flag that shows the QMP command that was
constructed, to allow for later copy/pasting, reference,
debugging, etc.
The QMP is converted from a Python literal to JSON first,
to ensure that it is viable input to the actual QMP parser.
As a side-effect, this JSON output will helpfully show all
the necessary conversions that were performed on the input,
illustrating that "True" was transformed back into "true",
literal values are now escaped with "" instead of '', and so on.

scripts: qmp-shell: add transaction subshell
Add a special processing mode to craft transactions.
By entering "transaction(" the shell will enter a special
mode where each subsequent command will be saved as a transaction
instead of executed as an individual command.
The transaction can be submitted by entering ")" on a line by itself.
Examples:
Separate lines:
(QEMU) transaction(
TRANS> block-dirty-bitmap-add node=drive0 name=bitmap1
TRANS> block-dirty-bitmap-clear node=drive0 name=bitmap0
TRANS> )
With a transaction action included on the first line:
(QEMU) transaction( block-dirty-bitmap-add node=drive0 name=bitmap2
TRANS> block-dirty-bitmap-add node=drive0 name=bitmap3
TRANS> )
As a one-liner, with just one transaction action:
(QEMU) transaction( block-dirty-bitmap-add node=drive0 name=bitmap0 )
As a side-effect of this patch, blank lines are now parsed as no-ops,
regardless of which shell mode you are in.

Author: John Snow <jsnow@redhat.com>
Date: Wed Apr 29 15:14:02 2015 -0400
scripts: qmp-shell: Expand support for QMP expressions
This includes support for [] expressions, single-quotes in
QMP expressions (which is not strictly a part of JSON), and
the ability to use "True", "False" and "None" literals instead
of JSON's equivalent true, false, and null literals.
qmp-shell currently allows you to describe values as
JSON expressions:
key={"key":{"key2":"val"}}
But it does not currently support arrays, which are needed
for serializing and deserializing transactions:
key=[{"type":"drive-backup","data":{...}}]
qmp-shell also only currently accepts doubly quoted strings
as-per JSON spec, but QMP allows single quotes.
Lastly, python allows you to utilize "True" or "False" as
boolean literals, but JSON expects "true" or "false". Expand
qmp-shell to allow the user to type either, converting to the
correct type.
As a consequence of the above, the key=val parsing is also improved
to give better error messages if a key=val token is not provided.
CAVEAT: The parser is still extremely rudimentary and does not
expect to find spaces in {} nor [] expressions. This patch does
not improve this functionality.

MAINTAINERS: New maintainer for QMP and QAPI
Markus is taking over maintership of QMP and the QAPI from
me. Markus has always been a great reviewer and contributor
to those subsystems. In the last few months he's also doing
pull requests that are a lot more relevant than the ones I
was able to do. So, this is a natural move.
I'm still the maintainer of HMP and QObjects, but I'm
looking for someone to take over those too.

json-parser: Accept 'null' in QMP
We document that in QMP, the client may send any json-value
for the optional "id" key, and then return that same value
on reply (both success and failures, insofar as the failure
happened after parsing the id). [Note that the output may
not be identical to the input, as whitespace may change and
since we may reorder keys within a json-object, but that this
still constitutes the same json-value]. However, we were not
handling the JSON literal null, which counts as a json-value
per RFC 7159.
Also, down the road, given the QAPI schema of {'*foo':'str'} or
{'*foo':'ComplexType'}, we could decide to allow the QMP client
to pass { "foo":null } instead of the current representation of
{ } where omitting the key is the only way to get at the default
NULL value. Such a change might be useful for argument
introspection (if a type in older qemu lacks 'foo' altogether,
then an explicit "foo":null probe will force an easily
distinguished error message for whether the optional "foo" key
is even understood in newer qemu). And if we add default values
to optional arguments, allowing an explicit null would be
required for getting a NULL value associated with an optional
string that has a non-null default. But all that can come at a
later day.
The 'check-unit' testsuite is enhanced to test that parsing
produces the same object as explicitly requesting a reference
to the special qnull object. In addition, I tested with:
$ ./x86_64-softmmu/qemu-system-x86_64 -qmp stdio -nodefaults
{"QMP": {"version": {"qemu": {"micro": 91, "minor": 2, "major": 2}, "package": ""}, "capabilities": []}}
{"execute":"qmp_capabilities","id":null}
{"return": {}, "id": null}
{"id":{"a":null,"b":[1,null]},"execute":"quit"}
{"return": {}, "id": {"a": null, "b": [1, null]}}
{"timestamp": {"seconds": 1427742379, "microseconds": 423128}, "event": "SHUTDOWN"}

qobject: Add a special null QObject
I'm going to fix the JSON parser to recognize null. The obvious
representation of JSON null as (QObject *)NULL doesn't work, because
the parser already uses it as an error value. Perhaps we should
change it to free NULL for null, but that's more than I can do right
now. Create a special null QObject instead.
The existing QDict, QList, and QString all represent something that
is a pointer in C and could therefore be associated with NULL. But
right now, all three of these sub-types are always non-null once
created, so the new null sentinel object is intentionally unrelated
to them.

qemu-nbd: only send a limited number of errno codes on the wire
Right now, NBD includes potentially platform-specific error values in
the wire protocol.
Luckily, most common error values are more or less universal: in
particular, of all errno values <= 34 (up to ERANGE), they are all the
same on supported platforms except for 11 (which is EAGAIN on Windows and
Linux, but EDEADLK on Darwin and the *BSDs). So, in order to guarantee
some portability, only keep a handful of possible error codes and squash
everything else to EINVAL.
This patch defines a limited set of errno values that are valid for the
NBD protocol, and specifies recommendations for what error to return
in specific corner cases. The set of errno values is roughly based on
the errors listed in the read(2) and write(2) man pages, with some
exceptions:
- ENOMEM is added for servers that implement copy-on-write or other
formats that require dynamic allocation.
- EDQUOT is not part of the universal set of errors; it can be changed
to ENOSPC on the wire format.
- EFBIG is part of the universal set of errors, but it is also changed
to ENOSPC because it is pretty similar to ENOSPC or EDQUOT.
Incoming values will in general match system errno values, but not
on the Hurd which has different errno values (they have a "subsystem
code" equal to 0x10 in bits 24-31). The Hurd is probably not something
to which QEMU has been ported, but still do the right thing and
reverse-map the NBD errno values to the system errno values.
The corresponding patch to the NBD protocol description can be found at
http://article.gmane.org/gmane.linux.drivers.nbd.general/3154.

rules.mak: Force CFLAGS for all objects in DSO
Because of the trick of process-archive-undefs, all .mo objects, even
with --enable-modules, are dependencies of executables.
This breaks CFLAGS propogation because the compiling of module object
will happen too early before building for DSO.
With GCC 5, the linking would fail because .o doesn't have -fPIC. Also,
BUILD_DSO will be missed. (module-common.o will have it, so the stamp
symbol was still liked in .so).
Fix the problem by forcing the CFLAGS on individual .o-cflags during
unnest-vars.

usb: fix usb-net segfault
The dev->config pointer isn't set until guest
system initializes usb devices (via
usb_desc_set_config). However qemu networking can
go through some motions prior to that, e.g.:
#0 is_rndis (s=0x555557261970) at hw/usb/dev-network.c:653
#1 0x000055555585f723 in usbnet_can_receive (nc=0x55555641e820) at hw/usb/dev-network.c:1315
#2 0x000055555587635e in qemu_can_send_packet (sender=0x5555572660a0) at net/net.c:470
#3 0x0000555555878e34 in net_hub_port_can_receive (nc=0x5555562d7800) at net/hub.c:101
#4 0x000055555587635e in qemu_can_send_packet (sender=0x5555562d7980) at net/net.c:470
#5 0x000055555587dbca in tap_can_send (opaque=0x5555562d7980) at net/tap.c:172
The command to reproduce most reliably was:
qemu-system-i386 -usb -device usb-net,vlan=0 -net tap,vlan=0
This wasn't strictly a problem with tap. Other
networking endpoints (vde, user) could trigger
this problem as well.

s390x/kvm: use ioctl KVM_S390_IRQ for vcpu interrupts
KVM_S390_INT uses only two parameter fields. This is not
enough to pass all required information for certain interrupts.
A new ioctl KVM_S390_IRQ is available which allows us to
inject all local interrupts as defined in the Principles of
Operation. It takes a struct kvm_s390_irq as a parameter
which can store interrupt payload data for all interrupts.
Let's use the new ioctl for injecting vcpu interrupts.

virtio-ccw: change realization sequence
virtio-ccw has an odd sequence of realizing devices: first the
device-specific relization (net, block, ...), then the generic
realization. It feels less odd to have the generic realization
callback trigger the device-specific realization instead (and this
also matches what virtio-pci does).
One thing to note: We need to defer initializing the cu model in the
sense id data until after the device-specific realization has been
performed, as we need to refer to the virtio device's device_id.

We used to avoid enabling event_idx for virtio-blk devices via
s390-virtio, but we now have a workaround in place for guests trying
to use the device before setting DRIVER_OK. Therefore, let's add
DEFINE_VIRTIO_COMMON_FEATURES to the base device so all devices get
those common features - and make s390-virtio use the same mechanism
as the other transports do.

s390-virtio: Accommodate guests using virtqueues too early
Feature updates are not a synchronuous operation for the legacy
s390-virtio transport. This transport syncs the guest feature bits
(those from finalize) on the set_status hypercall. Before that qemu
thinks that features are zero, which means QEMU will misbehave, e.g.
it will not write the event index, even if the guest asks for it.
Let's detect the case where a kick happens before the driver is ready
and force sync the features.
With this workaround, it is now safe to switch to the common feature
bit handling code as used by all other transports.

qapi: Check for member name conflicts with a base class
Our type inheritance for both 'struct' and for flat 'union' merges
key/value pairs from the base class with those from the type in
question. Although the C code currently boxes things so that there
is a distinction between which member is referred to, the QMP wire
format does not allow passing a key more than once in a single
object. Besides, if we ever change the generated C code to not be
quite so boxy, we'd want to avoid duplicate member names there,
too.
Fix a testsuite entry added in an earlier patch, as well as adding
a couple more tests to ensure we have appropriate coverage. Ensure
that collisions are detected, regardless of whether there is a
difference in opinion on whether the member name is optional.

qapi: Support (subset of) \u escapes in strings
The handling of \ inside QAPI strings was less than ideal, and
really only worked JSON's \/, \\, \", and our extension of \'
(an obvious extension, when you realize we use '' instead of ""
for strings). For other things, like '\n', it resulted in a
literal 'n' instead of a newline.
Of course, at the moment, we really have no use for escaped
characters, as QAPI has to map to C identifiers, and we currently
support ASCII only for that. But down the road, we may add
support for default values for string parameters to a command
or struct; if that happens, it would be nice to correctly support
all JSON escape sequences, such as \n or \uXXXX. This gets us
closer, by supporting Unicode escapes in the ASCII range.
Since JSON does not require \OCTAL or \xXX escapes, and our QMP
implementation does not understand them either, I intentionally
reject it here, but it would be an easy addition if we desired it.
Likewise, intentionally refusing the NUL byte means we don't have
to worry about C strings being shorter than the qapi input.

qapi: Drop tests for inline nested structs
A future patch will be using a 'name':{dictionary} entry in the
QAPI schema to specify a default value for an optional argument;
but existing use of inline nested structs conflicts with that goal.
More precisely, a definition in the QAPI schema associates a name
with a set of properties:
Example 1: { 'struct': 'Foo', 'data': { MEMBERS... } }
associates the global name 'Foo' with properties (meta-type struct)
and MEMBERS...
Example 2: 'mumble': TYPE
within MEMBERS... above associates 'mumble' with properties (type
TYPE) and (optional false) within type Foo
The syntax of example 1 is extensible; if we need another property,
we add another name/value pair to the dictionary (such as
'base':TYPE). The syntax of example 2 is not extensible, because
the right hand side can only be a type.
We have used name encoding to add a property: "'*mumble': 'int'"
associates 'mumble' with (type int) and (optional true). Nice,
but doesn't scale. So the solution is to change our existing uses
to be syntactic sugar to an extensible form:
NAME: TYPE --> NAME: { 'type': TYPE, 'optional': false }
*ONAME: TYPE --> ONAME: { 'type': TYPE, 'optional': true }
This patch fixes the testsuite to avoid inline nested types, by
breaking the nesting into explicit types; it means that the type
is now boxed instead of unboxed in C code, but makes no difference
on the wire (and if desired, a later patch could change the
generator to not do so much boxing in C). When touching code to
add new allocations, also convert existing allocations to
consistently prefer typesafe g_new0 over g_malloc0 when a type
name is involved.

qapi: Prefer 'struct' over 'type' in generator
Referring to "type" as both a meta-type (built-in, enum, union,
alternate, or struct) and a specific type (the name that the
schema uses for declaring structs) is confusing. The confusion
is only made worse by the fact that the generator mostly already
refers to struct even when dealing with expr['type']. This
commit changes the generator to consistently refer to it as
struct everywhere, plus a single back-compat tweak that allows
accepting the existing .json files as-is, so that the meat of
this change is separate from the mindless churn of that change.
Fix the testsuite fallout for error messages that change, and
in some cases, become more legible. Improve comments to better
match our intentions where a struct (rather than any complex
type) is required. Note that in some cases, an error message
now refers to 'struct' while the schema still refers to 'type';
that will be cleaned up in the later commit to the schema.

qapi: More rigorous checking for type safety bypass
Now that we have a way to validate every type, we can also be
stricter about enforcing that callers that want to bypass
type safety in generated code. Prior to this patch, it didn't
matter what value was associated with the key 'gen', but it
looked odd that 'gen':'yes' could result in bypassing the
generated code. These changes also enforce the changes made
earlier in the series for documentation and consolidation of
using '**' as the wildcard type, as well as 'gen':false as the
canonical spelling for requesting type bypass.
Note that 'gen':false is a one-way switch away from the default;
we do not support 'gen':true (similar for 'success-response').
In practice, this doesn't matter.

qapi: Whitelist commands that don't return dictionary
...or an array of dictionaries. Although we have to cater to
existing commands, returning a non-dictionary means the command
is not extensible (no new name/value pairs can be added if more
information must be returned in parallel). By making the
whitelist explicit, any new command that falls foul of this
practice will have to be self-documenting, which will encourage
developers to either justify the action or rework the design to
use a dictionary after all.
It's a little bit sloppy that we share a single whitelist among
three clients (it's too permissive for each). If this is a
problem, a future patch could tighten things by having the
generator take the whitelist as an argument (as in
scripts/qapi-commands.py --legacy-returns=...), or by having
the generator output C code that requires explicit use of the
whitelist (as in:
#ifndef FROBNICATE_LEGACY_RETURN_OK
# error Command 'frobnicate' should return a dictionary
#endif
then having the callers define appropriate macros). But until
we need such fine-grained separation (if ever), this patch does
the job just fine.

qapi: Require valid names
Previous commits demonstrated that the generator overlooked various
bad naming situations:
- types, commands, and events need a valid name
- enum members must be valid names, when combined with prefix
- union and alternate branches cannot be marked optional
Valid upstream names match [a-zA-Z][a-zA-Z0-9_-]*; valid downstream
names match __[a-zA-Z][a-zA-Z0-9._-]*. Enumerations match the
weaker [a-zA-Z0-9._-]+ (in part thanks to QKeyCode picking an enum
that starts with a digit, which we can't change now due to
backwards compatibility). Rather than call out three separate
regex, this patch just uses a broader combination that allows both
upstream and downstream names, as well as a small hack that
realizes that any enum name is merely a suffix to an already valid
name prefix (that is, any enum name is valid if prepending _ fits
the normal rules).
We could reject new enumeration names beginning with a digit by
whitelisting existing exceptions. We could also be stricter
about the distinction between upstream names (no leading
underscore, no use of dot) and downstream (mandatory leading
double underscore), but it is probably not worth the bother.

qapi: More rigourous checking of types
Now that we know every expression is valid with regards to
its keys, we can add further tests that those keys refer to
valid types. With this patch, all uses of a type (the 'data':
of command, type, union, alternate, and event; the 'returns':
of command; the 'base': of type and union) must resolve to an
appropriate subset of metatypes declared by the current qapi
parse; this includes recursing into each member of a data
dictionary. Dealing with '**' and nested anonymous structs
will be done in later patches.
Update the testsuite to match improved output.

qapi: Add some type check tests
Demonstrate that the qapi generator silently parses confusing
types, which may cause other errors later on. Later patches
will update the expected results as the generator is made stricter.
Most of the new tests focus on blatant errors. But
returns-whitelist is a case where we have historically allowed
returning something other than a JSON object from particular
commands; we have to keep that behavior to avoid breaking clients,
but it would be nicer to avoid adding such commands in the future,
because any return that is not an (array of) object cannot be
easily extended if future qemu wants to return additional
information. The QMP protocol already documents that clients
should ignore unknown dictionary keys, but does not require
clients to have to handle more than one type of JSON object.

qapi: Unify type bypass and add tests
For a few QMP commands, we are forced to pass an arbitrary type
without tracking it properly in QAPI. Among the existing clients,
this unnamed type was spelled 'dict', 'visitor', and '**'; this
patch standardizes on '**', matching the documentation changes
earlier in the series.
Meanwhile, for the 'gen' key, we have been ignoring the value,
although the schema consistently used "'no'" ('success-response'
was hard-coded to checking for 'no'). But now that we can support
a literal "false" in the schema, we might as well use that rather
than ignoring the value or special-casing a random string. Note
that these are one-way switches (use of 'gen':true is not the same
as omitting 'gen'). Also, the use of '**' requires 'gen':false,
but the use of 'gen':false does not mandate the use of '**'.
There is no difference to the generated code. Add some tests on
what we'd like to guarantee, although it will take later patches
to clean up test results and actually enforce the use of a bool
parameter.

qapi: Allow true, false and null in schema json
In the near term, we will use it for a sensible-looking
'gen':false inside command declarations, instead of the
current ugly 'gen':'no'.
In the long term, it will allow conversion from shorthand
with defaults mentioned only in side-band documentation:
'data':{'*flag':'bool', '*string':'str'}
into an explicit default value documentation, as in:
'data':{'flag':{'type':'bool', 'optional':true, 'default':true},
'string':{'type':'str', 'optional':true, 'default':null}}
We still don't parse integer values (also necessary before
we can allow explicit defaults), but that can come in a later
series.
Update the testsuite to match an improved error message.

qapi: Better error messages for duplicated expressions
The previous commit demonstrated that the generator overlooked
duplicate expressions:
- a complex type or command reusing a built-in type name
- redeclaration of a type name, whether by the same or different
metatype
- redeclaration of a command or event
- collision of a type with implicit 'Kind' enum for a union
- collision with an implicit MAX enum constant
Since the c_type() function in the generator treats all names
as being in the same namespace, this patch adds a global array
to track all known names and their source, to prevent collisions
before it can cause further problems. While valid .json files
won't trigger any of these cases, we might as well be nicer to
developers that make a typo while trying to add new QAPI code.

qapi: Better error messages for bad expressions
The previous commit demonstrated that the generator overlooked some
fairly basic broken expressions:
- missing metataype
- metatype key has a non-string value
- unknown key in relation to the metatype
- conflicting metatype (this patch treats the second metatype as an
unknown key of the first key visited, which is not necessarily the
first key the user typed)
Add check_keys to cover these situations, and update testcases to
match. A couple other tests (enum-missing-data, indented-expr) had
to change since the validation added here occurs so early.
Conversely, changes to ident-with-escape results show that we still
have problems where our handling of escape sequences differs from
true JSON, which will matter down the road if we allow arbitrary
default string values for optional parameters (but for now is not
too bad, as we currently can avoid unicode escaping as we don't
need to represent anything beyond C identifier material).
While valid .json files won't trigger any of these cases, we might
as well be nicer to developers that make a typo while trying to add
new QAPI code.

Note that in some cases, we reject bad QAPI merely because our
pseudo-JSON parser does not yet know how to parse numbers. This
series does not address that, but when a later series adds support
for numeric defaults of integer fields, the testsuite will ensure
that we don't lose the error (and hopefully that the error
message quality is improved).

qapi: Segregate anonymous unions into alternates in generator
Special-casing 'discriminator == {}' for handling anonymous unions
is getting awkward; since this particular type is not always a
dictionary on the wire, it is easier to treat it as a completely
different class of type, "alternate", so that if a type is listed
in the union_types array, we know it is not an anonymous union.
This patch just further segregates union handling, to make sure that
anonymous unions are not stored in union_types, and splitting up
check_union() into separate functions. A future patch will change
the qapi grammar, and having the segregation already in place will
make it easier to deal with the distinct meta-type.

Demonstrate that the qapi generator doesn't deal well with unions

Of particular note, qapi-code-gen.txt documents 'base' only for
flat unions, but the tests here demonstrate that we currently allow
a 'base' to a simple union, although it is exercised only in the
testsuite. Later patches will remove this undocumented feature, to
give us more flexibility in adding other future extensions to union
types. For example, one possible extension is the idea of a
type-safe simple enum, where added fields tie the discriminator to
a user-defined enum type rather than creating an implicit enum from
the names in 'data'. But adding such safety on top of a simple
enum with a base type could look ambiguous with a flat enum;
besides, the documentation also mentions how any simple union can
be represented by an equivalent flat union. So it will be simpler
to just outlaw support for something we aren't using.

qapi: Add copyright declaration on docs
While our top-level COPYING with its GPLv2+ license applies to
any documentation file that omits explicit instructions, these
days it's better to be a good example of calling out our
intentions. Correct use of GPL requires the use of a copyright
statement, so I'm adding notice to two QAPI documents, by
attributing these files to the initial authors and major
contributors. I used:
$ git blame --line-porcelain $file \
| sed -n 's/^author //p' | sort | uniq -c | sort -rn
to determine authorship of these two files. qmp-spec.txt blames
entirely to Red Hat (easy, since my contribution falls in that
category); while qapi-code-gen.txt has multiple contributors
representing multiple entities. But since it was originally
supplied by Michael Roth, the notice I added there copies the
notice he has used in other files. As there is no intended
change in license from the implicit one previously present from
the top level, I have not bothered to CC other contributors;
if we want to weaken things to something looser (such as LGPL)
so that there is no question that someone re-implementing the
spec is not forced to use GPL, that would be a different commit.

Enable NVMe start controller for Windows guest.
Windows seems to send two separate calls to NVMe controller configuration. The
first sends configuration info and the second the enable bit. I couldn't
enable the Windows 8.1 in-box NVMe driver with base Qemu. I made the
following change to store the configuration data and then handle enable and
NVMe driver works on Windows 8.1.
I am not a Windows expert and I'm not entirely sure this is the correct
approach. I'm offering it for anyone who wishes to use NVMe on Windows 8.1
using Qemu.
I have tested this change with Linux and Windows guests with NVMe devices.

kvm: better advice for failed s390x startup
If KVM_CREATE failed on s390x, we print a hint to enable the switch_amode
kernel parameter. This only applies to old kernels, and only if the
error was -EINVAL. Moreover, with new kernels, the most likely reason
for -EINVAL is that pgstes were not enabled.
Let's update the error message to give a better hint on where things
may need fixing.

s390x/kvm: Support access register mode for KVM_S390_MEM_OP ioctl
Access register mode is one of the modes that control dynamic address
translation. In this mode the address space is specified by values of
the access registers. The effective address-space-control element is
obtained from the result of the access register translation. See
the "Access-Register Introduction" section of the chapter 5 "Program
Execution" in "Principles of Operations" for more details.
When the CPU is in AR mode, the s390_cpu_virt_mem_rw() function must
know which access register number to use for address translation.
This patch does several things:
- add new parameter 'uint8_t ar' to that function
- decode ar number from intercepted instructions
- pass the ar number to s390_cpu_virt_mem_rw(), which in turn passes it
to the KVM_S390_MEM_OP ioctl.

s390x/kvm: Put vm name, extended name and UUID into STSI322 SYSIB
KVM prefills the SYSIB, returned by STSI 3.2.2. This patch allows
userspace to intercept execution, and fill in the values, that are
known to qemu: machine name (8 chars), extended machine name (256
chars), extended machine name encoding (equals 2 for UTF-8) and UUID.
STSI322 qemu handler also finds a highest virtualization level in
level-3 virtualization stack that doesn't support Extended Names
(Ext Name delimiter) and propagates zero Ext Name to all levels below,
because this level is not capable of managing Extended Names of lower
levels.

nbd/trivial: fix type cast for ioctl
This fixes ioctl behavior on powerpc e6500 platforms with 64bit kernel and 32bit
userspace. The current type cast has no effect there and the value passed to the
kernel is still 0. Probably an issue related to the compiler, since I'm assuming
the same configuration works on a similar setup on x86.
Also ensure consistency with previous type cast in TRACE message.

Makefile.target: prepend $libs_softmmu to $LIBS
I discovered a problem when trying to build QEMU statically with gcc.
libm is an element of LIBS while libpixman-1 is an element in
libs_softmmu. Libpixman references functions in libm, so the original
ordering makes linking fail.
This fix is to reorder $libs_softmmu and $LIBS to make -lm appear after
-lpixman-1. However I'm not quite sure if this is the right fix, hence
the RFC tag.
Normally QEMU is built with c++ compiler which happens to link in libm
(at least this is the case with g++), so building QEMU statically
normally just works and nobody notices this issue.

configure: Add support for tcmalloc
This adds "--enable-tcmalloc" and "--disable-tcmalloc" to allow linking
to libtcmalloc from gperftools.
tcmalloc is a malloc implementation that works well with threads and is
fast, so it is good for performance.
It is disabled by default, because the MALLOC_PERTURB_ flag we use in
tests doesn't work with tcmalloc. However we can enable tcmalloc
specific heap checker and profilers later.
An IOPS gain can be observed with virtio-blk-dataplane, other parts of
QEMU will directly benefit from it as well:

This is useful when we want to send commands that will trigger

Sometimes the event responses may arrive even before the command
confirmation will show up, so it is convenient to leave the responses

vfio-pci: Reset workaround for AMD Bonaire and Hawaii GPUs
Somehow these GPUs manage not to respond to a PCI bus reset, removing
our primary mechanism for resetting graphics cards. The result is
that these devices typically work well for a single VM boot. If the
VM is rebooted or restarted, the guest driver is not able to init the
card from the dirty state, resulting in a blue screen for Windows
guests.
The workaround is to use a device specific reset. This is not 100%
reliable though since it depends on the incoming state of the device,
but it substantially improves the usability of these devices in a VM.

vfio-pci: Fix error path sign
This is an impossible error path due to the fact that we're reading a
kernel provided, rather than user provided link, which will certainly
always fit in PATH_MAX. Currently it returns a fixed 26 char path
plus %d group number, which typically maxes out at double digits.
However, the caller of the initfn certainly expects a less-than zero
return value on error, not just a non-zero value. Therefore we
should correct the sign here.

vfio-pci: Further fix BAR size overflow
In an analysis by Laszlo, the resulting type of our calculation for
the end of the MSI-X table, and thus the start of memory after the
table, is uint32_t. We're therefore not correctly preventing the
corner case overflow that we intended to fix here where a BAR >=4G
could place the MSI-X table to end exactly at the 4G boundary. The
MSI-X table offset is defined by the hardware spec to 32bits, so we
simply use a cast rather than changing data structure types. This
scenario is purely theoretically, typically the MSI-X table is located
at the front of the BAR.

virtio-scsi: Move DEFINE_VIRTIO_SCSI_FEATURES to virtio-scsi
So far virtio-scsi-device can't expose host features to guest while

The host features belong to the backends while virtio-scsi-pci,
virtio-scsi-s390 and virtio-scsi-ccw set the DEFINE_VIRTIO_SCSI_FEATURES
on transports. But they already have the ability to forward property
accesses to the backend child. So if we move the host features to
backends, it doesn't break the backwards compatibility for them and
make host features work while using virtio-mmio.

block/mirror: Always call block_job_sleep_ns()
The mirror block job is trying to take a clever shortcut if delay_ns is
0 and skips block_job_sleep_ns() in that case. But that function must be
called in every block job iteration, because otherwise it is for example
impossible to pause the job.

iotests: add QMP event waiting queue
A filter is added to allow callers to request very specific
events to be pulled from the event queue, while leaving undesired
events still in the stream.
This allows us to poll for completion data for multiple asynchronous
events in any arbitrary order.
A new timeout context is added to the qmp pull_event method's
wait parameter to allow tests to fail if they do not complete
within some expected period of time.
Also fixed is a bug in qmp.pull_event where we try to retrieve an event
from an empty list if we attempt to retrieve an event with wait=False
but no events have occurred.

We test growing and shrinking by different amounts:
- Less than the granularity
- Less than the granularity, but across a boundary
- Less than sizeof(unsigned long)
- Less than sizeof(unsigned long), but across a ulong boundary
- More than sizeof(unsigned long)

block: Add bitmap successors
A bitmap successor is an anonymous BdrvDirtyBitmap that is intended to
be created just prior to a sensitive operation (e.g. Incremental Backup)
that can either succeed or fail, but during the course of which we still
want a bitmap tracking writes.
On creating a successor, we "freeze" the parent bitmap which prevents
its deletion, enabling, anonymization, or creating a bitmap with the
same name.
On success, the parent bitmap can "abdicate" responsibility to the
successor, which will inherit its name. The successor will have been
tracking writes during the course of the backup operation. The parent
will be safely deleted.
On failure, we can "reclaim" the successor from the parent, unifying
them such that the resulting bitmap describes all writes occurring since
the last successful backup, for instance. Reclamation will thaw the
parent, but not explicitly re-enable it.
BdrvDirtyBitmap operations that target a single bitmap are protected
by assertions that the bitmap is not frozen and/or disabled.
BdrvDirtyBitmap operations that target a group of bitmaps, such as
bdrv_{set,reset}_dirty will ignore frozen/disabled drives with a
conditional instead.
Internal functions that enable/disable dirty bitmaps have assertions
added to them to prevent modifying frozen bitmaps.

block: Add bitmap disabled status
Add a status indicating the enabled/disabled state of the bitmap.
A bitmap is by default enabled, but you can lock the bitmap into
a read-only state by setting disabled = true.
A previous version of this patch added a QMP interface for changing
the state of the bitmap, but it has since been removed for now until
a use case emerges where this state must be revealed to the user.
The disabled state WILL be used internally for bitmap migration and
bitmap persistence.

hbitmap: add hbitmap_merge
We add a bitmap merge operation to assist in error cases
where we wish to combine two bitmaps together.
This is algorithmically O(bits) provided HBITMAP_LEVELS remains
constant. For a full bitmap on a 64bit machine:
sum(bits/64^k, k, 0, HBITMAP_LEVELS) ~= 1.01587 * bits
We may be able to improve running speed for particularly sparse
bitmaps by using iterators, but the running time for dense maps
will be worse.
We present the simpler solution first, and we can refine it later
if needed.

qmp: Add block-dirty-bitmap-add and block-dirty-bitmap-remove
The new command pair is added to manage a user created dirty bitmap. The
dirty bitmap's name is mandatory and must be unique for the same device,
but different devices can have bitmaps with the same names.
The granularity is an optional field. If it is not specified, we will
choose a default granularity based on the cluster size if available,
clamped to between 4K and 64K to mirror how the 'mirror' code was
already choosing granularity. If we do not have cluster size info
available, we choose 64K. This code has been factored out into a helper
shared with block/mirror.
This patch also introduces the 'block_dirty_bitmap_lookup' helper,
which takes a device name and a dirty bitmap name and validates the
lookup, returning NULL and setting errp if there is a problem with
either field. This helper will be re-used in future patches in this
series.
The types added to block-core.json will be re-used in future patches
in this series, see:

qmp: fill in the image field in BlockDeviceInfo
The image field in BlockDeviceInfo is supposed to contain an ImageInfo
object. However that is being filled in by bdrv_query_info(), not by
bdrv_block_device_info(), which is where BlockDeviceInfo is actually
created.
Anyone calling bdrv_block_device_info() directly will get a null image
field. As a consequence of this, the HMP command 'info block -n -v'
crashes QEMU.
This patch moves the code that fills in that field from
bdrv_query_info() to bdrv_block_device_info().

block: use bdrv_get_device_or_node_name() in error messages
There are several error messages that identify a BlockDriverState by

In those cases we should use bdrv_get_device_or_node_name() to fall
back to the node name and produce a more meaningful message. The

block: avoid unnecessary bottom halves
bdrv_aio_* APIs can use coroutines to achieve asynchronicity. However,
the coroutine may terminate without having yielded back to the caller
(for example because of something that invokes a nested event loop,
or because the coroutine is doing nothing at all). In this case,
the bdrv_aio_* API must delay the completion to the next iteration
of the main loop, because bdrv_aio_* will never invoke the callback
before returning.
This can be done with a bottom half, and indeed bdrv_aio_* is always
using one for simplicity. It is possible to gain some performance
(~3%) by avoiding this in the common case. A new field in the
BlockAIOCBCoroutine struct is set to true until the first time the
corotine has yielded to its creator, and completion goes through a
new function bdrv_co_complete. If the flag is false, bdrv_co_complete
invokes the callback immediately. If it is true, the caller will
notice that the coroutine has completed and schedule the bottom
half itself.

blockjob: Allow nested pause
This patch changes block_job_pause to increase the pause counter and
block_job_resume to decrease it.
The counter will allow calling block_job_pause/block_job_resume
unconditionally on a job when we need to suspend the IO temporarily.
From now on, each block_job_resume must be paired with a block_job_pause
to keep the counter balanced.
The user pause from QMP or HMP will only trigger block_job_pause once
until it's resumed, this is achieved by adding a user_paused flag in
BlockJob.
One occurrence of block_job_resume in mirror_complete is replaced with
block_job_enter which does what is necessary.
In block_job_cancel, the cancel flag is good enough to instruct
coroutines to quit loop, so use block_job_enter to replace the unpaired
block_job_resume.
Upon block job IO error, user is notified about the entering to the
pause state, so this pause belongs to user pause, set the flag
accordingly and expect a matching QMP resume.

qemu-img convert: Rewrite copying logic
The implementation of qemu-img convert is (a) messy, (b) buggy, and
(c) less efficient than possible. The changes required to beat some
sense into it are massive enough that incremental changes would only
make my and the reviewers' life harder. So throw it away and reimplement
it from scratch.
Let me give some examples what I mean by messy, buggy and inefficient:
(a) The copying logic of qemu-img convert has two separate branches for
compressed and normal target images, which roughly do the same -
except for a little code that handles actual differences between
compressed and uncompressed images, and much more code that
implements just a different set of optimisations and bugs. This is
unnecessary code duplication, and makes the code for compressed
output (unsurprisingly) suffer from bitrot.
The code for uncompressed ouput is run twice to count the the total
length for the progress bar. In the first run it just takes a
shortcut and runs only half the loop, and when it's done, it toggles
a boolean, jumps out of the loop with a backwards goto and starts
over. Works, but pretty is something different.
(b) Converting while keeping a backing file (-B option) is broken in
several ways. This includes not writing to the image file if the
input has zero clusters or data filled with zeros (ignoring that the
backing file will be visible instead).
It also doesn't correctly limit every iteration of the copy loop to
sectors of the same status so that too many sectors may be copied to
in the target image. For -B this gives an unexpected result, for
other images it just does more work than necessary.
Conversion with a compressed target completely ignores any target
backing file.
(c) qemu-img convert skips reading and writing an area if it knows from
metadata that copying isn't needed (except for the bug mentioned
above that ignores a status change in some cases). It does, however,
read from the source even if it knows that it will read zeros, and
then search for non-zero bytes in the read buffer, if it's possible
that a write might be needed.
This reimplementation of the copying core reorganises the code to remove
the duplication and have a much more obvious code flow, by essentially
splitting the copy iteration loop into three parts:
1. Find the number of contiguous sectors of the same status at the
current offset (This can also be called in a separate loop before the
copying loop in order to determine the total sectors for the progress
bar.)
2. Read sectors. If the status implies that there is no data there to
read (zero or unallocated cluster), don't do anything.
3. Write sectors depending on the status. If it's data, write it. If
we want the backing file to be visible (with -B), don't write it. If
it's zeroed, skip it if you can, otherwise use bdrv_write_zeroes() to
optimise the write at least where possible.

Because AioContext does not use contention callbacks anymore, the
unit test has to be changed.

aio-posix: move pollfds to thread-local storage
By using thread-local storage, aio_poll can stop using global data during
g_poll_ns. This will make it possible to drop callbacks from rfifolock.
[Moved npfd = 0 assignment to end of walking_handlers region as
suggested by Paolo. This resolves the assert(npfd == 0) assertion
failure in pollfds_cleanup().

block: Switch to host monotonic clock for IO throttling
Currently, throttle timers won't make any progress when VCPU is not
running, which would stall the request queue in utils, qtest, vm
suspending, and live migration, without special handling.
Block jobs are confusingly inconsistent between with and without
throttling: if user sets a bps limit, stops the vm, then start a block
job, the block job will not make any progress; in contrary, if user
unsets the bps limit, or if it's not set, the block job will run
normally.
After this patch, with the host clock, even if the VCPUs are stopped,
the throttle queues will be processed.
This patch also enables potential to add throttle to bdrv_drain_all.
Currently all requests are drained immediately. In other words whenever
it is called, IO throttling goes ineffective (examples: system reset,
migration and many block job operations.). This is a loophole that guest
could exploit. If we use the host clock, we can later just trust the
nested poll. This could be done on top.
Note that for qemu-iotests case 093, which uses qtest, we still keep vm
clock so the script can control the clock stepping in order to be
deterministic.

os-win32: drop ffs(3) prototype
The lack of ffs(3) in the MinGW headers is a hint that we shouldn't rely
on it. MinGW 4.9.2 does not make it available for linking when QEMU's
./configure --enable-debug is used (release builds are fine though).
Now that all QEMU code has been switched to ctz32() there is no need for
ffs(3).

sd: convert sd_normal_command() ffs(3) call to ctz32()
ffs() cannot be replaced with ctz32() when the argument might be zero,
because ffs(0) returns 0 while ctz32(0) returns 32.
The ffs(3) call in sd_normal_command() is a special case though. It can
be converted to ctz32() + 1 because the argument is never zero:
if (!(req.arg >> 8) || (req.arg >> (ctz32(req.arg & ~0xff) + 1))) {

bt-sdp: fix broken uuids power-of-2 calculation
The binary search in sdp_uuid_match() only works when the number of
elements to search is a power of two.
lo = record->uuid;
hi = record->uuids;
while (hi >>= 1)
if (lo[hi] <= val)
lo += hi;
return *lo == val;
I noticed that the record->uuids calculation in
sdp_service_record_build() was suspect:
record->uuids = 1 << ffs(record->uuids - 1);
Unlike most ffs(val) - 1 users, the expression is ffs(val - 1)!
Actually ffs() is the wrong function to use for power-of-2. Use
pow2ceil() to achieve the correct effect. Now the record->uuid[] array
is sized correctly and the binary search in sdp_uuid_match() should
work.
I'm not sure how to run/test this code.

savevm: create snapshot failed when id_str already exists
The command "virsh create" will fail in such condition: vm has two
disks: vda and vdb. vda has snapshot s1 with id "1", vdb doesn't have
s1 but has snapshot s2 with id "1". When we want to run command "virsh
create s1", del_existing_snapshots() only deletes s1 in vda, and
bdrv_snapshot_create() tries to create vdb's snapshot s1 with id "1",
but id "1" alreay exists in vdb with name "s2"!
The simplest way is call find_new_snapshot_id() unconditionally.

pci: remove hard-coded bar size in msix_init_exclusive_bar()
This patch lets msix_init_exclusive_bar() can calculate the bar and
pba size based on the number of MSI-X vectors other than using a
hard-coded limit 4096. This is needed to allow device to have more
than 128 MSI_X vectors. To keep migration compatibility, keep using
4096 as bar size and 2048 for pba offset.
Notes: We don't care about the case that using vectors > 128 for
legacy machine type. Since we limit the queue max to 64, so vectors >=
65 is meaningless.
Virtio device will be the first user for this.

virtio-pci: speedup MSI-X masking and unmasking
This patch tries to speed up the MSI-X masking and unmasking through
the mapping between vector and queues. With this patch it will there's
no need to go through all possible virtqueues, which may help to
reduce the time spent when doing MSI-X masking/unmasking a single
vector when more than hundreds or even thousands of virtqueues were
supported.
Tested with 80 queue pairs virito-net-pci by changing the smp affinity
in the background and doing netperf in the same time:
Before the patch:
5711.70 Gbits/sec
After the patch:
6830.98 Gbits/sec
About 19.6% improvements in throughput.

virtio: introduce vector to virtqueues mapping
Currently we will try to traverse all virtqueues to find a subset that
using a specific vector. This is sub optimal when we will support
hundreds or even thousands of virtqueues. So this patch introduces a
method which could be used by transport to get all virtqueues that
using a same vector. This is done through QLISTs and the number of
QLISTs was queried through a transport specific method. When guest
setting vectors, the virtqueue will be linked and helpers for traverse
the list was also introduced.
The first user will be virtio pci which will use this to speed up
MSI-X masking and unmasking handling.

ioport: reserve the whole range of an I/O port in the AddressSpace
When an I/O port is more than 1 byte long, ioport.c is currently
creating "short" regions, for example 0x1ce-0x1ce for the 16-bit
Bochs index port. When I/O ports are memory mapped, and thus
accessed via a subpage_ops memory region, subpage_accepts gets
confused because it finds a hole at 0x1cf and rejects the access.
In order to fix this, modify registration of the region to cover
the whole size of the I/O port. Attempts to access an invalid
port will be blocked by find_portio returning NULL.
This only affects the VBE DISPI regions. For all other cases,
the MemoryRegionPortio entries for 2- or 4-byte accesses overlap
an entry for 1-byte accesses, thus the size of the memory region
is not affected.

ioport: loosen assertions on emulation of 16-bit ports
Right now, ioport.c assumes that the entire range specified with
MemoryRegionPortio includes a region with size == 1. This however
is not true for the VBE DISPI ports, which are 16-bit only. The
next patch will make these regions' length equal to two, which can
cause the assertions to trigger. Replace them with simple conditionals.
Also, ioport.c will emulate a 16-bit ioport with two distinct reads
or writes, even if one of the two accesses is out of the bounds given
by the MemoryRegionPortio array. Do not do this anymore, instead
discard writes to the incorrect register and read it as all-ones.
This ensures that the mrp->read and mrp->write callbacks get an
in-range ioport number.

exec: Notify cpu_register_map_client caller if the bounce buffer is available
The caller's workflow is like
if (!address_space_map()) {
...
cpu_register_map_client();
}
If bounce buffer became available after address_space_map() but before
cpu_register_map_client(), the caller could miss it and has to wait for the
next bounce buffer notify, which may never happen in the worse case.
Just notify the list in cpu_register_map_client().

monitor: Make client_migrate_info synchronous
Live migration with spice works like this today:
(1) client_migrate_info monitor cmd
(2) spice server notifies client, client connects to target host.
(3) qemu waits until spice client connect is finished.
(4) send over vmstate (i.e. main part of live migration).
(5) spice handover to target host.
(3) is implemented by making client_migrate_info a async monitor
command. This is the only async monitor command we have.
The original reason to implement this dance was that qemu did not accept
new tcp connections while the incoming migration was running, so (2) and
(4) could not be done in parallel. That issue was fixed long ago though.
Qemu version 1.3.0 (released Dec 2012) and newer happily accept tcp
connects while the incoming migration runs.
Time to drop step (3). This patch does exactly that, by making the
monitor command synchronous and removing the code needed to handle the
async monitor command in ui/spice-core.c

memory: Define API for MemoryRegionOps to take attrs and return status
Define an API so that devices can register MemoryRegionOps whose read
and write callback functions are passed an arbitrary pointer to some
transaction attributes and can return a success-or-failure status code.
This will allow us to model devices which:
* behave differently for ARM Secure/NonSecure memory accesses
* behave differently for privileged/unprivileged accesses
* may return a transaction failure (causing a guest exception)
for erroneous accesses
This patch defines the new API and plumbs the attributes parameter through
to the memory.c public level functions io_mem_read() and io_mem_write(),
where it is currently dummied out.
The success/failure response indication is also propagated out to
io_mem_read() and io_mem_write(), which retain the old-style
boolean true-for-error return.

qmp-commands: fix incorrect uses of ":O" specifier
As far as the QMP parser is concerned, neither the 'O' nor the 'q' format specifiers
put any constraint on the command. However, there are two differences:
1) from a documentation point of view 'O' says that this command takes
a dictionary. The dictionary will be converted to QemuOpts in the
handler to match the corresponding HMP command.
2) 'O' sets QMP_ACCEPT_UNKNOWNS, resulting in the command accepting invalid
extra arguments. For example the following is accepted:
{ "execute": "send-key",
"arguments": { "keys": [ { "type": "qcode", "data": "ctrl" },
{ "type": "qcode", "data": "alt" },
{ "type": "qcode", "data": "delete" } ], "foo": "bar" } }
Neither send-key nor migrate-set-capabilities take a QemuOpts-like
dictionary; they take an array of dictionaries. And neither command
really wants to have extra unknown arguments. Thus, the right
specifier to use in this case is 'q'; with this patch the above
command fails with
{"error": {"class": "GenericError", "desc": "Invalid parameter 'foo'"}}
as intended.

balloon: improve error msg when adding second device
A VM supports only one balloon device, but due to several changes
in infrastructure the error message got messed up when trying
to add a second device. Fix it.
Before this fix
Command-line:
qemu-qmp: -device virtio-balloon-pci,id=balloon0: Another balloon device already registered
qemu-qmp: -device virtio-balloon-pci,id=balloon0: Adding balloon handler failed
qemu-qmp: -device virtio-balloon-pci,id=balloon0: Device 'virtio-balloon-pci' could not be initialized
HMP:

{
"error": {

}
}
After this fix
Command-line:
qemu-qmp: -device virtio-balloon-pci,id=balloon0: Only one balloon device is supported
qemu-qmp: -device virtio-balloon-pci,id=balloon0: Device 'virtio-balloon-pci' could not be initialized
HMP:

hmp: fix crash in 'info block -n -v'
The image field in BlockDeviceInfo should never be null, however
bdrv_block_device_info() is not filling it in.
This makes the 'info block -n -v' command crash QEMU.
The proper solution is probably to move the relevant code from
bdrv_query_info() to bdrv_block_device_info(), but since we're too
close to the release for that this simpler workaround solves the
crash.

target-ppc: don't invalidate msr MSR_HVB bit in cpu_post_load
The invalidation code introduced in commit 2360b works by inverting most bits
of env->msr to ensure that hreg_store_msr() will forcibly update the CPU env
state to reflect the new msr value post-migration. Unfortunately
hreg_store_msr() is called with alter_hv set to 0 which preserves the MSR_HVB
state from the CPU env which is now the opposite value to what it should be.
Ensure that we don't invalidate the msr MSR_HVB bit during cpu_post_load so
that the correct value is restored. This fixes suspend/resume for PPC64.

tcg/tcg-op.c: Fix ld/st of 64 bit values on 32-bit bigendian hosts
Commit 951c6300f7 out-of-lined the 32-bit-host versions of
tcg_gen_{ld,st}_i64, but in the process it inadvertently changed
an #ifdef HOST_WORDS_BIGENDIAN to #ifdef TCG_TARGET_WORDS_BIGENDIAN.
Since the latter doesn't get defined anywhere this meant we always
took the "LE host" codepath, and stored the two halves of the value
in the wrong order on BE hosts. This typically breaks any 64-bit
guest on a 32-bit BE host completely, and will have possibly more
subtle effects even for 32-bit guests.
Switch the ifdef back to HOST_WORDS_BIGENDIAN.

block/iscsi: handle zero events from iscsi_which_events
newer libiscsi versions may return zero events from iscsi_which_events.
In this case iscsi_service will return immediately without any progress.
To avoid busy waiting for iscsi_which_events to change we deregister all
read and write handlers in this case and schedule a timer to periodically
check iscsi_which_events for changed events.
Next libiscsi version will introduce async reconnects and zero events
are returned while libiscsi is waiting for a reconnect retry.

aio: strengthen memory barriers for bottom half scheduling
There are two problems with memory barriers in async.c. The fix is
to use atomic_xchg in order to achieve sequential consistency between
the scheduling of a bottom half and the corresponding execution.
First, if bh->scheduled is already 1 in qemu_bh_schedule, QEMU does
not execute a memory barrier to order any writes needed by the callback
before the read of bh->scheduled. If the other side sees req->state as
THREAD_ACTIVE, the callback is not invoked and you get deadlock.
Second, the memory barrier in aio_bh_poll is too weak. Without this
patch, it is possible that bh->scheduled = 0 is not "published" until
after the callback has returned. Another thread wants to schedule the
bottom half, but it sees bh->scheduled = 1 and does nothing. This causes
a lost wakeup. The memory barrier should have been changed to smp_mb()
in commit 924fe12 (aio: fix qemu_bh_schedule() bh->ctx race condition,
2014-06-03) together with qemu_bh_schedule()'s. Guess who reviewed
that patch?
Both of these involve a store and a load, so they are reproducible on
x86_64 as well. It is however much easier on aarch64, where the
libguestfs test suite triggers the bug fairly easily. Even there the
failure can go away or appear depending on compiler optimization level,
tracing options, or even kernel debugging options.
Paul Leveille however reported how to trigger the problem within 15
minutes on x86_64 as well. His (untested) recipe, reproduced here
for reference, is the following:
1) Qcow2 (or 3) is critical – raw files alone seem to avoid the problem.
2) Use “cache=directsync” rather than the default of
“cache=none” to make it happen easier.
3) Use a server with a write-back RAID controller to allow for rapid
IO rates.
4) Run a random-access load that (mostly) writes chunks to various
files on the virtual block device.
a. I use ‘diskload.exe c:25’, a Microsoft HCT load
generator, on Windows VMs.
b. Iometer can probably be configured to generate a similar load.
5) Run multiple VMs in parallel, against the same storage device,
to shake the failure out sooner.
6) IvyBridge and Haswell processors for certain; not sure about others.
A similar patch survived over 12 hours of testing, where an unpatched
QEMU would fail within 15 minutes.
This bug is, most likely, also the cause of failures in the libguestfs
testsuite on AArch64.
Thanks to Laszlo Ersek for initially reporting this bug, to Stefan
Hajnoczi for suggesting closer examination of qemu_bh_schedule, and to
Paul for providing test input and a prototype patch.

arm: memory: Replace memory_region_init_ram with memory_region_allocate_system_memory
Commit 0b183fc871:"memory: move mem_path handling to
memory_region_allocate_system_memory" split memory_region_init_ram and
memory_region_init_ram_from_file. Also it moved mem-path handling a step
up from memory_region_init_ram to memory_region_allocate_system_memory.
Therefore for any board that uses memory_region_init_ram directly,
-mem-path is not supported.
Fix this by replacing memory_region_init_ram with
memory_region_allocate_system_memory.

virtio-blk: correctly dirty guest memory
After qemu_iovec_destroy, the QEMUIOVector's size is zeroed and
the zero size ultimately is used to compute virtqueue_push's len
argument. Therefore, reads from virtio-blk devices did not
migrate their results correctly. (Writes were okay).
Save the size in virtio_blk_handle_request, and use it when the request
is completed.

qcow2: Fix header update with overridden backing file
In recent qemu versions, it is possible to override the backing file
name and format that is stored in the image file with values given at
runtime. In such cases, the temporary override could end up in the
image header if the qcow2 header was updated, while obviously correct
behaviour would be to leave the on-disk backing file path/format
unchanged.
Fix this and add a test case for it.

sysbus: Make devices picking up backends unavailable with -device
Device models aren't supposed to go on fishing expeditions for
backends. They should expose suitable properties for the user to set.
For onboard devices, board code sets them.
A number of sysbus devices pick up block backends in their init() /
instance_init() methods with drive_get_next() instead: sl-nand,
milkymist-memcard, pl181, generic-sdhci.
Likewise, a number of sysbus devices pick up character backends in
their init() / realize() methods with qemu_char_get_next_serial():
cadence_uart, digic-uart, etraxfs,serial, lm32-juart, lm32-uart,
milkymist-uart, pl011, stm32f2xx-usart, xlnx.xps-uartlite.
All these mistakes are already marked FIXME. See the commit that
added these FIXMEs for a more detailed explanation of what's wrong.
Fortunately, only machines ppce500 and pseries-* support -device with
sysbus devices, and none of the devices above is supported with these
machines.
Set cannot_instantiate_with_device_add_yet to preserve our luck.

hw: Mark device misusing nd_table[] FIXME
NICs defined with -net nic are for board initialization to wire up.
Board code examines nd_table[] to find them, and creates devices with
their qdev NIC properties set accordingly.
Except "allwinner-a10" goes on a fishing expedition for NIC
configuration instead of exposing the usual NIC properties for board
code to set: it uses nd_table[0] in its instance_init() method.
Picking up the first -net nic option's configuration that way works
when the device is created by board code. But it's inappropriate for
-device and device_add. Not only is it inconsistent with how the
other block device models work (they get their configuration from
properties "mac", "vlan", "netdev"), it breaks when nd_table[0] has
been picked up by the board or a previous -device / device_add
already.
Example:
$ qemu-system-arm -S -M cubieboard -device allwinner-a10
qemu-system-arm: -device allwinner-a10: Property 'allwinner-emac.netdev' can't take value 'hub0port0', it's in use
Aborted (core dumped)
It also breaks in other entertaining ways:
$ qemu-system-arm -M highbank -device allwinner-a10
qemu-system-arm: -device allwinner-a10: Unsupported NIC model: xgmac
$ qemu-system-arm -M highbank -net nic,model=allwinner-emac -device allwinner-a10

hw: Mark devices picking up char backends actively FIXME
Character devices defined with -serial and -parallel are for board
initialization to wire up. Board code examines serial_hds[] and
parallel_hds[] to find them, and creates devices with their qdev
chardev properties set accordingly.
Except a few devices go on a fishing expedition for a suitable backend
instead of exposing a chardev property for board code to set: they use
serial_hds[] (often via qemu_char_get_next_serial()) or parallel_hds[]
in their realize() or init() method to connect to a backend.
Picking up backends that way works when the devices are created by
board code. But it's inappropriate for -device or device_add. Not
only is it inconsistent with how the other characrer device models
work (they connect to a backend explicitly identified by a "chardev"
property), it breaks when the backend has been picked up by the board
or a previous -device / device_add already.
Example:
$ qemu-system-ppc64 -M bamboo -S -device i82378 -device pc87312 -device pc87312
qemu-system-ppc64: -device pc87312: Property 'isa-parallel.chardev' can't take value 'parallel0', it's in use

Drives defined with if!=none are for board initialization to wire up.
Board code calls drive_get() or similar to find them, and creates

Except a few devices go on a fishing expedition for a suitable backend

target-arm: kvm64 fix save/restore of SPSR regs
The current code was negatively indexing the cpu state array and not
synchronizing banked spsr register state with the current mode's spsr
state, causing occasional failures with migration.
Some munging is done to take care of the aarch64 mapping and also to
ensure the most current value of the spsr is updated to the banked
registers (relevant for KVM<->TCG migration).

This adds the saving and restore of the current Multi-Processing state

potential states for x86 we only use two for ARM. Either the process is
running or not. We then save this state into the cpu_powered TCG state

CVE-2015-1779: limit size of HTTP headers from websockets clients
CVE-2015-1779: incrementally decode websocket frames

Date: Mon Mar 23 22:58:22 2015 +0000
CVE-2015-1779: limit size of HTTP headers from websockets clients
The VNC server websockets decoder will read and buffer data from
websockets clients until it sees the end of the HTTP headers,
as indicated by \r\n\r\n. In theory this allows a malicious to
trick QEMU into consuming an arbitrary amount of RAM. In practice,
because QEMU runs g_strstr_len() across the buffered header data,
it will spend increasingly long burning CPU time searching for
the substring match and less & less time reading data. So while
this does cause arbitrary memory growth, the bigger problem is
that QEMU will be burning 100% of available CPU time.
A novnc websockets client typically sends headers of around
512 bytes in length. As such it is reasonable to place a 4096
byte limit on the amount of data buffered while searching for
the end of HTTP headers.

Date: Mon Mar 23 22:58:21 2015 +0000
CVE-2015-1779: incrementally decode websocket frames
The logic for decoding websocket frames wants to fully
decode the frame header and payload, before allowing the
VNC server to see any of the payload data. There is no
size limit on websocket payloads, so this allows a
malicious network client to consume 2^64 bytes in memory
in QEMU. It can trigger this denial of service before
the VNC server even performs any authentication.
The fix is to decode the header, and then incrementally
decode the payload data as it is needed. With this fix
the websocket decoder will allow at most 4k of data to
be buffered before decoding and processing payload.

rcu: do not create thread in pthread_atfork callback
If QEMU forks after the CPU threads have been created, qemu_mutex_lock_iothread
will not be able to do qemu_cpu_kick_thread. There is no solution other than
assuming that forks after the CPU threads have been created will end up in an
exec. Forks before the CPU threads have been created (such as -daemonize)
have to call rcu_after_fork manually.
Notably, the oxygen theme for GTK+ forks and shows a "No such process" error
without this patch.
This patch can be reverted once the iothread loses the "kick the TCG thread"
magic.
User-mode emulation does not use the iothread, so it can also call
rcu_after_fork.

AHCI: Protect cmd register
AHCI: Do not (re)map FB/CLB buffers while not running

AHCI: Protect cmd register
Many bits in the CMD register are supposed to be strictly read-only.
We should not be deleting them on every write.
As a side-effect: pay explicit attention to when a guest marks off
the FIS Receive or Start bits, and disable the status bits ourselves,
instead of letting them implicitly fall off.

AHCI: Do not (re)map FB/CLB buffers while not running
The FIS Receive Buffer and Command List Buffer pointers
should not be edited while the FIS receive engine or
Command Receive engines are running.
Currently, we attempt to re-map the buffers every time they
are adjusted, but while the AHCI engines are off, these registers
may contain stale values, so we should not attempt to re-map these
values until the engines are reactivated.

block: Fix unaligned zero write
If the zero write is not aligned, bdrv_co_do_pwritev will segfault
because of accessing to the NULL qiov passed in by bdrv_co_write_zeroes.
Fix this by allocating a local qiov in bdrv_co_do_pwritev if the request
is not aligned. (In this case the padding iovs are necessary anyway, so
it doesn't hurt.)
Also add a check at the end of bdrv_co_do_pwritev to clear the zero flag
if padding is involved.

exec: avoid possible overwriting of mmaped area in qemu_ram_remap
It is not necessary to munmap an area before remapping it with MAP_FIXED;
if the memory region specified by addr and len overlaps pages of any
existing mapping, then the overlapped part of the existing mapping will
be discarded.
On the other hand, if QEMU does munmap the pages, there is a small
probability that another mmap sneaks in and catches the just-freed
portion of the address space. In effect, munmap followed by
mmap(MAP_FIXED) is a use-after-free error, and Coverity flags it
as such. Fix it.

target-ppc: Remove POWER5+ v0.0 that never existed
IBM uses low 16bits to specify the chip version of a POWER CPU.
So there has never been an actual silicon with PVR = 0x003B0000.
The first silicon would have PVR 0x003B0100 but it is very unlikely
to find it in any machine shipped to any customer as it was too raw.
This removes CPU_POWERPC_POWER5P_v00 definition and changes
POWER5+ and POWERgs aliases (which are synonyms) to point to
POWER5+_v2.1 which can still be found in real machines.

This fixes potential runtime crashes and two warnings from Coverity.
The new error message does not add a prefix "qemu:" because that is
already done in function hw_error. It also starts with an uppercase
letter because that seems to be the mostly used form.

virtio-net: validate backend queue numbers against bus limitation
We don't validate the backend queue numbers against bus limitation,
this will easily crash qemu if it exceeds the limitation which will
hit the abort() in virtio_del_queue(). An example is trying to
starting a virtio-net device with 256 queues. E.g:
./qemu-system-x86_64 -netdev tap,id=hn0,queues=256 -device
virtio-net-pci,netdev=hn0
Fixing this by doing the validation and fail early.

virtio-serial: fix virtio config size
commit 9b70c1790acacae54d559d38ca69186a85040bb8
virtio-serial: switch to standard-headers
changes virtio_console_config size from 8 to 12 bytes:
it adds an optional 4 byte emerg_wr field.
As this crosses a power of two boundary, this changes the PCI BAR size,
which breaks migration compatibility with old qemu machine types.
It's probably a problem for other transports as well.
As a temporary fix, as we don't yet support this new field anyway,
simply make the config size smaller at init time.
Long terms we probably want something along the lines
of virtio_net_set_config_size.

cpus: Don't kick un-realized cpus.
following a464982499b2f637f6699e3d03e0a9d2e0b5288b, it's now possible for
there to be attempts to take the BQL before CPUs have been realized in
cases where a machine model inits peripherals before the first CPU.
BQL lock aquisition kicks the first_cpu, leading to a segfault if this
happens pre-realize. Guard the CPU kick routine to perform no action for
a CPU that doesn't exist or doesn't have a thread yet.
There was a fix to this with commit
6b49809c597331803ea941eadda813e5bb4e8fe2, but the check there misses
the case where the CPU has been inited and not realized. Strengthen the
check to make sure that the first_cpu has a thread (i.e. it is
realized) before allowing the kick.

i6300esb: Fix signed integer overflow
If the guest programs a sufficiently large timeout value an integer
overflow can occur in i6300esb_restart_timer(). e.g. if the maximum
possible timer preload value of 0xfffff is programmed then we end up with
the calculation:
timeout = get_ticks_per_sec() * (0xfffff << 15) / 33000000;
get_ticks_per_sec() returns 1000000000 (10^9) giving:
10^9 * (0xfffff * 2^15) == 0x1dcd632329b000000 (65 bits)
Obviously the division by 33MHz brings it back under 64-bits, but the
overflow has already occurred.
Since signed integer overflow has undefined behaviour in C, in theory this
could be arbitrarily bad. In practice, the overflowed value wraps around
to something negative, causing the watchdog to immediately expire, killing
the guest, which is still fairly bad.
The bug can be triggered by running a Linux guest, loading the i6300esb
driver with parameter "heartbeat=2046" and opening /dev/watchdog. The
watchdog will trigger as soon as the device is opened.
This patch corrects the problem by using muldiv64(), which effectively
allows a 128-bit intermediate value between the multiplication and
division.

i6300esb: Correct endiannness
The IO operations for the i6300esb watchdog timer are marked as
DEVICE_NATIVE_ENDIAN. This is not correct, and - as a PCI device - should
be DEVICE_LITTLE_ENDIAN.
This allows i6300esb to work on ppc targets (yes, using an Intel ICH
derived device on ppc is a bit odd, but the driver exists on the guest
and there's no more obviously suitable watchdog device).

fw_cfg: factor out initialization of FW_CFG_ID (rev. number)
The fw_cfg documentation says this of the revision key (0x0001, FW_CFG_ID):

arm/virt doesn't. It could be argued that that's an error in
"hw/arm/virt.c"; on the other hand, all of the other fw_cfg providing
boards set the interface version to 1 manually, despite the device
coming from the same, shared implementation. Therefore, instead of
adding
fw_cfg_add_i32(fw_cfg, FW_CFG_ID, 1);
to arm/virt, consolidate all such existing calls in the fw_cfg
initialization code.

rcu tests: fix compilation on 32-bit ppc
32-bit PPC cannot do atomic operations on long long. Inside the loops,
we are already using local counters that are summed at the end of
the run---with some exceptions (rcu_stress_count for rcutorture,
n_nodes for test-rcu-list): fix them to use the same technique.
For test-rcu-list, remove the mostly unused member "val" from the
list. Then, use a mutex to protect the global counts.
Performance does not matter there because every thread will only enter
the critical section once.
Remaining uses of atomic instructions are for ints or pointers.

This does not bother DMA, because DMA generally transfers
the entire SGList in one shot if it can.
PIO, on the other hand, tries to transfer just one sector

to fetch memory addresses.
Fix the memory address calculaton when we have an offset
by moving the offset addition OUTSIDE of the le64_to_cpu

linux-user/main.c: Remove redundant end_exclusive() in arm_kernel_cmpxchg64_helper()
start/end_exclusive() need be pairs, except the start_exclusive() in
stop_all_tasks() which is only used by force_sig(), which will be abort.
So at present, start_exclusive() in stop_all_task() need not be paired.
queue_signal() may call force_sig(), or return after kill pid (or queue
signal). If could return from queue_signal(), stop_all_task() would not
be called in time, the next end_exclusive() would be issue.
So in arm_kernel_cmpxchg64_helper() for ARM, need remove end_exclusive()
after queue_signal(). The related commit: "97cc756 linux-user: Implement
new ARM 64 bit cmpxchg kernel helper".

target-i386: Haswell-noTSX and Broadwell-noTSX
With the Intel microcode update that removed HLE and RTM, there will be
different kinds of Haswell and Broadwell CPUs out there: some that still
have the HLE and RTM features, and some that don't have the HLE and RTM
features. On both cases people may be willing to use the pc-*-2.3
machine-types.
So, to cover both cases, introduce Haswell-noTSX and Broadwell-noTSX CPU
models, for hosts that have Haswell and Broadwell CPUs without TSX support.

So instead of making the CPU model results confusing by making it depend

"Broadwell-noTSX" CPU models later, for people who have CPUs that don't

numa: Print warning if no node is assigned to a CPU
We need all possible CPUs (including hotplug ones) to be present in the
SRAT when QEMU starts. QEMU already does that correctly today, the only
problem is that when a CPU is omitted from the NUMA configuration, it is
silently assigned to node 0.
Check if all CPUs up to max_cpus are present in the NUMA configuration
and warn about missing CPUs.
Make it just a warning, to allow management software to be updated if
necessary. In the future we may make it a fatal error instead.
Command-line examples:
* Correct, no warning:
$ qemu-system-x86_64 -smp 2,maxcpus=4
$ qemu-system-x86_64 -smp 2,maxcpus=4 -numa node,cpus=0-3
* Incomplete, with warnings:
$ qemu-system-x86_64 -smp 2,maxcpus=4 -numa node,cpus=0
qemu-system-x86_64: warning: CPU(s) not present in any NUMA nodes: 1 2 3
qemu-system-x86_64: warning: All CPU(s) up to maxcpus should be described in NUMA config
$ qemu-system-x86_64 -smp 2,maxcpus=4 -numa node,cpus=0-2

pc: fix default VCPU to NUMA node mapping
Since commit
dd0247e0 pc: acpi: mark all possible CPUs as enabled in SRAT
Linux kernel actually tries to use CPU to Node mapping from
QEMU provided SRAT table instead of discarding it, and that
in some cases breaks build_sched_domains() which expects
sane mapping where cores/threads belonging to the same socket
are on the same NUMA node.
With current default round-robin mapping of VCPUs to nodes
guest ends-up with cores/threads belonging to the same socket
being on different NUMA nodes.
For example with following CLI:
qemu-system-x86_64 -m 4G \
-cpu Opteron_G3,vendor=AuthenticAMD \
-smp 5,sockets=1,cores=4,threads=1,maxcpus=8 \
-numa node,nodeid=0 -numa node,nodeid=1
2.6.32 based kernels will hang on boot due to incorrectly built
sched_group-s list in update_sd_lb_stats()
Replacing default mapping with a manual, where VCPUs belonging to
the same socket are on the same NUMA node, fixes the issue for
guests which can't handle nonsense topology i.e. changing CLI to:
-numa node,nodeid=0,cpus=0-3 -numa node,nodeid=1,cpus=4-7
So instead of simply scattering VCPUs around nodes, provide
callback to map the same socket VCPUs to the same NUMA node,
which is what guests would expect from a sane hardware/BIOS.

CPUs. Making guests confused wrt topology where cores from

Allow a machine to override default mapping by providing
MachineClass::cpu_index_to_socket_id()

virtio: serial: expose a 'guest_writable' callback for users
Users of virtio-serial may want to know when a port becomes writable. A
port can stop accepting writes if the guest port is open but not being
read from. In this case, data gets queued up in the virtqueue, and
after the vq is full, writes to the port do not succeed.
When the guest reads off a vq element, and adds a new one for the host
to put data in, we can tell users the port is available for more writes,
via the new ->guest_writable() callback.

raw-posix: Deprecate host floppy passthrough
Raise your hand if you have a physical floppy drive in a computer
you've powered on in 2015. Okay, I see we got a few weirdos in the
audience. That's okay, weirdos are welcome here.
Kidding aside, media change detection doesn't fully work, isn't going
to be fixed, and floppy passthrough just isn't earning its keep
anymore.
Deprecate block driver host_floppy now, so we can drop it after a
grace period.

hmp: Fix definition of command quit
The command handler is a union of two function types. If
cmd->user_print is set, handle_user_command() calls
cmd->mhandler.cmd_new(), else cmd->mhandler.cmd().
Command definitions must therefore either set both user_print() and
mhandler.cmd_new(), or only mhandler.cmd().
quit's sets user_print and mhandler.cmd(). handle_user_command()
calls hmp_quit() through mhandler.cmd_new() rather than
mhandler.cmd(), i.e. through a function pointer with a different type.
Broken in commit 7a7f325, v1.0.
Works in practice because hmp_quit() doesn't use its arguments, and
handle_user_command() ignores its function value.

address_space_translate_internal will clamp the *plen length argument
based on the size of the memory region being queried. The iommu walker
logic in addresss_space_translate was ignoring this by discarding the
post fn call value of *plen. Fix by just always using *plen as the

profiler: Reenable built-in profiler
2ed1ebcf6 "timer: replace time() with QEMU_CLOCK_HOST" broke compile
when configured with --enable-profiler. Turned out the profiler has been
broken for a while.
This does s/qemu_time/tcg_time/ as the profiler only works in a TCG mode.
This also fixes the compile error.
This changes profile_getclock() to return nanoseconds rather than
CPU ticks as the "profile" HMP command prints seconds and there is no
platform-independent way to get ticks-per-second rate.
Since TCG is quite slow and get_clock() returns nanoseconds (fine
enough), this should not affect precision much.
This removes unused qemu_time_start and tlb_flush_time.

target-mips: fix hflags modified in delay / forbidden slot
All instructions which may change hflags terminate tb. However, this doesn't
work if such an instruction is placed in delay or forbidden slot.
gen_branch() clears MIPS_HFLAG_BMASK in ctx->hflags and then generates code
to overwrite hflags with ctx->hflags, consequently we loose any execution-time
hflags modifications. For example, in the following scenario hflag related to
Status.CU1 will not be updated:
/* Set Status.CU1 in delay slot */
mfc0 $24, $12, 0
lui $25, 0x2000
or $25, $25, $24
b check_Status_CU1
mtc0 $25, $12, 0
With this change we clear MIPS_HFLAG_BMASK in execution-time hflags if
instruction in delay or forbidden slot wants to terminate tb for some reason
(i.e. ctx->bstate != BS_NONE).
Also, die early and loudly if "unknown branch" is encountered as this should
never happen.

ui: enforce TLS when using websockets server
When TLS is required, the primary VNC server considers it to be
mandatory. ie the server admin decides whether or not TLS is used,
and the client has to comply with this decision. The websockets
server, however, treated it as optional, allowing non-TLS clients
to connect to a server which had setup TLS. Thus enabling websockets
lowers the security of the VNC server leaving the admin no way to
enforce use of TLS.
This removes the code that allows non-TLS fallback in the websockets
server, so that if TLS is requested for VNC it is now mandatory for
both the primary VNC server and the websockets VNC server.

ui: fix setup of VNC websockets auth scheme with TLS
The way the websockets TLS code was integrated into the VNC server
made it essentially useless. The only time that the websockets TLS
support could be used is if the primary VNC server had its existing
TLS support disabled. ie QEMU had to be launched with:
# qemu -vnc localhost:1,websockets=5902,x509=/path/to/certs
Note the absence of the 'tls' flag. This is already a bug, because
the docs indicate that 'x509' is ignored unless 'tls' is given.
If the primary VNC server had TLS turned on via the 'tls' flag,
then this prevented the websockets TLS support from being used,
because it activates the VeNCrypt auth which would have resulted
in TLS being run over a TLS session. Of course no websockets VNC
client supported VeNCrypt so in practice, since the browser clients
cannot setup a nested TLS session over the main HTTPS connection,
so it would not even get past auth.
This patch causes us to decide our auth scheme separately for the
main VNC server vs the websockets VNC server. We take account of
the fact that if TLS is enabled, then the websockets client will
use https, so setting up VeNCrypt is thus redundant as it would
lead to nested TLS sessions.

ui: report error if user requests VNC option that is unsupported
If the VNC server is built without tls, sasl or websocket support
and the user requests one of these features, they are just silently
ignored. This is bad because it means the VNC server ends up running
in a configuration that is less secure than the user asked for.
It also leads to an tangled mass of preprocessor conditionals when
configuring the VNC server.
This ensures that the tls, sasl & websocket options are always

migration: Expose 'cancelling' status to user
'cancelling' status was introduced by commit 51cf4c1a, mainly to avoid a
possible start of a new migration process while the previous one still exists.
But we didn't expose this status to user, instead we returned the 'active' state.
Here, we expose it to the user (such as libvirt), 'cancelling' status only
occurs for a short window before the migration aborts, so for users,
if they cancel a migration process, it will observe 'cancelling' status
occasionally.
Testing revealed that with older libvirt (anything 1.2.13 or less) will
print an odd error message if the state is seen, but that the migration
is still properly cancelled. Newer libvirt will be patched to recognize
the new state without the odd error message.

usb/dev-storage: Fix QMP device_add missing encryption key failure
When the image is encrypted, QMP device_add creates the device, defers
actually attaching it to when the key becomes available, then returns
an error. This is wrong. device_add must either create the device
and succeed, or do nothing and fail.
The bug is in usb_msd_realize_storage(). It posts an error with
qerror_report_err(), and returns success. Device realization relies
on the return value, and completes. The QMP monitor, however, relies
on the posted error, and sends it in an error reply.
Reproducer:
$ qemu-system-x86_64 -nodefaults -display none -usb -qmp stdio -drive if=none,id=foo,file=geheim.qcow2
{"QMP": {"version": {"qemu": {"micro": 50, "minor": 2, "major": 2}, "package": ""}, "capabilities": []}}
{ "execute": "qmp_capabilities" }
{"return": {}}
{ "execute": "device_add", "arguments": { "driver": "usb-storage", "id": "bar", "drive": "foo" } }
{"error": {"class": "DeviceEncrypted", "desc": "'foo' (geheim.qcow2) is encrypted"}}
Even though we got an error back, the device got created just fine.
To demonstrate, let's unplug it again:
{"execute":"device_del","arguments": { "id": "bar" } }
{"timestamp": {"seconds": 1426003440, "microseconds": 237181}, "event": "DEVICE_DELETED", "data": {"path": "/machine/peripheral/bar/bar.0/legacy[0]"}}
{"timestamp": {"seconds": 1426003440, "microseconds": 238231}, "event": "DEVICE_DELETED", "data": {"device": "bar", "path": "/machine/peripheral/bar"}}
{"return": {}}
Fix by making usb_msd_realize_storage() fail properly.

monitor usb: Inline monitor_read_bdrv_key_start()'s first part
monitor_read_bdrv_key_start() does several things:
1. If no key is needed, call completion_cb() and succeed
2. If we're in QMP context, call qerror_report_err() and fail
3. Start reading the key in the monitor.
This is two things too many. Inline 1. and 2. into its callers
monitor_read_block_device_key() and usb_msd_realize_storage().
Since monitor_read_block_device_key() only ever runs in HMP context,
drop 2. there.

block/vpc: remove disabled code from get_sector_offset
The code to check the bitmap for the allocation status of each sector
has been "disabled by reason" ever since the vpc driver existed.
The reason might be that we might end up reading sector by sector
in vpc_read if we really used it. This would be a performance desaster.
The current code would furthermore not work if the disabled parts get
reactivated since vpc_read and vpc_write only use get_sector_offset to
check the allocation status of the first sector of a read/write operation.
This might lead to sectors incorrectly treated as zero in vpc_read and
to sectors getting allocated twice in vpc_write.

block/vpc: make calculate_geometry spec conform
The VHD spec [1] allows for total_sectors of 65535 x 16 x 255 (~127GB)
represented by a CHS geometry. If total_sectors is greater
than 65535 x 16 x 255 this geometry is set as a maximum.
Qemu, Hyper-V and disk2vhd use this special geometry as an indicator
to use the image current size from the footer as disk size.
This patch changes vpc_create to effectively calculate a CxHxS geometry
for the given image size if possible while rounding up if necessary.
If the image size is too big to be represented in CHS we set the maximum
and write the exact requested image size into the footer.
This partly reverts commit 258d2edb, but leaves support for >127G disks
intact.

vpc: Ignore geometry for large images
The CHS calculation as done per the VHD spec imposes a maximum image
size of ~127 GB. Real VHD images exist that are larger than that.
Apparently there are two separate non-standard ways to achieve this:
You could use more heads than the spec does - this is the option that
qemu-img create chooses.
However, other images exist where the geometry is set to the maximum
(65535/16/255), but the actual image size is larger. Until now, such
images are truncated at 127 GB when opening them with qemu.
This patch changes the vpc driver to ignore geometry in this case and
only trust the size field in the header.

qcow2: Respect new_block in alloc_refcount_block()
When choosing a new place for the refcount table, alloc_refcount_block()
tries to infer the number of clusters used so far from its argument
cluster_index (which comes from the idea that if any cluster with an
index greater than cluster_index was in use, the refcount table would
have to be big enough already to describe cluster_index).
However, there is a cluster that may be at or after cluster_index, and
which is not covered by the refcount structures, and that is the new
refcount block new_block. Therefore, it should be taken into account for
the blocks_used calculation.
Also, because new_block already describes (or is intended to describe)
cluster_index, we may not put the new refcount structures there.

block: Deprecate QCOW/QCOW2 encryption
We've steered users away from QCOW/QCOW2 encryption for a while,
because it's a flawed design (commit 136cd19 Describe flaws in
qcow/qcow2 encryption in the docs).
In addition to flawed crypto, we have comically bad usability, and
plain old bugs. Let me show you.
= Example images =
I'm going to use a raw image as backing file, and two QCOW2 images,
one encrypted, and one not:
$ qemu-img create -f raw backing.img 4m
Formatting 'backing.img', fmt=raw size=4194304
$ qemu-img create -f qcow2 -o encryption,backing_file=backing.img,backing_fmt=raw geheim.qcow2 4m
Formatting 'geheim.qcow2', fmt=qcow2 size=4194304 backing_file='backing.img' backing_fmt='raw' encryption=on cluster_size=65536 lazy_refcounts=off
$ qemu-img create -f qcow2 -o backing_file=backing.img,backing_fmt=raw normal.qcow2 4m
Formatting 'normal.qcow2', fmt=qcow2 size=4194304 backing_file='backing.img' backing_fmt='raw' encryption=off cluster_size=65536 lazy_refcounts=off
= Usability issues =
== Confusing startup ==
When no image is encrypted, and you don't give -S, QEMU starts the
guest immediately:
$ qemu-system-x86_64 -nodefaults -display none -monitor stdio normal.qcow2
QEMU 2.2.50 monitor - type 'help' for more information
(qemu) info status
VM status: running
But as soon as there's an encrypted image in play, the guest is *not*
started, with no notification whatsoever:
$ qemu-system-x86_64 -nodefaults -display none -monitor stdio geheim.qcow2
QEMU 2.2.50 monitor - type 'help' for more information
(qemu) info status
VM status: paused (prelaunch)
If the user figured out that he needs to type "cont" to enter his
keys, the confusion enters the next level: "cont" asks for at most
*one* key. If more are needed, it then silently does nothing. The
user has to type "cont" once per encrypted image:
$ qemu-system-x86_64 -nodefaults -display none -monitor stdio -drive if=none,file=geheim.qcow2 -drive if=none,file=geheim.qcow2
QEMU 2.2.50 monitor - type 'help' for more information
(qemu) info status
VM status: paused (prelaunch)
(qemu) c
none0 (geheim.qcow2) is encrypted.
Password: ******
(qemu) info status
VM status: paused (prelaunch)
(qemu) c
none1 (geheim.qcow2) is encrypted.
Password: ******
(qemu) info status
VM status: running
== Incorrect passwords not caught ==
All existing encryption schemes give you the GIGO treatment: garbage
password in, garbage data out. Guests usually refuse to mount
garbage, but other usage is prone to data loss.
== Need to stop the guest to add an encrypted image ==
$ qemu-system-x86_64 -nodefaults -display none -monitor stdio
QEMU 2.2.50 monitor - type 'help' for more information
(qemu) info status
VM status: running
(qemu) drive_add "" if=none,file=geheim.qcow2
Guest must be stopped for opening of encrypted image
(qemu) stop
(qemu) drive_add "" if=none,file=geheim.qcow2
OK
Commit c3adb58 added this restriction. Before, we could expose images
lacking an encryption key to guests, with potentially catastrophic
results. See also "Use without key is not always caught".
= Bugs =
== Use without key is not always caught ==
Encrypted images can be in an intermediate state "opened, but no key".
The weird startup behavior and the need to stop the guest are there to
ensure the guest isn't exposed to that state. But other things still
are!

with figuring out how to decrypt that again.

I guess this writes encrypted data into the unencrypted raw backing
image, effectively destroying it.
== QMP device_add of usb-storage fails when it shouldn't ==
When the image is encrypted, device_add creates the device, defers
actually attaching it to when the key becomes available, then fails.
This is wrong. device_add must either create the device and succeed,
or do nothing and fail.

This stuff is worse than useless, it's a trap for users.
If people become sufficiently interested in encrypted images to
contribute a cryptographically sane implementation for QCOW2 (or
whatever other format), then rewriting the necessary support around it
from scratch will likely be easier and yield better results than
fixing up the existing mess.
Let's deprecate the mess now, drop it after a grace period, and move
on.

pc: Disable vmdesc submission for old machines
Older PC machine types might by accident be backwards live migration compatible,
but with the new vmdesc self-describing blob in our live migration stream we
would break that compatibility.
Also users wouldn't expect massive behaviorial differences when updating to a
new version of QEMU while retaining their old machine type, especially not
potential breakage in tooling around live migration.
So disable vmdesc submission for old PC machine types.

migration: Read JSON VM description on incoming migration
One of the really nice things about the VM description format is that it goes
over the wire when live migration is happening. Unfortunately QEMU today closes
any socket once it sees VM_EOF coming, so we never give the VMDESC the chance to
actually land on the wire.
This patch makes QEMU read the description as well. This way we ensure that
anything wire tapping us in between will get the chance to also interpret the
stream.
Along the way we also fix virt tests that assume that number_bytes_sent on the
sender side is equal to number_bytes_read which was true before the VMDESC
patches and is true again with this patch.

linux-user: Access correct register for get/set_tls syscalls on ARM TZ CPUs
When support was added for TrustZone to ARM CPU emulation, we failed
to correctly update the support for the linux-user implementation of
the get/set_tls syscalls. This meant that accesses to the TPIDRURO
register via the syscalls were always using the non-secure copy of
the register even if native MRC/MCR accesses were using the secure
register. This inconsistency caused most binaries to segfault on startup
if the CPU type was explicitly set to one of the TZ-enabled ones like
cortex-a15. (The default "any" CPU doesn't have TZ enabled and so is
not affected.)
Use access_secure_reg() to determine whether we should be using
the secure or the nonsecure copy of TPIDRURO when emulating these
syscalls.

target-arm: Ignore low bit of PC in M-profile exception return
For the ARM M-profile cores, exception return pops various registers
including the PC from the stack. The architecture defines that if the
lowest bit in the new PC value is set (ie the PC is not halfword
aligned) then behaviour is UNPREDICTABLE. In practice hardware
implementations seem to simply ignore the low bit, and some buggy
RTOSes incorrectly rely on this. QEMU's behaviour was architecturally
permitted, but bringing QEMU into line with the hardware behaviour
allows more guest code to run. We log the situation as a guest error.
This was reported as LP:1428657.

target-arm: Fix handling of STM (user) with r15 in register list
The A32 encoding of LDM distinguishes LDM (user) from LDM (exception
return) based on whether r15 is in the register list. However for
STM (user) there is no equivalent distinction. We were incorrectly
treating "r15 in list" as indicating exception return for both LDM
and STM, with the result that an STM (user) involving r15 went into
an infinite loop. Fix this; note that the value stored for r15
in this case is the current PC regardless of our current mode.

target-arm: get_phys_addr_lpae: more xn control
This patch makes the following changes to the determination of
whether an address is executable, when translating addresses
using LPAE.
1. No longer assumes that PL0 can't execute when it can't read.
It can in AArch64, a difference from AArch32.
2. Use va_size == 64 to determine we're in AArch64, rather than
arm_feature(env, ARM_FEATURE_V8), which is insufficient.
3. Add additional XN determinants
- NS && is_secure && (SCR & SCR_SIF)
- WXN && (prot & PAGE_WRITE)
- AArch64: (prot_PL0 & PAGE_WRITE)
- AArch32: UWXN && (prot_PL0 & PAGE_WRITE)
- XN determination should also work in secure mode (untested)
- XN may even work in EL2 (currently impossible to test)
4. Cleans up the bloated PAGE_EXEC condition - by removing it.
The helper get_S1prot is introduced. It may even work in EL2,
when support for that comes, but, as the function name implies,
it only works for stage 1 translations.

target-arm: fix get_phys_addr_v6/SCTLR_AFE access check
Introduce simple_ap_to_rw_prot(), which has the same behavior as
ap_to_rw_prot(), but takes the 2-bit simple AP[2:1] instead of
the 3-bit AP[2:0]. Use this in get_phys_addr_v6 when SCTLR_AFE
is set, as that bit indicates we should be using the simple AP
format.
It's unlikely this path is getting used. I don't see CR_AFE
getting used by Linux, so possibly not. If it had been, then
the check would have been wrong for all but AP[2:1] = 0b11.
Anyway, this should fix it up, in case it ever does get used.

Instead of mixing access permission checking with access permissions
to page protection flags translation, just do the translation, and
leave it to the caller to check the protection flags against the access
type. Also rename to ap_to_rw_prot to better describe the new behavior.

s390x/config: Do not include full pci.mak
pci.mak includes a lot of devices - and most of them do not make
sense on s390x, like USB controllers or audio cards. These devices
also show up when running "qemu-system-s390x -device help" and thus
could raise the hope for the users that they could use these kind
of devices with qemu-system-s390x. To avoid this confusion, we
should not include pci.mak and rather include the bare minimum
manually instead.

Check for the aes_key_wrap and dea_key_wrap machine options and set the
appropriate KVM device attribute(s) to tell the kernel to enable or disable
the AES/DEA protected key functions for the guest domain.
This patch introduces two new machine options for indicating the state of
AES/DEA key wrapping functions. This controls whether the guest will
have access to the AES/DEA crypto functions.
aes_key_wrap="on | off" is changed to aes-key-wrap="on | off"
dea_key_wrap="on | off" is changed to dea-key-wrap="on | off"
Check for the aes-key-wrap and dea-key-wrap machine options and set the

So we encapsulate the common logic in a generic function.

s390x/kvm: Guest Migration TOD clock synchronization
Synchronizes the guest TOD clock across a migration by sending the guest TOD
clock value to the destination system. If the guest TOD clock is not preserved
across a migration then the guest's view of time will snap backwards if the
destination host clock is behind the source host clock. This will cause the
guest to hang immediately upon resuming on the destination system.

s390x: Replace unchecked qdev_init() by qdev_init_nofail()
s390_flic_init() is a helper to create and realize either
"s390-flic-kvm" or "s390-flic-qemu". When qdev_init() fails, it
complains to stderr and succeeds.
Except it can't actually fail, because the "s390-flic-qemu" is a dummy
without a realize method, and "s390-flic-kvm"'s realize can't fail,
even when the kernel device is really unavailable. Odd.
Replace qdev_init() by qdev_init_nofail() to make "can't fail" locally
obvious, and get rid of the unreachable error reporting.

net: synchronize net_host_device_remove with host_net_remove_completion
Using net_host_check_device is unnecessary. qemu_del_net_client asserts
for the non-peer case that it can only process NIC type NetClientStates,
and that assertion is valid for the peered case as well, so move it and
use the same check in net_host_device_remove. host_net_remove_completion
is already checking the type.

queue: fix QSLIST_INSERT_HEAD_ATOMIC race
There is a not-so-subtle race in QSLIST_INSERT_HEAD_ATOMIC.
Because atomic_cmpxchg returns the old value instead of a success flag,
QSLIST_INSERT_HEAD_ATOMIC was checking for success by comparing against
the second argument to atomic_cmpxchg. Unfortunately, this only works
if the second argument is a local or thread-local variable.
If it is in memory, it can be subject to common subexpression elimination
(and then everything's fine) or reloaded after the atomic_cmpxchg,
depending on the compiler's whims. If the latter happens, the race can
happen. A thread can sneak in, doing something on elm->field.sle_next
after the atomic_cmpxchg and before the comparison. This causes a wrong
failure, and then two threads are using "elm" at the same time. In the
case discovered by Christian, the sequence was likely something like this:
thread 1 | thread 2
QSLIST_INSERT_HEAD_ATOMIC |
atomic_cmpxchg succeeds |
elm added to list |
| steal release_pool
| QSLIST_REMOVE_HEAD
| elm removed from list
| ...
| QSLIST_INSERT_HEAD_ATOMIC
| (overwrites sle_next)
spurious failure |
atomic_cmpxchg succeeds |
elm added to list again |
|
steal release_pool |
QSLIST_REMOVE_HEAD |
elm removed again |
The last three steps could be done by a third thread as well.
A reproducer that failed in a matter of seconds is as follows:
- the guest has 32 VCPUs on a 28 core host (hyperthreading was enabled),
memory was 16G just to err on the safe side (the host has 64G, but hey
at least you need no s390)
- the guest has 24 null-aio virtio-blk devices using dataplane
(-object iothread,id=ioN -drive if=none,id=blkN,driver=null-aio,size=500G
-device virtio-blk-pci,iothread=ioN,drive=blkN)
- the guest also has a single network interface. It's only doing loopback
tests so slirp vs. tap and the model doesn't matter.
- the guest is running fio with the following script:
[global]

blocksize=16k

Float exception flags are not present in vmstate. Information they carry
is used only by softfloat caller who translates them into MIPS FCSR.Cause,
FCSR.Flags and then they are cleared. Therefore there is no need for saving

hw/arm/virt: fix cmdline parsing bug with CPU options and smp > 1
The recently introduced feature that allows 32 bit guests to be
executed under KVM on a 64-bit host incorrectly handles the case
where more than 1 cpu is specified using '-smp N'
For instance, this invocation of qemu
qemu-system-aarch64 -M virt -cpu cortex-a57,aarch64=off -smp 2
produces the following error
qemu-system-aarch64: Expected key=value format, found aarch64
which is caused by the destructive parsing performed by
cpu_common_parse_features(), resulting in subsequent attempts
to parse the CPU option string (for each additional CPU) to fail.
So duplicate the string before parsing it, and free it directly
afterwards.

virtio-serial: fix segfault on NULL port names
Commit d0a0bfe6729ef6044d76ea49fafa07e29fa598bd added checks for port
names, but didn't add a check to ensure port->name is non-NULL. This
results in a SIGSEGV when adding a port when one of the previously-added
ports didn't have the 'name' property set.

target-i386: Clean up misuse of qdev_init() in realize method
x86_cpu_apic_realize() calls qdev_init() to realize the APIC.
qdev_init()'s error handling has unwanted side effects: it unparents
the device, and it calls qerror_report_err().
qerror_report_err() is always inappropriate in realize methods,
because it doesn't return the Error object. It either reports the
error to stderr or the human monitor, or it stores it in the QMP
monitor, where it makes the QMP command fail even though the realize
method succeeded.
Fortunately, qdev_init() can't actually fail here, because realize
can't fail for any of the three possible APIC device models.
Clean up by cutting out the qdev_init() middle-man: set property
"realized" directly.

block/raw-posix: fix launching with failed disks
Since commit c25f53b06eba1575d5d0e92a0132455c97825b83 ("raw: Probe
required direct I/O alignment") QEMU has failed to launch if image files
produce I/O errors.
Previously, QEMU would launch successfully and the guest would see the
errors when attempting I/O.
This is a regression and may prevent multipath I/O inside the guest,
where QEMU must launch and let the guest figure out by itself which
disks are online.
Tweak the alignment probing code in raw-posix.c to explicitly look for
EINVAL on Linux instead of bailing. The kernel refuses misaligned
requests with this error code and other error codes can be ignored.

Commit c53659f0 ("BlockConf: Call backend functions to detect geometry
and blocksizes") causes a segmentation fault on the invalid
configuration of a scsi device without a drive.
Let's check for conf.blk before calling blkconf_blocksizes. The error
will be handled later on in scsi_realize anyway.

block/vdi: Add locking for parallel requests
When allocating a new cluster, the first write to it must be the one
doing the allocation, because that one pads its write request to the
cluster size; if another write to that cluster is executed before it,
that write will be overwritten due to the padding.
See https://bugs.launchpad.net/qemu/+bug/1422307 for what can go wrong
without this patch.

iotests: Drop vpc from 004's and 104's format list
Both tests require the test image to have a specific size; this cannot
be guaranteed by vpc (unless tuning the test specifically for that
format).
It is safe to exclude vpc from 004 because what is tested there is
implemented in a generic part in the block layer and not
format-specific.
It is safe to exclude vpc from 104 because for vpc basically every image
size is "unaligned", so if that would break at some point in time, we
would quickly notice just by running the generic tests.

ahci: Recompute cur_cmd on migrate post load
When the AHCI HBA device is migrated, all of the information that
led to the request being created is stored in the AHCIDevice
structures, except for pointers into guest data where return
information needs to be stored.
The "cur_cmd" field is usually responsible for this.
To rebuild the cur_cmd pointer post-migration, we can utilize
the busy_slot index to figure out where the command header
we are still processing is.
This allows a machine in a halted state from rerror=stop or
werror=stop to be migrated and resume operations without issue.

ahci: add support for restarting non-queued commands
This is easy, since start_dma already restarts processing from the
beginning of the PRDT.
Migration is also easy to cover; the comment about busy_slot is
wrong, busy_slot will only be set if there is an error. In this
case we have nothing to do really. The core IDE code will restart
the operation and command list processing will proceed after the
erroring command has been completed.

ahci: Migrate IDEStatus
Amazingly, we weren't doing this before.
Make sure we migrate the IDEState structure that belongs to
the AHCIDevice.IDEBus structure during migrations.
No version numbering changes because AHCI is not officially
migratable (and we can all see with good reason why) so we
do not impact any official builds by altering the stream and
leaving it at version 1.
This fixes the rerror=stop/werror=stop test case where we wish
to migrate a halted job. Previously, the error code would not
migrate, so even if the job completed successfully, AHCI would
report an error because it would still have the placeholder
error code from initialization time.

ide: migrate initial request state via IDEBus
This only breaks backwards migration compatibility if the bus is in

two subsections (one for version 1, and one for version 2, but with
the same name) with different "_needed" callbacks. The v1 callback would
return true if error_status != 0 and the bus is PATA; the v2 callback
would return true if error_status != 0 and the bus is AHCI.
Forward migration keeps working.

BlockConf: Call backend functions to detect geometry and blocksizes
geometry: hd_geometry_guess function autodetects the drive geometry.
This patch adds a block backend call, that probes the backing device
geometry. If the inner driver method is implemented and succeeds
(currently only for DASDs), the blkconf_geometry will pass-through
the backing device geometry. Otherwise will fallback to old logic.
blocksize: This patch initializes blocksize properties to 0.
In order to set the property a blkconf_blocksizes was introduced.
If user didn't set physical or logical blocksize, it will
retrieve its value from a driver (only succeeds for DASD), otherwise
it will set default 512 value.
The blkconf_blocksizes call was added to all users of BlkConf.

block: Add driver methods to probe blocksizes and geometry
Introduce driver methods of defining disk blocksizes (physical and
logical) and hard drive geometry.
Methods are only implemented for "host_device". For "raw" devices
driver calls child's method.
For now geometry detection will only work for DASD devices. To check
that a local check_for_dasd function was introduced. It calls BIODASDINFO2
ioctl and returns its rc.
Blocksizes detection function will probe sizes for DASD devices.

blkdebug: fix "once" rule
Background:
The blkdebug scripts are currently engineered so that when a debug
event occurs, a prefilter browses a master list of parsed rules for a
certain event and adds them to an "active list" of rules to be used for
the forthcoming action, provided the events and state numbers match.
Then, once the request is received, the last active rule is used to
inject an error if certain parameters match.
This active list is cleared every time the prefilter injects a new
rule for the first time during a debug event.
The "once" rule currently causes the error injection, if it is
triggered, to only clear the active list. This is insufficient for
preventing future injections of the same rule.
Remedy:
This patch /deletes/ the rule from the list that the prefilter
browses, so it is gone for good. In V2, we remove only the rule of
interest from the active list instead of allowing the "once" rule to
clear the entire list of active rules.
Impact:
This affects iotests 026. Several ENOSPC tests that used "once" can
be seen to have output that shows multiple failure messages. After
this patch, the error messages tend to be smaller and less severe, but
the injection can still be seen to be working. I have patched the
expected output to expect the smaller error messages.

iotests: Prepare for refcount_bits option
Some tests do not work well with certain refcount widths (i.e. you
cannot create internal snapshots with refcount_bits=1), so make those
widths unsupported.
Furthermore, add another filter to _filter_img_create in common.filter
which filters out the refcount_bits value.
This is necessary for test 079, which does actually work with any
refcount width, but invoking qemu-img directly leads to the
refcount_bits value being visible in the output; use _make_test_img
instead which will filter it out.

qcow2: Helper function for refcount modification
Since refcounts do not always have to be a uint16_t, all refcount blocks
and arrays in memory should not have a specific type (thus they become
pointers to void) and for accessing them, two helper functions are used
(a getter and a setter). Those functions are called indirectly through
function pointers in the BDRVQcowState so they may later be exchanged
for different refcount orders.
With the check and repair functions using this function, the refcount
array they are creating will be in big endian byte order; additionally,
using realloc_refcount_array() makes the size of this refcount array
always cluster-aligned. Both combined allow rebuild_refcount_structure()
to drop the bounce buffer which was used to convert parts of the
refcount array to big endian byte order and store them on disk. Instead,
those parts can now be written directly.

qcow2: Helper for refcount array reallocation
Add a helper function for reallocating a refcount array, independent of
the refcount order. The newly allocated space is zeroed and the function
handles failed reallocations gracefully.
The helper function will always align the buffer size to a cluster
boundary; if storing the refcounts in such an array in big endian byte
order, this makes it possible to write parts of the array directly as
refcount blocks into the image file.

qcow2: Use unsigned addend for update_refcount()
update_refcount() and qcow2_update_cluster_refcount() currently take a
signed addend. At least one caller passes a value directly derived from
an absolute refcount that should be reached ("l2_refcount - 1" in
expand_zero_clusters_in_l1()). Therefore, the addend should be unsigned
as well; this will be especially important for 64 bit refcounts.
Because update_refcount() then no longer knows whether the refcount
should be increased or decreased, it now requires an additional flag
which specified exactly that. The same applies to
qcow2_update_cluster_refcount().

qcow2: Only return status from qcow2_get_refcount
Refcounts can theoretically be of type uint64_t; in order to be able to
represent the full range, qcow2_get_refcount() cannot use a single
variable to represent both all refcount values and also keep some values
reserved for errors.
One solution would be to add an Error pointer parameter to
qcow2_get_refcount(); however, no caller could (currently) pass that
error message, so it would have to be emitted immediately and be
passed to the next caller by returning -EIO or something similar.
Therefore, an Error parameter does not offer any advantages here.
The solution applied by this patch is simpler to use. Because no caller
would be able to pass the error message, they would have to print it and
free it, whereas with this patch the caller only needs to pass the
returned integer (which is often a no-op from the code perspective,
because that integer will be stored in a variable "ret" which will be
returned by the fail path of many callers).

vnc: -readconfig fix
Now that -vnc goes through QemuOpts we can get vnc configuration
via -readconfig too. So setting display_remote in the command
line parsing code doesn't cut it any more, we must check QemuOpts
instead to see whenever any vnc display is configured.

x86: fix SS selector in SYSRET
According to my reading of the Intel documentation, the SYSRET instruction
is supposed to force the RPL bits of the %ss register to 3 when returning
to user mode. The actual sequence is:
SS.Selector <-- (IA32_STAR[63:48]+8) OR 3; (* RPL forced to 3 *)
However, the code in helper_sysret() leaves them at 0 (in other words, the "OR
3" part of the above sequence is missing). It does set the privilege level
bits of %cs correctly though.
This has caused me trouble with some of my VxWorks development: code that runs
okay on real hardware will crash on QEMU, unless I apply the patch below.

scsi: Improve error reporting for invalid drive property
When setting "realized" fails, scsi_bus_legacy_add_drive() passes the
error to qerror_report_err(), then returns an unspecific "Setting
drive property failed" error, which is reported further up the call
chain.
Example:
$ qemu-system-x86_64 -nodefaults -S -display none \
> -drive if=scsi,id=foo,file=tmp.qcow2 -global isa-fdc.driveA=foo
qemu-system-x86_64: -drive if=scsi,id=foo,file=tmp.qcow2: Property 'scsi-disk.drive' can't take value 'foo', it's in use
qemu-system-x86_64: Setting drive property failed
qemu-system-x86_64: Initialization of device lsi53c895a failed: Device initialization failed
Clean up the obvious way: simply return the original error to the
caller. Gets rid of the second message in the above error cascade.

hw: Propagate errors through qdev_prop_set_drive()
Three kinds of callers:
1. On failure, report the error and abort
Passing &error_abort does the job. No functional change.
2. On failure, report the error and exit()
This is qdev_prop_set_drive_nofail(). Error reporting moves from
qdev_prop_set_drive() to its caller. Because hiding away the error
in the monitor right before exit() isn't helpful, replace
qerror_report_err() by error_report_err(). Shouldn't make a
difference, because qdev_prop_set_drive_nofail() should never be
used in QMP context.
3. On failure, report the error and recover
This is usb_msd_init() and scsi_bus_legacy_add_drive(). Error
reporting and freeing the error object moves from
qdev_prop_set_drive() to its callers.
Because usb_msd_init() can't run in QMP context, replace
qerror_report_err() by error_report_err() there.
No functional change.
scsi_bus_legacy_add_drive() calling qerror_report_err() is of
course inappropriate, but this commit merely makes it more obvious.
The next one will clean it up.

scsi: Clean up duplicated error in legacy if=scsi code
Commit a818a4b changed scsi_bus_legacy_handle_cmdline() to report
errors from scsi_bus_legacy_add_drive() with error_report() in
addition to returning them. That's inappropriate.
Two kinds of callers:
1. realize methods (devices "esp", "virtio-scsi-device" and
"spapr-vscsi")
The error object gets passed up the call chain until it gets
reported again and freed.
Example:
$ qemu-system-arm -M virt -S -display none \
> -drive if=scsi,id=foo,bus=1,file=tmp.qcow2 \
> -device nec-usb-xhci -device usb-storage,drive=foo \
> -device virtio-scsi-pci
qemu-system-arm: -drive if=scsi,id=foo,bus=1,file=tmp.qcow2: Property 'scsi-disk.drive' can't take value 'foo', it's in use
qemu-system-arm: -drive if=scsi,id=foo,bus=1,file=tmp.qcow2: Setting drive property failed
qemu-system-arm: -device virtio-scsi-pci: Setting drive property failed
qemu-system-arm: -device virtio-scsi-pci: Device initialization failed
qemu-system-arm: -device virtio-scsi-pci: Device 'virtio-scsi-pci' could not be initialized
The second message in this error cascade comes from
scsi_bus_legacy_handle_cmdline(). The error object then gets
passed up to the qdev_init() called from
virtio_scsi_pci_init_pci(), which reports it again.
2. init methods (devices "am53c974", "dc390", "lsi53c895a",
"lsi53c810", "megasas", "megasas-gen2")
init methods need to report their errors with qerror_report().
These don't. The inappropriate error_report() papers over the bug.
error_report() isn't the same as qerror_report() in QMP context,
but this can't actually happen: QMP can still only hot-plug, and
callers call scsi_bus_legacy_handle_cmdline() only on cold-plug.
Except for sysbus_esp_realize(), but that can't be hot-plugged at
all, as far as I can tell.
Fix the init methods and drop the inappropriate error_report() in
scsi_bus_legacy_handle_cmdline().

rcu: handle forks safely
After forking, only the calling thread is duplicated in the child process.
The call_rcu thread has to be recreated in the child. Exploit the fact
that only one thread exists (same as when constructors run), and just redo
the entire initialization to ensure the threads are in the proper state.
The only additional things to do are emptying the list of threads
registered with RCU, and unlocking the lock that was taken in the prepare
callback (implementations are allowed to fail pthread_mutex_init()
if the mutex is still locked).

qemu-thread: do not use PTHREAD_MUTEX_ERRORCHECK
PTHREAD_MUTEX_ERRORCHECK is completely broken with respect to fork.
The way to safely do fork is to bring all threads to a quiescent
state by acquiring locks (either in callers---as we do for the
iothread mutex---or using pthread_atfork's prepare callbacks)
and then release them in the child.
The problem is that releasing error-checking locks in the child
fails under glibc with EPERM, because the mutex stores a different
owner tid than the duplicated thread in the child process. We
could make it work for locks acquired via pthread_atfork, by
recreating the mutex in the child instead of unlocking it
(we know that there are no other threads that could have taken
the mutex; but when the lock is acquired in fork's caller
that would not be possible.
The simplest solution is just to forgo error checking.

Real sun4u systems memory-map the NVRAM on the (ISA) ebus, so switch over to
MMIO from ioport access whilst setting the base year to 1968 as used by Sun
systems. This allows all SPARC64 OSs included in my tests to correctly detect
the NVRAM IC and read the hardware clock correctly upon boot.
Note that this also requires a corresponding OpenBIOS update to r1330 in order
to switch the SPARC64 NVRAM accessors over from ioport to MMIO.

s390x/kvm: deliver SIGP RESTART directly if stopped
According to the PoP, a restart irq has to be delivered "without first honoring
any other pending interruptions", if a cpu is in the STOPPED state.
While it is hard to implement this case in kvm, it can easily be handled in qemu.

s390x/kvm: implement handling of new SIGP orders
This patch adds handling code for the following SIGP orders:
- SIGP SET ARCHITECTURE
- SIGP SET PREFIX
- SIGP STOP
- SIGP STOP AND STORE STATUS
- SIGP STORE STATUS AT ADDRESS
SIGP STOP (AND STORE STATUS) are the only orders that can stay pending forever
(and may only be interrupted by resets), so special care has to be taken about
them. Their status also has to be tracked within QEMU. This patch takes
care of migrating this status (e.g. if migration happens during a SIGP STOP).
Due to the BQL, only one VCPU is currently able to execute SIGP handlers at a
time. According to the PoP, BUSY should be returned if another SIGP order is
currently being executed on a VCPU. This can only be implemented when the BQL
does not protect all handlers. For now, all SIGP orders on all VCPUs will be
serialized, which will be okay for the first shot.

Whenever we set the SIGP status in the status register, we have to wipe out

always be set to STATUS_STORED.
Let's introduce the wrapper for SigpInfo, as this will avoid most duplicate
code in the future.

s390x/kvm: more details for SIGP handler with one destination vcpu
Whenever a sigp order is to be executed by a target vcpu, we use run_on_cpu().
As we have only one pointer to pass all data to these sigp handlers, let's
introduce the struct sigp_info and use it as a transport container.
All orders targeting a single vcpu are now dispatched from a separate
handler. The destination vcpu is only valid for these orders and must not be
checked for SIGP SET ARCHITECTURE.
The sigp_info is filled with life in this new handler and used to pass the
information about the sigp order to the existing handlers. The cc is set
within these handlers.
Rename sigp_cpu_start() and sigp_cpu_restart() on the way to match the SIGP
order names (in order to avoid touching affected lines several times).

Milkymist pfpu has no jump instructions, so checking for MICROCODE_WORDS

allowed one loop too many,

The code can still access out of bounds, because it presumes that PC register
always begins at 0, and we allow writing to it.

memsave: Improve and disambiguate error message
When requesting a size which cannot be read, the error message shows
a different address which is misleading to the user and it looks like
something's wrong with the address parsing. This is because the input
@addr variable is incremented in the memory dumping loop:
(qemu) memsave 0xffffffff8418069c 0xb00000 mem
Invalid addr 0xffffffff849ffe9c specified
Fix that by saving the original address and size and use them in the
error message:

Invalid addr 0xffffffff8418069c/size 11534336 specified

target-i386: Require APIC ID to be explicitly set before CPU realize
On softmuu, instead of setting APIC ID automatically when creating a
X86CPU, require the property to be set before realizing the object
(which is already done by the CPU creation code on PC).
Keep apic_id = 0 by default on *-user so it can simply create a new CPU
object and realize it without extra steps (so target-i386 will be able
to use cpu_generic_init() eventually).

target-i386: Remove unused APIC ID default code
The existing apic_id = cpu_index code has no visible effect: the PC code
already initializes the APIC ID according to the topology on
pc_new_cpu(), and linux-user memcpy()s the CPU state (including
cpuid_apic_id) on cpu_copy().
Remove the dead code and simply let APIC ID to to be 0 by default. This
doesn't change behavior of PC because apic-id is already explicitly set,
and doesn't affect linux-user because APIC ID was already always 0.

sPAPR: Implement EEH RTAS calls
The emulation for EEH RTAS requests from guest isn't covered
by QEMU yet and the patch implements them.
The patch defines constants used by EEH RTAS calls and adds
callbacks sPAPRPHBClass::{eeh_set_option, eeh_get_state, eeh_reset,
eeh_configure}, which are going to be used as follows:
* RTAS calls are received in spapr_pci.c, sanity check is done
there.
* RTAS handlers handle what they can. If there is something it
cannot handle and the corresponding sPAPRPHBClass callback is
defined, it is called.
* Those callbacks are only implemented for VFIO now. They do ioctl()
to the IOMMU container fd to complete the calls. Error codes from
that ioctl() are transferred back to the guest.

target-ppc: Add versions to server CPU descriptions
5b79b1c "target-ppc: Create versionless CPU class per family if KVM" added
a dynamic CPU class registration with the name of the CPU family which
QEMU is running on. For example, this allowed specifying "-cpu POWER7"
on every version of POWER7 machine, not just the one which POWER7 was
an alias of. I.e. before 5b79b1c, "-cpu POWER7" would not work on real
POWER7 2.1 and would work on POWER7 2.3 only. The same story for POWER8.
However that patch broke POWER5+ support as POWER5+ CPU uses the same
name as the CPU class so dynamic registering of the POWER5+ class failed.
This redefines POWER5+ server CPUs by adding a version to them and adding
an alias for TCG case. KVM will use dynamically registered CPUs.
While we are here, do the same for 970 CPU.

PPC: Introduce the Virtual Time Base (VTB) SPR register
This patch adds basic support for the VTB.
PowerISA:
The Virtual Time Base (VTB) is a 64-bit incrementing counter.
Virtual Time Base increments at the same rate as the Time Base until its value
becomes 0xFFFF_FFFF_FFFF_FFFF (2 64 - 1); at the next increment its value
becomes 0x0000_0000_0000_0000. There is no interrupt or other indication when
this occurs.
The operation of the Virtual Time Base has the following additional
properties.
1. Loading a GPR from the Virtual Time Base has no effect on the accuracy of
the Virtual Time Base.
2. Copying the contents of a GPR to the Virtual Time Base replaces the
contents of the Virtual Time Base with the contents of the GPR.

vga: Expose framebuffer byteorder as a QOM property
The VGA device model now supports having the framebuffer in either endian,
and can be switched between these by the guest via a register in the qext
region.
However, in some cases (e.g. LE OS on the pseries machine) we have
existing guest that don't know about the endian switch register, but other
parts of the qemu code have better information to set a default endianness
than the VGA code does of itself.
In order to allow them to set a correct default endianness in these cases,
without breaking abstraction walls, this patch exposes the VGA framebuffer

pseries: Move rtc_offset into RTC device's state structure
The initial creation of the PAPR RTC qdev class left a wart - the rtc's
offset was left in the sPAPREnvironment structure, accessed via a global.
This patch moves it into the RTC device's own state structure, were it
belongs. This requires a small change to the migration stream format. In
order to handle incoming streams from older versions, we also need to
retain the rtc_offset field in the sPAPREnvironment structure, so that it
can be loaded into via the vmsd, then pushed into the RTC device.
Since we're changing the migration format, this also takes the opportunity
to:
* Change the rtc offset from a value in seconds to a value in
nanoseconds, allowing nanosecond offsets between host and guest
rtc time, if desired.
* Remove both the already unused "next_irq" field and now unused
"rtc_offset" field from the new version of the spapr migration
stream

pseries: Make the PAPR RTC a qdev device
At present the PAPR RTC isn't a "device" as such - it's accessed only via
firmware/hypervisor calls, and is handled in the sPAPR core code. This
becomes inconvenient as we extend it in various ways.
This patch makes the PAPR RTC a separate device in the qemu device model.
For now, the only piece of device state - the rtc_offset - is still kept in
the global sPAPREnvironment structure. That's clearly wrong, but leaving
it to be fixed in a following patch makes for a clearer separation between
the internal re-organization of the device, and the behavioural changes
(because the migration stream format needs to change slightly when the
offset is moved into the device's own state).

pseries: Make RTAS time of day functions respect -rtc options
In the 'pseries' machine the real time clock is provided by a
paravirtualized firmware interface rather than a device per se; the RTAS
get-time-of-day and set-time-of-day calls.
Out current implementations of those work directly off host time (with
an offset), not respecting options such as clock=vm which can be
specified in the -rtc command line option.
This patch reworks the RTAS RTC code to respect those options, primarily
by basing them on the qemu_clock_get_ns(rtc_clock) function instead of
directly on qemu_get_timedate() (which essentially handles host time, not
virtual rtc time).
As a bonus, this means our get-time-of-day function now also returns
nanoseconds.

spapr-pci: Enable huge BARs
At the moment sPAPR only supports 512MB window for MMIO BARs. However
modern devices might want bigger 64bit BARs.
This extends MMIO window from 512MB to 62GB (aligned to
SPAPR_PCI_WINDOW_SPACING) and advertises it in 2 records in
the PHB "ranges" property. 32bit gets the space from
SPAPR_PCI_MEM_WIN_BUS_OFFSET till the end of 4GB, 64bit gets the rest
of the space. If no space is left, 64bit range is not advertised.
The MMIO space size is set to old value of 0x20000000 by default
for pseries machines older than 2.3.
The approach changes the device tree which is a guest visible change, however
it won't break migration as:
1. we do not support migration to older QEMU versions
2. migration to newer QEMU will migrate the device tree as well and since
the new layout only extends the old one and does not change address mappigns,
no breakage is expected here too.
SLOF change is required to utilize this extension.

pseries: Limit PCI host bridge "index" value
pseries guests can have large numbers of PCI host bridges. To avoid the
user having to specify a number of different configuration values for every
one, the device supports an "index" property which is a shorthand setting
the various window and configuration addresses from a predefined sensible
set.
There are some problems with the details at present:
* The "index" propery is signed, but negative values will create PCI
windows below where we expect, potentially colliding with other devices
* No limit is imposed on the "index" property and large values can
translate to extremely large window addresses. With PCI passthrough in
particular this can mean we exceed various mapping and physical address
limits causing the guest host bridge to not work in strange ways.
This patch addresses this, by making "index" unsigned, and imposing a
limit. Currently the limit allows indices from 0..255 which is probably
enough host bridges for the time being. It's fairly easy to extend if
we discover we need more.

spapr_vio/spapr_iommu: Move VIO bypass where it belongs
Instead of tweaking a TCE table device by adding there a bypass flag,
let's add an alias to RAM and IOMMU memory region, and enable/disable
those according to the selected bypass mode.
This way IOMMU memory region can have size of the actual window rather
than ram_size which is essential for upcoming DDW support.
This moves bypass logic to VIO layer and keeps @bypass flag in TCE table
for migration compatibility only. This replaces spapr_tce_set_bypass()
calls with explicit assignment to avoid confusion as the function could
do something more that just syncing the @bypass flag.
This adds a pointer to VIO device into the sPAPRTCETable struct to provide
the sPAPRTCETable device a way to update bypass mode for the VIO device.

BDRVRawState *s = aiocb->bs->opaque;
This variable is used only when on of the following macros are defined
CONFIG_XFS, CONFIG_FALLOCATE, CONFIG_FALLOCATE_PUNCH_HOLE or
CONFIG_FALLOCATE_ZERO_RANGE. Fortunately, CONFIG_FALLOCATE_PUNCH_HOLE
and CONFIG_FALLOCATE_ZERO_RANGE could be defined only along with

sheepdog: selectable object size support
Previously, qemu block driver of sheepdog used hard-coded VDI object size.
This patch enables users to handle VDI object size.
When you start qemu, you don't need to specify additional command option.
But when you create the VDI which doesn't have default object size
with qemu-img command, you specify object_size option.
If you want to create a VDI of 8MB object size,
you need to specify following command option.
# qemu-img create -o object_size=8M sheepdog:test1 100M
In addition, when you don't specify qemu-img command option,
a default value of sheepdog cluster is used for creating VDI.
# qemu-img create sheepdog:test2 100M

vpc: Implement bdrv_co_get_block_status()
This implements bdrv_co_get_block_status() for VHD images. This can
significantly speed up qemu-img convert operation because only with this
function implemented sparseness can be considered. (Before, converting a
1 TB empty image took several minutes for me, now it's instantaneous.)

coroutine: Clean up qemu_coroutine_enter()
qemu_coroutine_enter() is now the only user of coroutine_swap(). Both
functions are short, so inline it.
Also, using COROUTINE_YIELD is now even more confusing because this code
is never called during qemu_coroutine_yield() any more. In fact, this
value is never read back, so we can just introduce a new COROUTINE_ENTER
which documents the purpose of the task switch better.

coroutine: Fix use after free with qemu_coroutine_yield()
Instead of using the same function for entering and exiting coroutines,
and hoping that it doesn't add any functionality that hurts with the
parameters used for exiting, we can just directly call into the real
task switch in qemu_coroutine_switch().
This fixes a use-after-free scenario where reentering a coroutine that
has yielded still accesses the old parent coroutine (which may have
meanwhile terminated) in the part of coroutine_swap() that follows
qemu_coroutine_switch().

virtio-balloon: Fix balloon not working correctly when hotplug memory
When do memory balloon, it takes the 'ram_size' as the VM's current ram size,
But 'ram_size' is the startup configured ram size, it does not take into
account the hotplugged memory.
As a result, the balloon result will be confused.
Steps to reproduce:
(1)Start VM: qemu -m size=1024,slots=4,maxmem=8G
(2)In VM: #free -m : 1024M
(3)qmp balloon 512M
(4)In VM: #free -m : 512M
(5)hotplug pc-dimm 1G
(6)In VM: #free -m : 1512M
(7)qmp balloon 256M
(8)In VM: #free -m :1256M
We expect the VM's available ram size to be 256M after 'qmp balloon 256M'
command, but VM's real available ram size is 1256M.
For "qmp balloon" is not performance critical code, we use function
'get_current_ram_size' to get VM's current ram size.

xhci: generate a Transfer Event for each Transfer TRB with the IOC bit set
At the moment, when the XHCI driver in edk2
(MdeModulePkg/Bus/Pci/XhciDxe/XhciDxe.inf) runs on QEMU, with the options

XhcSyncTrsRing() [Pci/XhciDxe/XhciSched.c]
ASSERT (TrsRing != NULL) [4]
UsbEnumerateNewDev() in the USB bus driver issues a GET_DESCRIPTOR
request, in order to determine the number of configurations that the
endpoint supports. The requests consists of three stages (three TRBs),
setup, data, and status. The length of the response is determined in [1],
namely from the transfer event that the host controller generates in
response to the request's middle stage (ie. the data stage).
If the length of the answer is correct (a full GET_DESCRIPTOR request
takes 18 bytes), then the XHCI driver that underlies the USB bus driver
"snoops" (caches) the descriptor data for later [2].
Later, the USB bus driver sends a SET_CONFIG request. The underlying XHCI
driver allocates a transfer ring for the endpoint, relying on the data
snooped and cached in step [2].
Finally, the USB keyboard driver submits an asynchronous interrupt
transfer to manage the keyboard. As part of this it asserts [4] that the
ring has been allocated in step [3].
And this ASSERT() fires. The root cause can be found in the way QEMU
handles the initial GET_DESCRIPTOR request.
Again, that request consists of three stages (TRBs, Transfer Request
Blocks), "setup", "data", and "status". The XhcCreateTransferTrb()
function sets the IOC ("Interrupt on Completion") flag in each of these
TRBs.
According to the XHCI specification, the host controller shall generate a
Transfer Event in response to *each* individual TRB of the request that
had the IOC flag set. This means that QEMU should queue three events:
setup, data, and status, for edk2's XHCI driver.
However, QEMU only generates two events:
- one for the setup (ie. 1st) stage,
- another for the status (ie. 3rd) stage.
No event is generated for the middle (ie. data) stage. The loop in QEMU's
xhci_xfer_report() function runs three times, but due to the "reported"
variable, only the first and the last TRBs elicit events, the middle (data
stage) results in no event queued.
As a consequence:
- When handling the GET_DESCRIPTOR request, XhcCheckUrbResult() in [1]
does not update the response length from zero.
- XhcControlTransfer() thinks that the response is invalid (it has zero
length payload instead of 18 bytes), hence [2] is not reached; the
device descriptor is not stashed for later, and the number of possible
configurations is left at zero.
- When handling the SET_CONFIG request, (NumConfigurations == 0) from
above prevents the allocation of the endpoint's transfer ring.
- When the keyboard driver tries to use the endpoint, the ASSERT() blows
up.
The solution is to correct the emulation in QEMU, and to generate a
transfer event whenever IOC is set in a TRB.
The patch replaces
!reported && (IOC || foo) == !reported && IOC ||
!reported && foo
with
IOC || (!reported && foo) == IOC ||
!reported && foo
which only changes how
reported && IOC
is handled. (Namely, it now generates an event.)
Tested with edk2 built for "qemu-system-aarch64 -M virt" (ie.
"ArmVirtualizationQemu.dsc", aka "AAVMF"), and guest Linux.

spice: fix invalid memory access to vga.vram
vga_common_init() doesn't allow more than 256 MiB vram size and silently
shrinks any larger value. qxl_dirty_surfaces() used the unshrinked size
via qxl->shadow_rom.surface0_area_size when accessing the memory, which
resulted in segfault.
Add a workaround for this case and an assert if it happens again.
We have to bump the vga memory limit too, because 256 MiB wouldn't have
allowed 8k (it requires more than 128 MiB).
1024 MiB doesn't work, but 512 MiB seems fine.

bootdevice: check boot order argument validation before vm running
Either 'once' option or 'order' option can take effect for -boot at
the same time, that is say initial startup processing can check only
one. And pc.c's set_boot_dev() fails when its boot order argument
is invalid. This patch provide a solution fix this problem:
1. If "once" is given, register reset handler to restore boot order.
2. Pass the normal boot order to machine creation. Should fail when
the normal boot order is invalid.
3. If "once" is given, set it with qemu_boot_set(). Fails when the
once boot order is invalid.
4. Start the machine.
5. On reset, the reset handler calls qemu_boot_set() to restore boot
order. Should never fail.

vfio-pci: Enable device request notification support
Linux v4.0-rc1 vfio-pci introduced a new virtual interrupt to allow
the kernel to request a device from the user. When signaled, QEMU
will by default attmempt to hot-unplug the device. This is a one-
shot attempt with the expectation that the kernel will continue to
poll for the device if it is not returned. Returning the device when
requested is the expected standard model of cooperative usage, but we
also add an option option to disable this feature. Initially this
opt-out is set as an experimental option because we really should
honor kernel requests for the device.

cpus: be more paranoid in avoiding deadlocks
For good measure, ensure that the following sequence:
thread 1 calls qemu_mutex_lock_iothread
thread 2 calls qemu_mutex_lock_iothread
VCPU thread are created
VCPU thread enters execution loop
results in the VCPU threads letting the other two threads run
and obeying iothread_requesting_mutex even if the VCPUs are
not halted. To do this, check iothread_requesting_mutex
before execution starts.

cpus: fix deadlock and segfault in qemu_mutex_lock_iothread
When two threads (other than the low-priority TCG VCPU thread)
are competing for the iothread lock, a deadlock can happen. This
is because iothread_requesting_mutex is set to false by the first
thread that gets the mutex, and then the VCPU thread might never
yield from the execution loop. If iothread_requesting_mutex is
changed from a bool to a counter, the deadlock is fixed.
However, there is another bug in qemu_mutex_lock_iothread that
can be triggered by the new call_rcu thread. The bug happens
if qemu_mutex_lock_iothread is called before the CPUs are
created. In that case, first_cpu is NULL and the caller
segfaults in qemu_mutex_lock_iothread. To fix this, just
do not do the kick if first_cpu is NULL.

virtio-scsi: Allocate op blocker reason before blocking
s->blocker is really only used in hw/scsi/virtio-scsi.c; the only places
where it is used in hw/scsi/virtio-scsi-dataplane.c is when it is
allocated and when it is freed. That does not make a whole lot of sense
(and is actually wrong because this leads to s->blocker potentially
being NULL when blk_op_block_all() is called in virtio-scsi.c), so move
the allocation and destruction of s->blocker to the device realization
and unrealization in virtio-scsi.c, respectively.
Case in point:
$ echo -e 'eject drv\nquit' | \
x86_64-softmmu/qemu-system-x86_64 \
-monitor stdio -machine accel=qtest -display none \
-object iothread,id=thr -device virtio-scsi-pci,iothread=thr \
-drive if=none,file=test.qcow2,format=qcow2,id=drv \
-device scsi-cd,drive=drv
Without this patch:
(qemu) eject drv
[1] 10102 done
10103 segmentation fault (core dumped)
With this patch:
(qemu) eject drv
Device 'drv' is busy: block device is in use by data plane
(qemu) quit

pci-hotplug-old: Has been dead for five major releases, bury
Commit 79ca616 (v1.6.0) accidentally disabled legacy x86-only HMP
commands pci_add, pci_del: it defined CONFIG_PCI_HOTPLUG only as make
variable, not as preprocessor macro, killing the code conditional on
defined(CONFIG_PCI_HOTPLUG_OLD).
In all this time, nobody reported the loss. I only noticed it when I
tried to test some error reporting change that forced me to touch this
old crap again.
Fun: git-log hw/pci/pci-hotplug-old.c shows our faith in the backward
compatibility god has been strong enough to sacrifice at its altar
about a dozen times, but not strong enough to even once verify the
legacy feature's still there, let alone works.
Remove the commands along with the code backing them.

Also it fixes wrong IO range in CRS if "iobase"

PS:
Testing with XP shows that current default "iobase"
used SMC device conflicts with floppy controller IO,
but it's topic for another patch and I'd leave it

balloon: call qdev_alias_all_properties for proxy dev in balloon class init
The idea is that all other virtio devices are calling this helper
to merge properties of the proxy device. This is the only difference
in between this helper and code in inside virtio_instance_init_common.
The patch should not cause any harm as property list in generic balloon
code is empty.
This also allows to avoid some dummy errors like fixed by this

Makefile: fix up parallel building under MSYS+MinGW
This patch enables parallel building of QEMU in MSYS+MinGW environment.
Currently an attempt to build QEMU in parallel fails on generation of
version.lo (and version.o too).
The cause of the failure is that when listing prerequisites "Makefile"
references "config-host.h" by absolute path in some rules and by relative
path in others. Make cannot figure out that these references points to the
same file which leads to the race: the generation of "version.*" which
requires "$(BUILD_DIR)/config-host.h" is launched in parallel with the
generation of "config-host.h" needed by other "Makefile" targets.
This patch removes "$(BUILD_DIR)/" prefix from corresponding prerequisite
of "version.*". There is no other prerequisites "$(BUILD_DIR)/config-host.h"
found.
Also note that not every version of MSYS is able to build QEMU in parallel,
see: "http://sourceforge.net/p/mingw/bugs/1950/". The suggested version is
1.0.17.

Create specific config option for "platform-bus"
Currently the "platform-bus" device is included for all softmmu builds.
This bridge is intended for use on any platforms that require dynamic
creation of sysbus devices. However, at present it is used only for the
PPC E500 target, with plans for the ARM "virt" target in the immediate
future.
To avoid a not-very-useful entry appearing in "qemu -device ?" output on
other targets, this patch makes a specific config option for platform-bus
and enables it (for now) only on ppc configurations which include E500
and on ARM (which always includes the "virt" target).

Add specific config options for PCI-E bridges
The i82801b11, ioh3420 and xio3130 PCI Express devices are currently
included in the build unconditionally.
While they could theoretically appear on any target platform with PCI-E,
they're pretty unlikely to appear on platforms that aren't Intel derived.
Therefore, to avoid presenting unlikely-to-be-relevant devices to the user,
add config options to enable these components, and enable them by default
only on x86 and arm platforms.
(Note that this patch does include these for aarch64, via its inclusion of
arm-softmmu.mak).

block: Forbid bdrv_set_aio_context outside BQL
Even if the caller has both the old and the new AioContext's, there can
be a deadlock, due to the leading bdrv_drain_all.
Suppose there are four io threads (A, B, A0, B0) with A and B owning a
BDS for each (bs_a, bs_b); Now A wants to move bs_a to iothread A0, and
B wants to move bs_b to B0, at the same time:
iothread A iothread B
--------------------------------------------------------------------------
aio_context_acquire(A0) /* OK */ aio_context_acquire(B0) /* OK */
bdrv_set_aio_context(bs_a, A0) bdrv_set_aio_context(bs_b, B0)
-> bdrv_drain_all() -> bdrv_drain_all()
-> acquire A /* OK */ -> acquire A /* blocked */
-> acquire B /* blocked */ -> acquire B
... ...
Deadlock happens because A is waiting for B, and B is waiting for A.

scsi: give device a parent before setting properties
This mimics what is done in qdev_device_add, and lets the device be
freed in case something goes wrong. Otherwise, object_unparent returns
immediately without freeing the device, which is on the other hand left
in the parent bus's list of children.
scsi_bus_legacy_handle_cmdline then returns an error, and the HBA is
destroyed as well with object_unparent. But the lingering device that
was not removed in scsi_bus_legacy_add_drive cannot be removed now either,
and bus_unparent gets stuck in an infinite loop trying to empty the list
of children.
The right fix of course would be to assert in bus_add_child that the
device already has a bus, and remove the "safety net" that adds the
drive to the QOM tree in device_set_realized. I am not yet sure whether
that would entail changing all callers to qdev_create (as well as
isa_create and usb_create and the corresponding _try_create versions).

qemu-img: Suppress unhelpful extra errors in convert, amend

To fix, propagate errors through qemu_opts_do_parse(). This lifts the
error reporting into callers. Drop it from img_convert() and
img_amend(), keep it in qemu_chr_parse_compat(), bdrv_img_create().
Since I'm touching qemu_opts_do_parse() anyway, write a function

pc: acpi-build: create memory hotplug IO region dynamically
it replaces a static complied in DSDT MMIO region
for memory hotplug with one created at runtime
leaving only truly static memory hotplug related
ASL bits in DSDT. And replaces template patching
of MEMORY_SLOTS_NUMBER value with ASL API created
named value.
Later it also would make easier to reuse current
ACPI memory hotplug on other targets.
Also later it would be possible to move remaining
memory hotplug ASL methods into build_ssdt() and
add all memory hotplug related AML into SSDT only
when memory hotplug is enabled, further reducing
ACPI tables blob if memory hotplug isn't used.

pc: acpi-build: create CPU hotplug IO region dynamically
it replaces a static complied in DSDT MMIO region
for CPU hotplug with one created at runtime
leaving only truly static CPU hotplug related ASL
bits in DSDT.
It also puts CPU_HOTPLUG_RESOURCE_DEVICE into
PCI0 scope and reserves resources from it,
preparing for dropping manual hole punching
in PCI0._CRS.
Later it also would make easier to reuse current
ACPI CPU hotplug on other targets.
Also later it would be possible to move remaining
CPU hotplug ASL methods into build_ssdt() and
add all CPU hotplug related AML into SSDT only
when CPU hotplug is enabled, further reducing
ACPI tables blob if CPU hotplug isn't used.
impl. detail:
Windows XP can't handle /BSODs/ OperationRegion
declaration in DSDT when variable from SSDT is used
for specifying its address/length and also when
Field declared in DSDT with OperationRegion from
SSDT if DSDT is being parsed before SSDT.
But it works just fine when referencing named
fields from another table. Hence OperationRegion
and Field declaration are moved to SSDT to make
XP based editions work.
PS:
Later Windows editions seem to be fine with above
conditions.

acpi: include PkgLength size only when requested
Named/Reserved{Field} definition uses PkgLength [1] encoding to specify
field length, however it doesn't include size of PkgLength field itself,
while other block objects that have explicit length of its body account
for PkgLength size while encoding it [2].
This special casing isn't mentioned in ACPI spec, but that's what 'iasl'
compiles NamedField to so add extra argument to build_prepend_pkg_length()
to allow it handle the case.

acpi: introduce AML composer aml_append()
Adds for dynamic AML creation, which will be used
for piecing ASL/AML primitives together and hiding
from user/caller details about how nested context
should be closed/packed leaving less space for
mistakes and necessity to know how AML should be
encoded, allowing user to concentrate on ASL
representation instead.
For example it will allow to create AML like this:
init_aml_allocator();
...
Aml *scope = aml_scope("PCI0")
Aml *dev = aml_device("PM")
aml_append(dev, aml_name_decl("_ADR", aml_int(addr)))
aml_append(scope, dev);
...

virtio: cull virtio_bus_set_vdev_features
The only user of this function was virtio-ccw, and it should use
virtio_set_features() like everybody else: We need to make sure
that bad features are masked out properly, which this function did
not do.

acpi-build: simplify rsdp management for legacy
For legacy machine types, rsdp is not in RAM, so we need a copy of rsdp
for fw cfg. We previously used g_array_free with false parameter,
but this seems to confuse people.
This also wastes a bit of memory as the buffer is unused for new
machine types.
Let's just use plain g_memdup, and free original memory together with
the array.

parameter.

acpi-build: fix ACPI RAM management
This fixes multiple issues around ACPI RAM management:
RSDP and linker RAM aren't currently marked dirty
on update, so they won't be migrated correctly.
Let's handle all tables in the same way: set correct size (assert if
too big), update, mark RAM dirty.
This also drops assert checking that table size didn't change: table
size is fundamentally dynamic and depends on hw configuration,
just set the correct size and use that (memory core asserts if size is
too large).
This also means we can drop tracking table size, memory core does this
for us now.

exec: round up size on MR resize
Block size must fundamentally be a multiple of target page size.
Aligning automatically removes need to worry about the alignment
from callers.
Note: the only caller of qemu_ram_resize (acpi) already happens to have
size padded to a power of 2, but we would like to drop the padding in
ACPI core, and don't want to expose target page size knowledge to ACPI.

RSDT offset can change across reboots and that makes
immutable RSDP, which is build at startup, point to
incorrect place in ACPI table blob. That results in
BIOS corrupting tables and guest OS failing to find

qdev: Don't exit when running into bad -global
-global lets you set a nice booby-trap for yourself:
$ qemu-system-x86_64 -nodefaults -S -display none -usb -monitor stdio -global usb-mouse.usb_version=l
QEMU 2.1.94 monitor - type 'help' for more information
(qemu) device_add usb-mouse
Parameter 'usb_version' expects an int64 value or range
$ echo $?
1
Not nice. Until commit 3196270 we even abort()ed.
The same error triggers if you manage to screw up a machine type's
compat_props. To demonstrate, change HW_COMPAT_2_1's entry to
.driver = "usb-mouse",\
.property = "usb_version",\
.value = "1", \
Then run
$ qemu-system-x86_64 -usb -M pc-i440fx-2.1 -device usb-mouse
upstream-qemu: -device usb-mouse: Parameter 'usb_version' expects an int64 value or range
$ echo $?
1
One of our creatively cruel error messages.
Since this is actually a coding error, we *should* abort() here.
Replace the error by an assertion failure in this case.
But turn the fatal error into a mere warning when the faulty
GlobalProperty comes from the user. Looks like this:
$ qemu-system-x86_64 -nodefaults -S -display none -usb -monitor stdio -global usb-mouse.usb_version=l
QEMU 2.1.94 monitor - type 'help' for more information
(qemu) device_add usb-mouse
Warning: global usb-mouse.usb_version=l ignored (Parameter 'usb_version' expects an int64 value or range)
(qemu)
This is consistent with how we handle similarly unusable -global in
qdev_prop_check_globals().
You could argue that the error should make device_add fail. Would be
harder, because we're running within TypeInfo's instance_post_init()
method device_post_init(), which can't fail.

pci: Permit incremental conversion of device models to realize
Call the new PCIDeviceClass method realize(). Default it to
pci_default_realize(), which calls old method init().
To convert a device model, make it implement realize() rather than

pci: Convert core to realize
Implement DeviceClass methods realize() and unrealize() instead of
init() and exit(). The core's initialization errors now get
propagated properly, and QMP sends them instead of an unspecific
"Device initialization failed" error. Unrealize can't fail, so no
change there.
PCIDeviceClass is unchanged: it still provides init() and exit().
Therefore, device models' errors are still not propagated.

1. guest reIPL changes (Fan Zhang)
Implements subcode 5 and 6 of diag 0x308. This allows to use
/sys/firmware/[re]ipl/ccw/* and the chreipl and lsreipl tools in
Linux. In addition to the normal "change the disk" this also
allows to switch from booting an external kernel into rebooting
from a disk.
2. Memory page table walking (Thomas Huth)
Fix several page table walking functions, used in several places
like gdb server and instruction handling. Also use these functions
in several I/O related functions.

target-i386: Set APIC ID using cpu_index on CONFIG_USER
The PC CPU initialization code already sets apic-id based on the CPU
topology, and CONFIG_USER doesn't need the topology-based APIC ID
calculation code.
Make CONFIG_USER set apic-id before realizing the CPU (just like PC
already does), so we can simplify x86_cpu_initfn later. As there is no
CPU topology configuration in CONFIG_USER, just use cpu_index as the
APIC ID.

numa: Rename set_numa_modes() to numa_post_machine_init()
This function does some initialization that needs to be done after

CPUState.numa_node initialization to the CPU init code, but while the
function exists, lets give it a name that makes sense.

qapi-types: add C99 index names to arrays
It's not easy to figure out how monitor translates
strings: most QEMU code deals with translated indexes,
these are translated using _lookup arrays,
so you need to find the array name, and find the
appropriate offset.
This patch adds C99 indexes to lookup arrays, which makes it possible to
find the correct key using simple grep, and see that the matching is
correct at a glance.
Example:
Before:
const char *MigrationCapability_lookup[] = {
"xbzrle",
"rdma-pin-all",
"auto-converge",
"zero-blocks",
NULL,
};
After:
const char *MigrationCapability_lookup[] = {
[MIGRATION_CAPABILITY_XBZRLE] = "xbzrle",
[MIGRATION_CAPABILITY_RDMA_PIN_ALL] = "rdma-pin-all",
[MIGRATION_CAPABILITY_AUTO_CONVERGE] = "auto-converge",
[MIGRATION_CAPABILITY_ZERO_BLOCKS] = "zero-blocks",
[MIGRATION_CAPABILITY_MAX] = NULL,
};

hmp: Name HMP command handler functions hmp_COMMAND()
Some are called do_COMMAND() (old ones, usually), some hmp_COMMAND(),
and sometimes COMMAND pointlessly differs in spelling.
Normalize to hmp_COMMAND(), where COMMAND is exactly the command name
with '-' replaced by '_'.
Exceptions:
* do_device_add() and client_migrate_info() *not* renamed to
hmp_device_add(), hmp_client_migrate_info(), because they're also
QMP handlers. They still need to be converted to QAPI.
* do_memory_dump(), do_physical_memory_dump(), do_ioport_read(),
do_ioport_write() renamed do hmp_* instead of hmp_x(), hmp_xp(),
hmp_i(), hmp_o(), because those names are too cryptic for my taste.
* do_info_help() renamed to hmp_info_help() instead of hmp_info(),
because it only covers help.

Make sysbus EHCI devices ARM only by default
A number of ARM embedded boards include EHCI USB host controllers which
appear as directly mapped devices, rather than sitting on a PCI bus.
At present code to emulate such devices is included whenever EHCI support
is included. This patch adjusts teh config options to only include them
in builds targetting ARM by default.

usb: Suppress bogus error when automatic usb-hub creation fails
USBDevice's realize method usb_qdev_realize() automatically creates a
usb-hub when only one port is left. Creating devices in realize
methods is questionable, but works.
If usb-hub creation fails, an error is reported to stderr, but the
failure is otherwise ignored. We then create the actual device using
the last port, which may well succeed.
Example:
$ qemu -nodefaults -S -display none -machine usb=on -monitor stdio
QEMU 2.2.50 monitor - type 'help' for more information
(qemu) device_add usb-mouse
[Repeat 36 times]
(qemu) info usb
Device 0.0, Port 1, Speed 12 Mb/s, Product QEMU USB Mouse
Device 0.0, Port 2, Speed 12 Mb/s, Product QEMU USB Hub
Device 0.0, Port 2.1, Speed 12 Mb/s, Product QEMU USB Mouse
[More mice and hubs omitted...]
Device 0.0, Port 2.8.8.8.8.7, Speed 12 Mb/s, Product QEMU USB Mouse
(qemu) device_add usb-mouse
usb hub chain too deep
Failed to initialize USB device 'usb-hub'
(qemu) info usb
[...]
Device 0.0, Port 2.8.8.8.8.7, Speed 12 Mb/s, Product QEMU USB Mouse
Device 0.0, Port 2.8.8.8.8.8, Speed 12 Mb/s, Product QEMU USB Mouse
Despite the "Failed" message, the command actually succeeded.
In QMP, it's worse. When adding the 37th mouse via QMP, the command
fails with
{"error": {"class": "GenericError", "desc": "usb hub chain too deep"}}
Additionally, "Failed to initialize USB device 'usb-hub'" is reported
on stderr. Despite the command failure, the device was created. This
is wrong.
Fix by avoiding qdev_init() for usb-hub creation, so we can ignore
errors cleanly.

usb: Improve -usbdevice error reporting a bit
Most LegacyUSBFactory usbdevice_init() methods realize with
qdev_init_nofail(), even though their caller usbdevice_create() can
handle failure. Okay if it really can't fail (I didn't check), but
somewhat brittle.
usb_msd_init() and usb_bt_init() call qdev_init(). The latter
additionally reports an error when qdev_init() fails.
Realization failure produces multiple error reports: a specific one
from qdev_init(), and generic ones from usb_bt_init(),
usb_create_simple(), usbdevice_create() and usb_parse().
Remove realization from the usbdevice_init() methods. Realize in
usbdevice_create(), and produce exactly one error message there. You
still get another one from usb_parse().

monitor: Clean up around monitor_handle_fd_param()
monitor_handle_fd_param() is a wrapper around
monitor_handle_fd_param2() that feeds errors to qerror_report_err()
instead of returning them. qerror_report_err() is inappropriate in
many contexts. monitor_handle_fd_param() looks simpler than
monitor_handle_fd_param2(), which tempts use. Remove the temptation:
drop the wrapper and open-code the (trivial) error handling instead.
Replace the open-coded qerror_report_err() by error_report_err() in
places that already use error_report(). Turns out that's everywhere.
While there, rename monitor_handle_fd_param2() to monitor_fd_param().

vhost-scsi: Improve error reporting for invalid vhostfd
We get two error messages: one from monitor_handle_fd_param2(), and
another one from vhost_scsi_realize(). The second one gets suppressed
in QMP context.
That's because monitor_handle_fd_param() calls qerror_report_err().
Calling qerror_report_err() is always inappropriate in realize
methods, because it doesn't return the Error object. It either
reports the error to stderr or the human monitor, or it stores it in
the QMP monitor, where it makes the QMP command fail even when the
realize method ignores the error and succeeds. Fortunately,
vhost_scsi_realize() doesn't do that.
Fix by switching to monitor_handle_fd_param2().

s390x/kvm: Add function for injecting pgm access exceptions
Program access exceptions are defined to deliver a translation exception
code in the low-core. Add a function trigger_access_exception() that
generates the proper program interrupt on both KVM and non-KVM systems
and switch the existing code to use it.

s390x/mmu: Renaming related to the ASCE confusion
An Address Space Control Element (ASCE) is only the very first unit of
an s390 address translation (normally residing in one of the control
registers). The entries in the page tables are called differently.
So let's call the relevant variable pt_entry instead of asce in
mmu_translate_pte() to avoid future confusion (thus there is no
functional change in this patch, just renaming).

s390x/mmu: Skip exceptions properly when translating addresses for debug
When a fault occurs during the MMU lookup in s390_cpu_get_phys_page_debug(),
the trigger_page_fault() function writes the translation exception code
into the lowcore - something you would not expect during a memory access
by the debugger. Ease this problem by adding an additional parameter to
mmu_translate() which can be used to specify whether a program check and
the translation exception code should be injected or not.

s390x/mmu: Fix the handling of the table levels
The current code used a wrong and very confusing way of dealing with
the table levels by introducing a "fake level above current". However,
the real problem was simply that the checks for the region/segment
invalid bit and for the matching region/segment level was done at the
wrong spot in the code - it has to be done after the first table entry
has been looked up instead (e.g. there is also no "invalid" bit in the
ASCE itself and the current "level" has to be the same as the level in
the entry that we just looked up).
Also the entries for the segment table are quite a bit different compared
to the region table entries. So this patch moves the related code into the
function mmu_translate_segment() to make it clear at which table level we
currently are and to get rid of the ugly switch-statement in the function
mmu_translate_region().

strtok_r is used only once in the code and we could simply rewrite
the code without it.

qga: add guest-set-user-password command
Add a new 'guest-set-user-password' command for changing the password
of guest OS user accounts. This command is needed to enable OpenStack
to support its API for changing the admin password of guests running
on KVM/QEMU. It is not practical to provide a command at the QEMU
level explicitly targetting administrator account password change
only, since different guest OS have different names for the admin
account. While UNIX systems use 'root', Windows systems typically
use 'Administrator' and even that can be renamed. Higher level apps
like OpenStack have the ability to figure out the correct admin
account name since they have info that QEMU/libvirt do not.
The command accepts either the clear text password string, encoded
in base64 to make it 8-bit safe in JSON:
$ echo -n "123456" | base64
MTIzNDU2
$ virsh -c qemu:///system qemu-agent-command f21x86_64 \
'{ "execute": "guest-set-user-password",
"arguments": { "crypted": false,
"username": "root",
"password": "MTIzNDU2" } }'
{"return":{}}
Or a password that has already been run though a crypt(3) like
algorithm appropriate for the guest, again then base64 encoded:
$ echo -n '$6$n01A2Tau$e...snip...DfMOP7of9AJ1I8q0' | base64
JDYkb...snip...YT2Ey
$ virsh -c qemu:///system qemu-agent-command f21x86_64 \
'{ "execute": "guest-set-user-password",
"arguments": { "crypted": true,
"username": "root",
"password": "JDYkb...snip...YT2Ey" } }'
NB windows support is desirable, but not implemented in this
patch.

Convert ram_list to RCU
Allow "unlocked" reads of the ram_list by using an RCU-enabled QLIST.
The ramlist mutex is kept. call_rcu callbacks are run with the iothread
lock taken, but that may change in the future. Writers still take the
ramlist mutex, but they no longer need to assume that the iothread lock
is taken.
Readers of the list, instead, no longer require either the iothread
or ramlist mutex, but they need to use rcu_read_lock() and
rcu_read_unlock().
One place in arch_init.c was downgrading from write side to read side
like this:
qemu_mutex_lock_iothread()
qemu_mutex_lock_ramlist()
...
qemu_mutex_unlock_iothread()
...
qemu_mutex_unlock_ramlist()
and the equivalent idiom is:
qemu_mutex_lock_ramlist()
rcu_read_lock()
...
qemu_mutex_unlock_ramlist()
...
rcu_read_unlock()

This for now is a simple TLB flush. This can change later for two
reasons:
1) an AddressSpaceDispatch will be cached in the CPUState object
2) it will not be possible to do tlb_flush once the TCG-generated code
runs outside the BQL.

pcie: remove mmconfig memory leak and wrap mmconfig update with transaction
This memory leak was introduced inadvertently by omitting object_unparent.
A better fix is to use the new memory_region_set_size instead of destroying
and recreating the MMIO region on the fly.
Also, ensure that unmapping and remapping the region is done atomically.

qemu-io: Use BlockBackend
qemu-io should behave like a guest, therefore it should use BlockBackend
to access the block layer.
There are a couple of places where that is infeasible: First, the
bdrv_debug_* functions could theoretically be mirrored in the
BlockBackend, but since these are functions internal to the block layer,
they should not be visible externally (qemu-io as a test tool is exempt
from this).
Second, bdrv_get_info() and bdrv_get_specific_info() work on a single
BDS alone, therefore they should stay BDS-specific.
Third, bdrv_is_allocated() mainly works on a single BDS as well. Some
data may be passed through from the BDS's file (if sectors which are
apparently allocated in the file are not really allocated there but just
zero).
[Fixed conflicts around block_acct_start() usage from Fam Zheng's
"qemu-io: Account IO by aio_read and aio_write" commit. Use
BlockBackend and blk_get_stats() instead of BlockDriverState.

qemu-io: Remove "growable" option
Remove "growable" option from the "open" command and from the qemu-io
command line. qemu-io is about to be converted to BlockBackend which
will make sure that no request exceeds the image size, so the only way
to keep "growable" would be to use BlockBackend if it is not given and
to directly access the BDS if it is.
qemu-io is a debugging tool, therefore removing a rarely used option
will have only a very small impact, if any. There was only one
qemu-iotest which used the option; since it is not critical, this patch
just removes it.

block: Add blk_new_open()
blk_new_with_bs() creates a BlockBackend with an empty BlockDriverState
attached to it. Empty BDSs are not nice, therefore add an alternative
function which combines blk_new_with_bs() with bdrv_open().
Note: In contrast to bdrv_open() which takes a BlockDriver parameter,
blk_new_open() does not take such a parameter. This is because
bdrv_open() opens a BlockDriverState, therefore it is natural to be able
to set the BlockDriver for that BDS. The fact that bdrv_open() can open
more than a single BDS is merely some form of a byproduct.
blk_new_open() on the other hand is intended to be used to create a
whole tree of BlockDriverStates. Therefore, setting a single BlockDriver
does not make much sense. Instead, the drivers to be used for each of
the nodes must be configured through the "options" QDict; including the
driver of the root BDS.

qemu-iotests: Add 093 for IO throttling
This case utilizes qemu-io command "aio_{read,write} -q" to verify the
effectiveness of IO throttling options.
It's implemented by driving the vm timer from qtest protocol, so the
throttling timers are signaled with determinied time duration. Then we
verify the completed IO requests are within 10% error of bps and iops
limits.
"null" protocol is used as the disk backend so that no actual disk IO is
performed on host, this will make the blockstats much more
deterministic. Both "null-aio" and "null-co" are covered, which is also
a simple cross validation test for the driver code.

Currently, the qemu_clock_deadline_ns_all (a few lines above) counts all

We find the nbd_recv_coroutines_enter_all function (triggered by a cancel
command or a network connection breaking down) will enter a coroutine which
is waiting for the sending lock. If the lock is still held by another coroutine,
the entering coroutine will be added into the co_queue again. Latter, when the
lock is released, a coroutine re-enter error will occur.
This bug can be fixed simply by delaying the setting of recv_coroutine as
suggested by paolo. After applying this patch, we have tested the cancel
operation in mirror phase looply for more than 5 hous and everything is fine.
Without this patch, a coroutine re-enter error will occur in 5 minutes.

qtest/ahci: Assert sector size in identify test
A minor sanity check to assert that the sector size is 512.
The current block layer code deeply assumes that the IDE

This is useful for the DMA tests, which currently assume that

libqos/ahci: add ahci_io
ahci_io is a wrapper around ahci_guest_io that takes a pointer to host
memory instead, and will create a guest memory buffer and copy the data
to/from as needed and as appropriate for a read/write command, such that
after a read, the guest data will be in a host buffer, and for a write,
the data will be transmitted to guest memory prior to the block operation.
Now that we have all the syntactic sugar functions in place for AHCI,
we can convert the identify test to be very, very short.

operate on the structure.
ahci_command_create - Initialize and create a new AHCICommand in memory
ahci_command_free - Destroy this object.
ahci_command_set_buffer - Set where the guest memory DMA buffer is.
ahci_command_commit - Write this command to the AHCI HBA.
ahci_command_issue - Issue the committed command synchronously.
ahci_command_issue_async - Issue the committed command asynchronously.
ahci_command_wait - Wait for an asynchronous command to finish.
ahci_command_slot - Get the number of the command slot we committed to.

To support the PIO sanity check, a new structure is added for the

members renamed slightly to condense reserved members into fewer
fields; and LBA fields are now represented by arrays of 8 byte chunks
instead of independent variables.

libqos/ahci: Add command header helpers
Adds command header helper functions:
-ahci_command_header_set
-ahci_command_header_get,
-ahci_command_destroy, and
-ahci_cmd_pick
These helpers help to quickly manage the command header information in
the AHCI device.
ahci_command_header_set and get will store or retrieve an AHCI command
header, respectively.
ahci_cmd_pick chooses the first available but least recently used
command slot to allow us to cycle through the available command slots.
ahci_command_destroy obliterates all information contained within a
given slot's command header, and frees its associated command table,
but not its DMA buffer!
Lastly, the command table pointer fields (dba and dbau) are merged into
a single 64bit value to make managing 64bit tests simpler.

dataplane: endianness-aware accesses
The vring.c code currently assumes that guest and host endianness match,
which is not true for a number of cases:
- emulating targets with a different endianness than the host
- bi-endian targets, where the correct endianness depends on the virtio
device
- upcoming support for the virtio-1 standard mandates little-endian
accesses even for big-endian targets and hosts
Make sure to use accessors that depend on the virtio device.
Note that dataplane now needs to be built per-target.

libqos/ahci: Functional register helpers
Introduce a set of "static inline" register helpers that are intended to
replace the current set of macros with more functional versions that are
better suited to inclusion in libqos than porcelain macros.
As a stopgap measure before eliminating the porcelain macros, define them
to use the new functions defined in the ahci.h header.

qtest/ahci: Store hba_base in AHCIQState
Store the HBA memory base address in the new state object, to simplify
function prototypes and encourage a more functional testing style.
This causes a lot of churn, but this patch is as "simplified" as I could
get it to be. This patch is therefore fairly mechanical and straightforward:
Any case where we pass "hba_base" has been consolidated into the AHCIQState
object and we pass the one unified parameter.
Any case where we reference "ahci" and "hba_state" have been modified to use
"ahci->dev" for the PCIDevice and "ahci->hba_state" to get at the base memory
address, accordingly.
Notes:
- A needless return is removed from start_ahci_device.
- For ease of reviewing, this patch can be reproduced (mostly) by:
# Replace (ahci, hba_base) prototypes with unified parameter
's/(QPCIDevice \*ahci, void \*\?\*hba_base/(AHCIQState *ahci/'
# Replace (ahci->dev, hba_base) calls with unified parameter
's/(ahci->dev, &\?hba_base)/(ahci)/'
# Replace calls to PCI config space using "ahci" with "ahci->dev"
's/qpci_config_\(read\|write\)\(.\)(ahci,/qpci_config_\1\2(ahci->dev,/'
After these, the remaining differences are easy to review by hand.

libqos: Update QGuestAllocator to be opaque
To avoid the architecture-specific implementations of the generic qtest
allocator having to know about fields within the allocator, add a
page_size setter method for users or arch specializations to use.
The allocator will assume a default page_size for general use, but it
can always be overridden.
Since this was the last instance of code directly using properties of the
QGuestAllocator object directly, modify the type to be opaque and move
the structure inside of malloc.c.
mlist_new, which was previously exported, is made static local to malloc.c,
as it has no external users.
[Peter Maydell <peter.maydell@linaro.org> reported the following clang
warning:

libqos: create libqos.c
The intent of this file is to serve as a misc. utilities file to be
shared amongst tests that are utilizing libqos facilities.
In a later patch, migration test helpers will be added to libqos.c that
will allow simplified testing of migration cases where libqos is
"Just Enough OS" for migrations testing.
The addition of the AHCIQState structure will also allow us to eliminate
global variables inside of qtests to manage allocators and test instances
in a better, more functional way.
libqos.c:
- Add qtest_boot
- Add qtest_shutdown
libqos.h:
- Create QOSState structure for allocator and QTestState.
ahci-test.c:
- Move qtest_boot and qtest_shutdown to libqos.c/h
- Create AHCIQState to interface with new qtest_boot/shutdown prototypes
- Modify tests slightly to use new types.
For now, the new object file is only linked to ahci-test, because it still
relies on pc architecture specific code in libqos. The next two patches will
reorganize the code to be more general.

guest. This could be an external kernel or a disk.

target-arm: A64: Fix handling of rotate in logic_imm_decode_wmask
The code in logic_imm_decode_wmask attempts to rotate a mask
value within the bottom 'e' bits of the value with
mask = (mask >> r) | (mask << (e - r));
This has two issues:
* if the element size is 64 then a rotate by zero results
in a shift left by 64, which is undefined behaviour
* if the element size is smaller than 64 then this will
leave junk in the value at bit 'e' and above, which is
not valid input to bitfield_replicate(). As it happens,
the bits at bit 'e' to '2e - r' are exactly the ones
which bitfield_replicate is going to copy in there,
so this isn't a "wrong code generated" bug, but it's
confusing and if we ever put an assert in
bitfield_replicate it would fire on valid guest code.
Fix the former by not doing anything if r is zero, and
the latter by masking with bitmask64(e).

pci: Add generic PCIe host bridge
With simple exposure of MMFG, ioport window, mmio window and an IRQ line we
can successfully create a workable PCIe host bridge that can be mapped anywhere
and only needs to get described to the OS using whatever means it likes.
This patch implements such a "generic" host bridge. It handles 4 legacy IRQ
lines. MSIs need to be handled external to the host bridge.
This device is particularly useful for the "pci-host-ecam-generic" driver in
Linux.

At present, we assume that the first tpg can boot only, and add
a boot_tpgt property that defaults to 0. Of course, people can
pass a valid value by qemu command line.

"channel@channel/vhost-scsi@target,lun".

qdev: support to get a device firmware path directly
commit 6b1566c (qdev: Introduce FWPathProvider interface) did a
good job for supproting to get firmware path on some different
architectures.
Moreover further more, we can use the interface to get firmware
path name for a device which isn't attached a specific bus,
such as virtio-bus, scsi-bus etc.
When the device (such as vhost-scsi) realize the TYPE_FW_PATH_PROVIDER
interface, we should introduce a new function to get the correct firmware
path name for it.

kvm_stat: Add kvm_exit reasons for aarch64
This patch defines the list of kvm_exit reasons for aarch64. This list is
based on the Exception Class (EC) field of HSR register. With this patch
users can trace the execution of guest VMs better. A sample output from
command "kvm_stat -1 -t" is shown as the following:
<...>
kvm_exit(WATCHPT_HYP) 0 0
kvm_exit(WFI) 9422 9361
NOTE: This patch requires TRACE_EVENT(kvm_exit) to include exit_reason
field in TP_ARGS. A patch to upstream kernel has been submitted.

vfio: Use vfio type1 v2 IOMMU interface
The difference between v1 and v2 is fairly subtle, simply more
deterministic behavior for unmaps. The v1 interface allows the user
to attempt to unmap sub-regions of previous mappings, returning
success with zero size if unable to comply. This was a reflection of
the underlying IOMMU API. The v2 interface requires that the user
may only unmap fully contained mappings, ie. an unmap cannot intersect
or bisect a previous mapping, but may cover multiple mappings. QEMU
never made use of the sub-region v1 support anyway, so we can support
either v1 or v2. We'll favor v2 since it's newer.

vfio: unmap and free BAR data in instance_finalize
In the case of VFIO, the unrealize callback is too early to munmap the
BARs. The munmap must be delayed until memory accesses are complete.
To do this, split vfio_unmap_bars in two. The removal step, now called
vfio_unregister_bars, remains in vfio_exitfn. The reclamation step
is vfio_unmap_bars and is moved to the instance_finalize callback.
Similarly, quirk MemoryRegions have to be removed during
vfio_unregister_bars, but freeing the data structure must be delayed
to vfio_unmap_bars.

vfio: free dynamically-allocated data in instance_finalize
In order to enable out-of-BQL address space lookup, destruction of
devices needs to be split in two phases.
Unrealize is the first phase; once it complete no new accesses will
be started, but there may still be pending memory accesses can still
be completed.
The second part is freeing the device, which only happens once all memory
accesses are complete. At this point the reference count has dropped to
zero, an RCU grace period must have completed (because the RCU-protected
FlatViews hold a reference to the device via memory_region_ref). This is
when instance_finalize is called.
Freeing data belongs in an instance_finalize callback, because the
dynamically allocated memory can still be used after unrealize by the
pending memory accesses.
This starts the process by creating an instance_finalize callback and
freeing most of the dynamically-allocated data in instance_finalize.
Because instance_finalize is also called on error paths or also when
the device is actually not realized, the common code needs some changes
to be ready for this. The error path in vfio_initfn can be simplified too.

vfio: cleanup vfio_get_device error path, remove vfio_populate_device callback
Now that vfio_put_base_device is called unconditionally at instance_finalize
time, it can be called twice if vfio_populate_device fails. This works
but it is slightly harder to follow.
Change vfio_get_device to not touch the vbasedev struct until it will
definitely succeed, moving the vfio_populate_device call back to vfio-pci.
This way, vfio_put_base_device will only be called once.

memory: unregister AddressSpace MemoryListener within BQL
address_space_destroy_dispatch is called from an RCU callback and hence
outside the iothread mutex (BQL). However, after address_space_destroy
no new accesses can hit the destroyed AddressSpace so it is not necessary
to observe changes to the memory map. Move the memory_listener_unregister
call earlier, to make it thread-safe again.

util/uri: URI member path can be null, compare more carfully
uri_resolve_relative() calls strcmp(bas->path, ref->path). However,
either argument could be null! Evidence: the code checks for null
after the comparison. Spotted by Coverity.
I suspect this was screwed up when we stole the code from libxml2.
There the conditional reads
xmlStrEqual((xmlChar *)bas->path, (xmlChar *)ref->path)
with
int
xmlStrEqual(const xmlChar *str1, const xmlChar *str2) {
if (str1 == str2) return(1);
if (str1 == NULL) return(0);
if (str2 == NULL) return(0);
do {
if (*str1++ != *str2) return(0);
} while (*str2++);
return(1);
}
Fix by replicating libxml2's logic faithfully.

When failure occurs during locking of vec[i], we also need to unlock all

Code in unlock_user() checks vec[i].iov_base for NULL, so there's no

If error is EFAULT when "i == 0", vec[i].iov_base is NULL, we can just
skip it, so can still use "while (--i >= 0)" loop condition.

vl: Fix bogus error message for implied mon ID clashing
monitor_parse() desugars --monitor, --qmp and -qmp-pretty to --mon.
The ID it picks can clash with a user-specified ID. When it happens,
the error message is misleading.
Reproducer:
$ qemu --mon id=compat_monitor0 --monitor stdio
Message before the patch:
duplicate chardev: compat_monitor0
There's no "duplicate chardev" here. The problem is a duplicate
monitor ID. Moreover, the message provides no clue which option
caused the problem. The patch changes the message to:
qemu: --monitor stdio: Duplicate ID 'compat_monitor0' for mon
monitor_parse() is also used for creating a default monitor, but
that's not done when the user specifies a monitor, so an ID clash is
impossible then.

block: Give always priority to unused entries in the qcow2 L2 cache
The current algorithm to replace entries from the L2 cache gives
priority to newer hits by dividing the hit count of all existing
entries by two everytime there is a cache miss.
However, if there are several cache misses the hit count of the
existing entries can easily go down to 0. This will result in those
entries being replaced even when there are others that have never been
used.
This problem is more noticeable with larger disk images and cache
sizes, since the chances of having several misses before the cache is
full are higher.
If we make sure that the hit count can never go down to 0 again,
unused entries will always have priority.

nbd: fix max_discard/max_transfer_length
nbd_co_discard calls nbd_client_session_co_discard which uses uint32_t
as the length in bytes of the data to discard due to the following
definition:
struct nbd_request {
uint32_t magic;
uint32_t type;
uint64_t handle;
uint64_t from;
uint32_t len; <-- the length of data to be discarded, in bytes
} QEMU_PACKED;
Thus we should limit bl_max_discard to UINT32_MAX >> BDRV_SECTOR_BITS to
avoid overflow.
NBD read/write code uses the same structure for transfers. Fix
max_transfer_length accordingly.

nbd: Improve error messages
This patch makes use of the Error object for nbd_receive_negotiate() so
that errors during negotiation look nicer.
Furthermore, this patch adds an additional error message if the received
magic was wrong, but would be correct for the other protocol version,
respectively: So if an export name was specified, but the NBD server
magic corresponds to an old handshake, this condition is explicitly
signaled to the user, and vice versa.
As these messages are now part of the "Could not open image" error
message, additional filtering has to be employed in iotest 083, which
this patch does as well.

iotests: Fix 104 for NBD
_make_test_img sets up an NBD server, _cleanup_test_img shuts it down;
thus, _cleanup_test_img has to be called before _make_test_img is
invoked another time.
Furthermore, the pipe through _filter_test_img was unnecessary;
_make_test_img already takes care of that.
And finally, a filter is added to _filter_img_info to replace
"nbd://127.0.0.1:10810" by "TEST_DIR/t.IMGFMT", since the former is the
way to express the full image path (normally the latter) for NBD tests.

iotests: Fix 083
As of 8f9e835fd2e687d2bfe936819c3494af4343614d, probing should be
disabled in the qemu-iotests (at least when using qemu-io). This broke
083's reference output (which consisted mostly of "Could not read image
for determining its format").
This patch fixes it.
Note that one case which failed before is now successful: Disconnect
after data. This is due to qemu having read twice before (once for
probing, once for the qemu-io read command), but only once now (the
qemu-io read command). Therefore, reading is successful (which is
correct).

block/dmg: support bzip2 block entry types
This patch adds support for bzip2-compressed block entries as introduced
with OS X 10.4 (source: https://en.wikipedia.org/wiki/Apple_Disk_Image).
It was tested against a 5.2G "OS X Yosemite" installation image which
stores the BLXX block in the XML property list (instead of resource
forks) and has over 5k chunks.
New configure entries are added (--enable-bzip2 / --disable-bzip2) to
control inclusion of bzip2 functionality (which requires linking against
libbz2). The help message suggests that this option is needed for DMG
files, but the tests are generic enough that other parts of QEMU can use
bzip2 if needed.
The identifiers are based on http://newosxbook.com/DMG.html.
The decompression routines are based on the zlib case, but as there is
no way to reset the decompression state (unlike zlib), memory is
allocated and deallocated for every decompression. This should not be
problematic as the decompression takes most of the time and as blocks
are typically about/over 1 MiB in size, only one allocation is done
every 2000 sectors.

block/dmg: factor out block type check
In preparation for adding bzip2 support, split the type check into a
separate function. Make all offsets relative to the begin of a chunk
such that it is easier to recognize the position without having to
add up all offsets. Some comments are added to describe the fields.
There is no functional change.

block/dmg: use SectorNumber from BLKX header
Previously the sector table parsing relied on the previous offset of
the DMG file. Now it uses the sector number from the BLKX header
(see http://newosxbook.com/DMG.html).
The implementation of dmg2img (from vu1tur) does not base the output
sector on the location of the terminator (0xffffffff) either so it
should be safe to drop this dependency on the previous state.
(It makes somehow makes sense, a terminator should halt further
processing of a block and is perhaps used to preallocate some space.)

block/dmg: fix sector data offset calculation
This patch addresses two issues:
- The data fork offset was not taken into account, resulting in failure
to read an InstallESD.dmg file (5164763151 bytes) which had a
non-zero DataForkOffset field.
- The offset of the previous block ("partition") was unconditionally
added to the current block because older files would start the input
offset of a new block at zero. Newer files (including vlc-2.1.5.dmg,
tuxpaint-0.9.15-macosx.dmg and OS X Yosemite [MAS].dmg) failed in
reads because these files have chunk offsets, relative to the begin
of a data fork.
Now the data offset of the mish is taken into account. While we could
check that the data_offset is within the data fork, let's not do that
here as it would only result in parse failures on invalid files (rather
than gracefully handling such bad files). dmg_read will error out if
the offset is incorrect.

block/dmg: set virtual size to a non-zero value
Right now the virtual size is always reported as zero which makes it
impossible to convert between formats.
After this patch, the number of sectors will be read from the trailer
("koly" block).
To verify the behavior, the output of `dmg2img foo.dmg foo.img` was
compared against `qemu-img convert -f dmg -O raw foo.dmg foo.raw`. The
tests showed that the file contents are exactly the same, except that
QEMU creates a slightly larger file (it matches the total sectors
count).

block/dmg: process XML plists
The format is simple enough to avoid using a full-blown XML parser. It

block.
The offsets are based on the description at

For compatibility with glib 2.12, use g_base64_decode (which
additionally requires an extra buffer allocation) instead of

block/dmg: extract processing of resource forks
Besides the offset, also read the resource length. This length is now
used in the extracted function to verify the end of the resource fork
against "count" from the resource fork.
Instead of relying on the value of offset to conclude whether the
resource fork is available or not (info_begin==0), check the
rsrc_fork_length instead. This would allow a dmg file to begin with a
resource fork. This seemingly unnecessary restriction was found while
trying to craft a DMG file by hand.
Other changes:
- Do not require resource data offset to be 0x100 (but check that it
is within bounds though).
- Further improve boundary checking (resource data must be within
the resource fork).
- Use correct value for resource data length (spotted by John Snow)
- Consider the resource data offset when determining info_end.
This fixes an EINVAL on the tuxpaint dmg example.

block/dmg: extract mish block decoding functionality
Extract the mish block decoder such that this can be used for other
formats in the future. A new DmgHeaderState struct is introduced to
share state while decoding.
The code is kept unchanged as much as possible, a "fail" label is added
for example where a simple return would probably do. In dmg_open, the
variable "tmp" is renamed to "rsrc_data_offset" for clarity and comments
have been added explaining various data.
Note that this patch has one subtle difference with the previous
version which should not affect functionality. In the previous code,
the end of a resource was inferred from the mish block (the offsets
would be increased by the fields). In this patch, the resource length
is used instead to avoid the need to rely on the previous offsets.

block/dmg: properly detect the UDIF trailer
DMG files have a variable length with a UDIF trailer at the end of a
file. This UDIF trailer is essential as it describes the contents of
the image. At the moment however, the start of this trailer is almost
always incorrect as bdrv_getlength() returns a multiple of the block
size (rounded up). This results in a failure to recognize DMG files,
resulting in Invalid argument (EINVAL) errors.
As there is no API to retrieve the real file size, look for the magic
header in the last two sectors to find the start of this 512-byte UDIF
trailer (the "koly" block).
The resource fork offset ("info_begin") has its offset adjusted as the
initial value of offset does not mean "end of file" anymore, but "begin
of UDIF trailer".
[Replaced error_set(errp, ERROR_CLASS_GENERIC_ERROR, ...) with
error_setg(errp, ...) as discussed with Peter.

block: add event when disk usage exceeds threshold
Managing applications, like oVirt (http://www.ovirt.org), make extensive
use of thin-provisioned disk images.
To let the guest run smoothly and be not unnecessarily paused, oVirt sets
a disk usage threshold (so called 'high water mark') based on the occupation
of the device, and automatically extends the image once the threshold
is reached or exceeded.
In order to detect the crossing of the threshold, oVirt has no choice but
aggressively polling the QEMU monitor using the query-blockstats command.
This lead to unnecessary system load, and is made even worse under scale:
deployments with hundreds of VMs are no longer rare.
To fix this, this patch adds:
* A new monitor command `block-set-write-threshold', to set a mark for
a given block device.
* A new event `BLOCK_WRITE_THRESHOLD', to report if a block device
usage exceeds the threshold.
* A new `write_threshold' field into the `BlockDeviceInfo' structure,
to report the configured threshold.
This will allow the managing application to use smarter and more
efficient monitoring, greatly reducing the need of polling.
[Updated qemu-iotests 067 output to add the new 'write_threshold'
property. --Stefan]
[Changed g_assert_false() to !g_assert() to fix the build on older glib
versions. --Kevin]

this patch finally introduces multiread support to virtio-blk. While
multiwrite support was there for a long time, read support was missing.
The complete merge logic is moved into virtio-blk.c which has
been the only user of request merging ever since. This is required
to be able to merge chunks of requests and immediately invoke callbacks
for those requests. Secondly, this is required to switch to
direct invocation of coroutines which is planned at a later stage.
The following benchmarks show the performance of running fio with
4 worker threads on a local ram disk. The numbers show the average
of 10 test runs after 1 run as warmup phase.

block: use fallocate(FALLOC_FL_PUNCH_HOLE) & fallocate(0) to write zeroes
This sequence works efficiently if FALLOC_FL_ZERO_RANGE is not supported.
Unfortunately, FALLOC_FL_ZERO_RANGE is supported on really modern systems
and only for a couple of filesystems. FALLOC_FL_PUNCH_HOLE is much more
mature.
The sequence of 2 operations FALLOC_FL_PUNCH_HOLE and 0 is necessary due
to the following reasons:
- FALLOC_FL_PUNCH_HOLE creates a hole in the file, the file becomes
sparse. In order to retain original functionality we must allocate
disk space afterwards. This is done using fallocate(0) call
- fallocate(0) without preceeding FALLOC_FL_PUNCH_HOLE will do nothing
if called above already allocated areas of the file, i.e. the content
will not be zeroed
This should increase the performance a bit for not-so-modern kernels.

block/raw-posix: call plain fallocate in handle_aiocb_write_zeroes
There is a possibility that we are extending our image and thus writing
zeroes beyond the end of the file. In this case we do not need to care
about the hole to make sure that there is no data in the file under
this offset (pre-condition to fallocate(0) to work). We could simply call
fallocate(0).
This improves the performance of writing zeroes even on really old
platforms which do not have even FALLOC_FL_PUNCH_HOLE.
Before the patch do_fallocate was used when either
CONFIG_FALLOCATE_PUNCH_HOLE or CONFIG_FALLOCATE_ZERO_RANGE are defined.
Now the story is different. CONFIG_FALLOCATE is defined when Linux
fallocate is defined, posix_fallocate is completely different story
(CONFIG_POSIX_FALLOCATE). CONFIG_FALLOCATE is mandatory prerequite
for both CONFIG_FALLOCATE_PUNCH_HOLE and CONFIG_FALLOCATE_ZERO_RANGE
thus we are on the safe side.

atapi migration: Throw recoverable error to avoid recovery
(With the previous atapi_dma flag recovery)
If migration happens between the ATAPI command being written and the
bmdma being started, the DMA is dropped. Eventually the guest times
out and recovers, but that can take many seconds.
(This is rare, on a pingpong reading the CD continuously I hit
this about ~1/30-1/50 migrates)
I don't think we've got enough state to be able to recover safely
at this point, so I throw a 'medium error, no seek complete'
that I'm assuming guests will try and recover from an apparently
dirty CD.
OK, it's a hack, the real solution is probably to push a lot of
ATAPI state into the migration stream, but this is a fix that
works with no stream changes. Tested only on Linux (both RHEL5
(pre-libata) and RHEL7).

Restore atapi_dma flag across migration
If a migration happens just after the guest has kicked
off an ATAPI command and kicked off DMA, we lose the atapi_dma
flag, and the destination tries to complete the command as PIO
rather than DMA. This upsets Linux; modern libata based kernels
stumble and recover OK, older kernels end up passing bad data
to userspace.

rtl8139: simplify timer logic
Pavel Dovgalyuk reports that TimerExpire and the timer are not restored
correctly on the receiving end of migration.
It is not clear to me whether this is really the case, but we can take
the occasion to get rid of the complicated code that computes PCSTimeout
on the fly upon changes to IntrStatus/IntrMask. Just always keep a
timer running, it will fire every ~130 seconds at most if the interrupt
is masked with TimerInt != 0.
This makes rtl8139_set_next_tctr_time idempotent (when the virtual clock
is stopped between two calls, as is the case during migration).
Tested with Frediano's qtest.

migration: Append JSON description of migration stream
One of the annoyances of the current migration format is the fact that
it's not self-describing. In fact, it's not properly describing at all.
Some code randomly scattered throughout QEMU elaborates roughly how to
read and write a stream of bytes.
We discussed an idea during KVM Forum 2013 to add a JSON description of
the migration protocol itself to the migration stream. This patch
adds a section after the VM_END migration end marker that contains
description data on what the device sections of the stream are composed of.
This approach is backwards compatible with any QEMU version reading the
stream, because QEMU just stops reading after the VM_END marker and ignores
any data following it.
With an additional external program this allows us to decipher the
contents of any migration stream and hopefully make migration bugs easier
to track down.

qemu-file: Add fast ftell code path
For ftell we flush the output buffer to ensure that we don't have anything
lingering in our internal buffers. This is a very safe thing to do.
However, with the dynamic size measurement that the dynamic vmstate
description will bring this would turn out quite slow.
Instead, we can fast path this specific measurement and just take the
internal buffers into account when telling the kernel our position.
I'm sure I overlooked some corner cases where this doesn't work, so
instead of tuning the safe, existing version, this patch adds a fast
variant of ftell that gets used by the dynamic vmstate description code
which isn't critical when it fails.

QJSON: Add JSON writer
To support programmatic JSON assembly while keeping the code that generates it
readable, this patch introduces a simple JSON writer. It emits JSON serially
into a buffer in memory.
The nice thing about this writer is its simplicity and low memory overhead.
Unlike the QMP JSON writer, this one does not need to spawn QObjects for every
element it wants to represent.
This is a prerequisite for the migration stream format description generator.

coverity: Model g_free() isn't necessarily free()
Memory allocated with GLib needs to be freed with GLib. Freeing it
with free() instead of g_free() is a common error. Harmless when
g_free() is a trivial wrapper around free(), which is commonly the
case. But model the difference anyway.

coverity: Model GLib string allocation partially
Without a model, Coverity can't know that the result of g_strdup()
needs to be fed to g_free().
One way to get such a model is to scan GLib, build a derived model
file with cov-collect-models, and use that when scanning QEMU.
Unfortunately, the Coverity Scan service we use doesn't support that.
Thus, we're stuck with the other way: write a user model. Doing that
for all of GLib is hardly practical. I'm doing it for the "String
Utility Functions" we actually use that return dynamically allocated
strings.
In a local scan, this flags 20 additional RESOURCE_LEAKs. The ones I
checked look genuine.
It also loses a NULL_RETURNS about ppce500_init() using
qemu_find_file() without error checking. I don't understand why.

coverity: Improve model for GLib memory allocation
In current versions of GLib, g_new() may expand into g_malloc_n().
When it does, Coverity can't see the memory allocation, because we
don't model g_malloc_n(). Similarly for g_new0(), g_renew(),
g_try_new(), g_try_new0(), g_try_renew().
Model g_malloc_n(), g_malloc0_n(), g_realloc_n(). Model
g_try_malloc_n(), g_try_malloc0_n(), g_try_realloc_n() by adding
indeterminate out of memory conditions on top.
To avoid undue duplication, replace the existing models for g_malloc()
& friends by trivial wrappers around g_malloc_n() & friends.
In a local scan, this flags four additional RESOURCE_LEAKs and one
NULL_RETURNS.
The NULL_RETURNS is a false positive: Coverity can now see that
g_try_malloc(l1_sz * sizeof(uint64_t)) in
qcow2_check_metadata_overlap() may return NULL, but is too stupid to
recognize that a loop executing l1_sz times won't be entered then.
Three out of the four RESOURCE_LEAKs appear genuine. The false
positive is in ppce500_prep_device_tree(): the pointer dies, but a
pointer to a struct member escapes, and we get the pointer back for
freeing with container_of(). Too funky for Coverity.

target-arm: Guest cpu endianness determination for virtio KVM ARM/ARM64
This patch implements a fucntion pointer "virtio_is_big_endian"
from "CPUClass" structure for arm/arm64.
Function arm_cpu_is_big_endian() is added to determine and
return the guest cpu endianness to virtio.
This is required for running cross endian guests with virtio on ARM/ARM64.

translations when we properly support EL2.
Define and document all seven mmu index values that we require, and
pass the mmu index in the TB flags rather than exception level or
priv/user bit.
This change doesn't update the get_phys_addr() code, so our page

target-arm: check that LSB <= MSB in BFI instruction
The documentation states that if LSB > MSB in BFI instruction behaviour
is unpredictable. Currently QEMU crashes because of assertion failure in
this case:
tcg/tcg-op.h:2061: tcg_gen_deposit_i32: Assertion `len <= 32' failed.
While assertion failure may meet the "unpredictable" definition this
behaviour is undesirable because it allows an unprivileged guest program
to crash the emulator with the OS and other programs.
This patch addresses the issue by throwing illegal instruction exception
if LSB > MSB. Only ARM decoder is affected because Thumb decoder already
has this check in place.
To reproduce issue run the following program
int main(void) {
asm volatile (".long 0x07c00c12" :: );
return 0;
}

target-arm: Split NO_MIGRATE into ALIAS and NO_RAW
We currently mark ARM coprocessor/system register definitions with
the flag ARM_CP_NO_MIGRATE for two different reasons:
1) register is an alias on to state that's also visible via
some other register, and that other register is the one
responsible for migrating the state
2) register is not actually state at all (for instance the TLB
or cache maintenance operation "registers") and it makes no
sense to attempt to migrate it or otherwise access the raw state
This works fine for identifying which registers should be ignored
when performing migration, but we also use the same functions for
synchronizing system register state between QEMU and the kernel
when using KVM. In this case we don't want to try to sync state
into registers in category 2, but we do want to sync into registers
in category 1, because the kernel might have picked a different
one of the aliases as its choice for which one to expose for
migration. (In particular, on 32 bit hosts the kernel will
expose the state in the AArch32 version of the register, but
TCG's convention is to mark the AArch64 version as the version
to migrate, even if the CPU being emulated happens to be 32 bit,
so almost all system registers will hit this issue now that we've
added AArch64 system emulation.)
Fix this by splitting the NO_MIGRATE flag in two (ALIAS and NO_RAW)
corresponding to the two different reasons we might not want to
migrate a register. When setting up the TCG list of registers to
migrate we honour both flags; when populating the list from KVM,
only ignore registers which are NO_RAW.

vfio-pci: Fix missing unparent of dynamically allocated MemoryRegion
Commit d8d95814609e added explicit object_unparent() calls for
dynamically allocated MemoryRegions. The VFIOMSIXInfo structure also
contains such a MemoryRegion, covering the mmap'd region of a PCI BAR
above the MSI-X table. This structure is freed as part of the class
exit function and therefore also needs an explicit object_unparent().
Failing to do this results in random segfaults due to fields within
the structure, often the class pointer, being reclaimed and corrupted
by the time object_finalize_child_property() is called for the object.

target-s390x: fix and optimize slb* and slbg* computation of carry/borrow flag
This patch fixes the bug with borrow_in being set incorrectly, but it
also simplifies the logic to be much more plain, improving speed. It
fixes both the 32-bit SLB* and 64-bit SLBG*.
The SLBG* change has been well-tested. I haven't tested the SLB* change
explicitly, but the code was copy-pasted from the tested code.
The error of these functions' current implementations would not likely
be triggered by compiler-generated code, since the only error was in the
state of the carry/borrow flag. Compilers rarely generate an
instruction sequence such as carry-set -> carry-set-and-use ->
carry-use.
(With Paolo's fix and mine, there are still a couple of failures from
GMP's testsuite, but they are almost surely due to incorrect code
generation from gcc 4.9. But since this gcc is running under qemu, it
might be qemu bugs. I intend to investigate this.)

s390x/kvm: unknown DIAGNOSE code should give a specification exception
As described in CP programming services an unimplemented DIAGNOSE
function should return a specification exception. Today we give the
guest an operation exception.
As both exception types are suppressing and Linux as a guest does not
care about the type of program check in its exception table handler
as long as both types have the same kind of error handling (nullifying,
terminating, suppressing etc.) this was unnoticed.

rcu: add call_rcu
Asynchronous callbacks provided by call_rcu are particularly important
for QEMU, because the BQL makes it hard to use synchronize_rcu.
In addition, the current RCU implementation is not particularly friendly
to multiple concurrent synchronize_rcu callers, making call_rcu even
more important.

rcu: add rcu library
This includes a (mangled) copy of the liburcu code. The main changes
are: 1) removing dependencies on many other header files in liburcu; 2)
removing for simplicity the tentative busy waiting in synchronize_rcu,
which has limited performance effects; 3) replacing futexes in
synchronize_rcu with QemuEvents for Win32 portability. The API is
the same as liburcu, so it should be possible in the future to require
liburcu on POSIX systems for example and use our copy only on Windows.
Among the various versions available I chose urcu-mb, which is the
least invasive implementation even though it does not have the
fastest rcu_read_{lock,unlock} implementation. The urcu flavor can
be changed later, after benchmarking.

Revert the parts of commits b645bb4885 and 5a6932d51d which are still

Reimplement support for architectures where the most significant bit
in the mantissa is 1 for a signaling NaN rather than a quiet NaN,
by adding handling for SNAN_BIT_IS_ONE being set to the functions
which test values for NaN-ness.
This includes restoring the bugfixes lost in the reversion where
some of the float*_is_quiet_nan() functions were returning true
for both signaling and quiet NaNs.

linux-user: Fix broken m68k signal handling on 64 bit hosts
The m68k signal frame setup code which writes the signal return
trampoline code to the stack was assuming that a 'long' was 32 bits;
on 64 bit systems this meant we would end up writing the 32 bit
(2 insn) trampoline sequence to retaddr+4,retaddr+6 instead of
the intended retaddr+0,retaddr+2, resulting in a guest crash when
it tried to execute the invalid zero-bytes at retaddr+0.
Fix by using uint32_t instead; also use uint16_t rather than short
for consistency. This fixes bug LP:1404690.

linux-user: Fix ioctl cmd type mismatch on 64-bit targets
linux-user passes the cmd argument of the ioctl syscall as a signed long,
but compares it to an unsigned int when iterating through the ioctl_entries
list. When the cmd is a large value like 0x80047476 (TARGET_TIOCSWINSZ on
mips64) it gets sign-extended to 0xffffffff80047476, causing the comparison
to fail and resulting in lots of spurious "Unsupported ioctl" errors.
Changing the target_cmd field in the ioctl_entries list to a signed int
causes those values to be sign-extended as well during the comparison.

linux-user/signal.c: Remove unnecessary wrapper copy_siginfo_to_user
The function copy_siginfo_to_user() just calls tswap_siginfo(), so
call the latter function directly and delete the wrapper function.
The wrapper is actually misleading since it implies that the
semantics are like the kernel function with the same name which
copies the data to a guest user-space address. In fact tswap_siginfo()
just does data-structure conversion between two structures whose
addresses are host addresses (the copy to userspace is handled
in QEMU by the lock_user/unlock_user calls).
This also fixes clang complaints about the wrapper being unused
in some configs.

linux-user/alpha: Add define for NR_shmat to enable shmat syscall
For historical reasons, the define for the shmat() syscall on Alpha is
NR_osf_shmat; however it has the same semantics as this syscall does
on all other architectures, so define TARGET_NR_shmat as well so that
QEMU's code for the syscall is enabled.
This patch brings our behaviour on the LTP shmat tests into line
with that for ARM (still not a perfect pass rate but not "this syscall
is completely broken" as we had before).
(Problem detected via a clang warning that the do_shmat() function
was unused on Alpha.)

linux-user/signal.c: Remove current_exec_domain_sig()
Remove the function current_exec_domain_sig(), which always returns
its argument. This was intended as a stub for supporting the kernel's
exec_domain handling, but:
* we don't have any of the other code for execution domains
* in the kernel this handling is architecture-specific, not generic
* we only call this function in the x86, ppc and sh4 signal code paths,
and the PPC one is wrong anyway because the PPC kernel doesn't
have this signal-remapping code
So it's best to simply delete the function; any future attempt to
implement exec domains will be better served by adding the correct
code from scratch based on the kernel sources at that time.
This change also fixes some clang warnings about the function being
defined but not used for some target architectures.

target-tricore: split up suov32 into suov32_pos and suov32_neg
suov checks unsigned for an overflow and an underflow, after some arithmetic
operations and saturates the result to either max_uint32 or 0. So far we
handled this by expanding to the next bigger data type and compare whether
the result is > max_uint32 or < 0.
However this approach can fail for an 32 bit multiplication, if both operands of
the multiplication are 0x80000000. This sets the sign bit of the 64 bit integer
and would result in a false saturation to 0.
Since unsigned operations, e.g add, sub, mul always result in either a positive
or negative overflow, we split the functions for suov32 up into two functions
(suov32_pos, suov32_neg) for each case.

pci: Split pcie_host_mmcfg_map()
The mmcfg space is a memory region that allows access to PCI config space
in the PCIe world. To maintain abstraction layers, I would like to expose
the mmcfg space as a sysbus mmio region rather than have it mapped straight
into the system's memory address space though.
So this patch splits the initialization of the mmcfg space from the actual
mapping, allowing us to only have an mmfg memory region without the map.

ich9: add disable_s3, disable_s4, s4_val properties
PIIX4 has disable_s3 and disable_s4 properties to enable or disable PM
functions. Add such properties to the ICH9 chipset as well for the Q35
machine type.
S3 / S4 are not guaranteed to always work (needs work in the guest as
well as QEMU for things to work properly), and disabling advertising of
these features ensures guests don't go into zombie state if something
isn't working right.
The defaults are kept the same as in PIIX4: both S3 and S4 are enabled
by default.
These can be disabled via the cmdline:
... -global ICH9-LPC.disable_s3=1 -global ICH9-LPC.disable_s4=1
Note: some guests can fake hibernation by writing a hibernate image and
doing a shutdown instead of S4 if S4 isn't available; there's nothing we
can do guests to stop doing this, and this patch can't affect that
functionality.

qemu-timer.c: Trim list of included headers
qemu-timer.c was including a lot more headers than it needed to,
presumably for historical reasons. In particular, it included
ui/console.h; this now tries to pull in <pixman.h>, which will
cause a compilation failure in --disable-tools --disable-system
configurations when running "make check" (which builds qemu-timer.c,
even though the linux-user binaries themselves don't need it).
Fix this build failure by trimming down the set of included
headers severely -- we only really need main-loop.h and timer.h.

kvm_stat: Add RESET support for perf event ioctl
While running kvm_stat using tracepoint on ARM64 hardware (e.g. "kvm_stat
-1 -t"), the initial values of some kvm_userspace_exit counters were found
to be very suspecious. For instance the tracing tool showed that S390_TSCH
was called many times on ARM64 machine, which apparently was wrong.
This patch adds RESET ioctl support for perf monitoring. Before calling
ioctl to enable a perf event, this patch resets the counter first. With
this patch, the init counter values become correct on ARM64 hardware.
Example:
==== before patch ====
kvm_userspace_exit(S390_SIEIC) 1426 0
kvm_userspace_exit(S390_TSCH) 339 0
==== after patch ====
kvm_userspace_exit(S390_SIEIC) 0 0

apic: do not dereference pointer before it is checked for NULL
Right now you only get to apic_init_reset if you have an APIC
(do_cpu_init is reached only if CPU_INTERRUPT_INIT is set and
that only happens in hw/intc/apic.c). However, this is wrong
because for example a port 92 or keyboard controller reset is
really an INIT, and that can happen also with no APIC. So
keep the check and fix the error that Coverity reported.

kvm_stat: Print errno when syscall to perf_event_open() fails
kvm_stat uses syscall() to call perf_event_open(). If this function
call fails, the returned value is -1, which doesn't tell the details
of such failure (i.e. ENOSYS or EINVAL). This patch retrieves errno
and prints it when syscall() fails. The error message will look like

qemu-timer: introduce timer_deinit
In some cases, a timer was set to NULL so that we could check if it is
initialized. Use the timer_list field instead, and add a timer_deinit
function that NULLs it.
It then makes sense that timer_del be a no-op (instead of a crasher) on
such a de-initialized timer. It avoids the need to poke at the timerlist
field to check if the timers are initialized.

target-i386: make xmm_regs 512-bit wide
Right now, the AVX512 registers are split in many different fields:
xmm_regs for the low 128 bits of the first 16 registers, ymmh_regs
for the next 128 bits of the same first 16 registers, zmmh_regs
for the next 256 bits of the same first 16 registers, and finally
hi16_zmm_regs for the full 512 bits of the second 16 bit registers.
This makes it simple to move data in and out of the xsave region,
but would be a nightmare for a hypothetical TCG implementation and
leads to a proliferation of [XYZ]MM_[BWLSQD] macros. Instead,
this patch marshals data manually from the xsave region to a single
32x512-bit array, simplifying the macro jungle and clarifying which
bits are in which vmstate subsection.
The migration format is unaffected.

target-i386: use vmstate_offset_sub_array for AVX registers
After the next patch, each vmstate field will extract parts of a larger
(32x512-bit) array, so we cannot check the vmstate field against the
type of the array.
While changing this, change the macros to accept the index of the first
element (which will not be 0 for Hi16_ZMM_REGS) instead of the number
of elements (which is always CPU_NB_REGS).

block: vhdx - force FileOffsetMB field to '0' for certain block states
The v1.0.0 spec calls out PAYLOAD_BLOCK_ZERO FileOffsetMB field as being
'reserved'. In practice, this means that Hyper-V will fail to read a
disk image with PAYLOAD_BLOCK_ZERO block states with a FileOffsetMB
value other than 0.
The other states that indicate a block that is not there
(PAYLOAD_BLOCK_UNDEFINED, PAYLOAD_BLOCK_NOT_PRESENT,
PAYLOAD_BLOCK_UNMAPPED) have multiple options for what FileOffsetMB may
be set to, and '0' is explicitly called out as an option.
For all the above states, we will also just set the FileOffsetMB value
to 0.

block: update string sizes for filename,backing_file,exact_filename
The string field entries 'filename', 'backing_file', and
'exact_filename' in the BlockDriverState struct are defined as 1024
bytes.
However, many places that use these values accept a maximum of PATH_MAX
bytes, so we have a mixture of 1024 byte and PATH_MAX byte allocations.
This patch makes the BlockDriverStruct field string sizes match usage.
This patch also does a few fixes related to the size that needs to
happen now:
* the block qapi driver is updated to use PATH_MAX bytes
* the qcow and qcow2 drivers have an additional safety check
* the block vvfat driver is updated to use PATH_MAX bytes
for the size of backing_file, for systems where PATH_MAX is < 1024
bytes.
* qemu-img uses PATH_MAX rather than 1024. These instances were not
changed to be dynamically allocated, however, as the extra
temporary 3K in stack usage for qemu-img does not seem worrisome.

block: mirror - change string allocation to 2-bytes
The backing_filename string in mirror_run() is only used to check

PATH_MAX bytes), when we only need to copy the first 2 characters.
We technically only need 1 byte, as we are just checking for NULL, but
since backing_filename[] is populated by bdrv_get_backing_filename(), a
string size of 1 will always only return '\0';

hw/input/hid.c Fix capslock hid code
When ever USB keyboard is used, e.g. '-usbdevice keyboard' pressing
caps lock key send 0x32 hid code, which is treated as backslash.
Instead it should be 0x39 code. This affects sending uppercase keys,
as they typed whith caps lock active.
While on x86 this can be workarounded by using ps/2 protocol. On
Power it is crusial as we don't have anything else than USB.
This is fixes guest automation tasts over vnc.

monitor: add query-vnc-servers command
Add new query vnc qmp command, for the lack of better ideas just name it
"query-vnc-servers". Changes over query-vnc:
* It returns a list of vnc servers, so multiple vnc server instances
are covered.
* Each vnc server returns a list of server sockets. Followup patch
will use that to also report websockets. In case we add support for
multiple server sockets server sockets (to better support ipv4+ipv6
dualstack) we can add them to the list too.

vnc: track & limit connections
Also track the number of connections in "connecting" and "shared" state
(in addition to the "exclusive" state). Apply a configurable limit to
these connections.
The logic to apply the limit to connections in "shared" state is pretty
simple: When the limit is reached no new connections are allowed.
The logic to apply the limit to connections in "connecting" state (this
is the state you are in *before* successful authentication) is
slightly different: A new connect kicks out the oldest client which is
still in "connecting" state. This avoids a easy DoS by unauthenticated
users by simply opening connections until the limit is reached.

sb16: fix interrupt acknowledgement
SoundBlaster 16 emulation is very broken and consumes a lot of CPU, but a
small fix was suggested offlist and it is enough to fix some games. I
got Epic Pinball to work with the "SoundBlaster Clone" option.
The processing of the interrupt register is wrong due to two missing
"not"s. This causes the interrupt flag to remain set even after the
Acknowledge ports have been read (0x0e and 0x0f).
The line was introduced by commit 85571bc (audio merge (malc), 2004-11-07),
but the code might have been broken before because I did not look closely
at the huge patches from 10 years ago.

Not all targets define a full set of suffix strings for the

with no suffix at all. The MMU mode is still functional; it is merely
not directly accessible via cpu_ld*_MODE from target helper functions.

helpers -- some targets only define one MMU mode.

Use inline functions rather than macros for cpu_ld/st accessors

This has a two advantages:
* we can actually typecheck our arguments
* we don't need to leak the _raw macros everywhere
Since the _kernel functions were only used by target-i386/seg_helper.c,
put the definitions for them in that file too. (It already has the
similar template include code to define them for the softmmu case,
so it makes sense to have it deal with defining them for user-only.)

The monitor code for doing a memory_dump() was using ld*_raw() to do
target-CPU accesses out of a local buf[] array. The correct functions
for this purpose are ld*_p(), which take a host pointer, rather than
ld*_raw(), which take an integer representing a guest address and
are somewhat meaningless in softmmu configurations. Nobody noticed
because for softmmu the _raw functions are the same as ldl_p but
with some extra casts thrown in. Switch to using the correct functions
instead.

Make sure that all generated C structs have at least one field; this

zero-length structs in C (g_malloc(sizeof struct) would return NULL).
It also avoids an incompatibility with C++ (where an empty struct is
size 1); that isn't important to us now but might be in future.
Generated empty structures look like this:
struct Abort
{
char qapi_dummy_field_for_empty_struct;

Xen: Use the ioreq-server API when available
The ioreq-server API added to Xen 4.5 offers better security than
the existing Xen/QEMU interface because the shared pages that are
used to pass emulation request/results back and forth are removed
from the guest's memory space before any requests are serviced.
This prevents the guest from mapping these pages (they are in a
well known location) and attempting to attack QEMU by synthesizing
its own request structures. Hence, this patch modifies configure
to detect whether the API is available, and adds the necessary
code to use the API if it is.

fw_cfg: fix endianness in fw_cfg_data_mem_read() / _write()
target-arm: crypto: fix BE host support
Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
commit 36b62ae6a58f9a588fd33be9386e18a2b90103f5
Author: Laszlo Ersek <lersek@redhat.com>
Date: Fri Jan 16 11:54:30 2015 +0000
fw_cfg: fix endianness in fw_cfg_data_mem_read() / _write()
(1) Let's contemplate what device endianness means, for a memory mapped
device register (independently of QEMU -- that is, on physical hardware).
It determines the byte order that the device will put on the data bus when
the device is producing a *numerical value* for the CPU. This byte order
may differ from the CPU's own byte order, therefore when software wants to
consume the *numerical value*, it may have to swap the byte order first.
For example, suppose we have a device that exposes in a 2-byte register
the number of sheep we have to count before falling asleep. If the value
is decimal 37 (0x0025), then a big endian register will produce [0x00,
0x25], while a little endian register will produce [0x25, 0x00].
If the device register is big endian, but the CPU is little endian, the
numerical value will read as 0x2500 (decimal 9472), which software has to
byte swap before use.
However... if we ask the device about who stole our herd of sheep, and it
answers "XY", then the byte representation coming out of the register must
be [0x58, 0x59], regardless of the device register's endianness for
numeric values. And, software needs to copy these bytes into a string
field regardless of the CPU's own endianness.
(2) QEMU's device register accessor functions work with *numerical values*
exclusively, not strings:
The emulated register's read accessor function returns the numerical value
(eg. 37 decimal, 0x0025) as a *host-encoded* uint64_t. QEMU translates
this value for the guest to the endianness of the emulated device register
(which is recorded in MemoryRegionOps.endianness). Then guest code must
translate the numerical value from device register to guest CPU
endianness, before including it in any computation (see (1)).
(3) However, the data register of the fw_cfg device shall transfer strings
*only* -- that is, opaque blobs. Interpretation of any given blob is
subject to further agreement -- it can be an integer in an independently
determined byte order, or a genuine string, or an array of structs of
integers (in some byte order) and fixed size strings, and so on.
Because register emulation in QEMU is integer-preserving, not
string-preserving (see (2)), we have to jump through a few hoops.
(3a) We defined the memory mapped fw_cfg data register as
DEVICE_BIG_ENDIAN.
The particular choice is not really relevant -- we picked BE only for
consistency with the control register, which *does* transfer integers --
but our choice affects how we must host-encode values from fw_cfg strings.
(3b) Since we want the fw_cfg string "XY" to appear as the [0x58, 0x59]
array on the data register, *and* we picked DEVICE_BIG_ENDIAN, we must
compose the host (== C language) value 0x5859 in the read accessor
function.
(3c) When the guest performs the read access, the immediate uint16_t value
will be 0x5958 (in LE guests) and 0x5859 (in BE guests). However, the
uint16_t value does not matter. The only thing that matters is the byte
pattern [0x58, 0x59], which the guest code must copy into the target
string *without* any byte-swapping.
(4) Now I get to explain where I screwed up. :(
When we decided for big endian *integer* representation in the MMIO data
register -- see (3a) --, I mindlessly added an indiscriminate
byte-swizzling step to the (little endian) guest firmware.
This was a grave error -- it violates (3c) --, but I didn't realize it. I
only saw that the code I otherwise intended for fw_cfg_data_mem_read():
value = 0;
for (i = 0; i < size; ++i) {
value = (value << 8) | fw_cfg_read(s);
}
didn't produce the expected result in the guest.
In true facepalm style, instead of blaming my guest code (which violated
(3c)), I blamed my host code (which was correct). Ultimately, I coded
ldX_he_p() into fw_cfg_data_mem_read(), because that happened to work.
Obviously (...in retrospect) that was wrong. Only because my host happened
to be LE, ldX_he_p() composed the (otherwise incorrect) host value 0x5958
from the fw_cfg string "XY". And that happened to compensate for the bogus
indiscriminate byte-swizzling in my guest code.
Clearly the current code leaks the host endianness through to the guest,
which is wrong. Any device should work the same regardless of host
endianness.
The solution is to compose the host-endian representation (2) of the big
endian interpretation (3a, 3b) of the fw_cfg string, and to drop the wrong
byte-swizzling in the guest (3c).
Brown paper bag time for me.

target-arm: crypto: fix BE host support
The crypto emulation code in target-arm/crypto_helper.c never worked
correctly on big endian hosts, due to the fact that it uses a union
of array types to convert between the native VFP register size (64
bits) and the types used in the algorithms (bytes and 32 bit words)
We cannot just swab between LE and BE when reading and writing the
registers, as the SHA code performs word additions, so instead, add
array accessors for the CRYPTO_STATE type whose LE and BE specific
implementations ensure that the correct array elements are referenced.

Handle bi-directional communication for fd migration
libvirt prefers opening the TCP connection itself, for two reasons.
First, connection failed errors can be detected easier, without having
to parse qemu's error output.
Second, libvirt might be asked to secure the transfer by tunnelling the
communication through an TLS layer.
Therefore, libvirt opens the TCP connection itself and passes an FD to qemu
using QMP and a POSIX-specific mechanism.
Hence, in order to make the reverse-path work in such cases, qemu needs to
distinguish if the transmitted FD is a socket (reverse-path available)
or not (reverse-path might not be available) and use the corresponding
abstraction.

QEMUSizedBuffer: only free qsb that qemu_bufopen allocated
Only free qsb that qemu_bufopen allocated, and also allow
qemu_bufopen accept qsb as input for write operation. It
will make the API more logical:
1.If you create the QEMUSizedBuffer yourself, you need to
free it by using qsb_free() but not depends on other API
like qemu_fclose.
2.allow qemu_bufopen() accept QEMUSizedBuffer as input for
write operation, otherwise, it will be a little strange
for this API won't accept the second parameter.
This brings API change, since there are only 3
users of this API currently, this change only impact the
first one which will be fixed in patch 2 of this patchset,
so I think it is safe to do this change.

Module build is broken since commit c261d774fb ( rules.mak: Fix DSO

of DSO to -y variables, in order to pull stub symbols to executable. But
the placeholders are unintentionally expanded in -y, rather than
filtered out while linking.
Fix it by moving the -objs expanding to before inserting .mo
placeholders. Note that passing -cflags and -libs to member objects are
also moved to keep it happening before object expanding.

target-i386: do not memcpy in and out of xmm_regs
After the next patch, we will move the high parts of AVX and AVX512 registers
in the same array as the SSE registers. This will make it impossible to
memcpy an array of 128-bit values in and out of xmm_regs in one swoop.
Use a for loop instead.
Similarly, always use XMM_Q in translate.c. This avoids introducing bugs
such as the one fixed in the previous patch.

Solved by extracting the logic on a separate function and calling it
after the switch.

ide: Implement VPD response for ATAPI
SCSI devices have multiple kinds of queries they need to respond
to, as defined in the "cmd inquiry" section in MMC-6 and SPC-3.
Relevent sections:
MMC-6 revision 2g:
Non-VPD response data and pointer to SPC-3;
Section 6.8 "Inquiry Command"
SPC-3 revision 23:
Inquiry command and error handling:
Section 6.4 "INQUIRY command"
VPD data pages format:
Section 7.6 "Vital product data parameters"
We implement these Vital Product Data queries for SCSI, but not for
ATAPI through IDE. The result is that if you are looking for the WWN
identifier via tools such as sg3_utils, you will be unable to query
our CD/DVD rom device to obtain it.
This patch adds the minimum number of mandatory responses as defined
by SPC-3, which include the "supported pages" response (page 0x00)
and the "Device Identification" response (page 0x83). It also correctly
responds when it receives a request for an illegal page to improve
error output from related tools.
The Device ID page contains an arbitrary list of identification
strings of various formats; the ID strings included in this patch
were chosen to mimic those provided by the libata driver when
emulating this SCSI query (model, serial, and wwn when present.)
Example:
# libata emulated response
[root@localhost ~]# sg_inq --id /dev/sda
VPD INQUIRY: Device Identification page
Designation descriptor number 1, descriptor length: 24
designator_type: vendor specific [0x0], code_set: ASCII

block: Split BLOCK_OP_TYPE_COMMIT to BLOCK_OP_TYPE_COMMIT_{SOURCE, TARGET}
Like BLOCK_OP_TYPE_BACKUP_SOURCE and BLOCK_OP_TYPE_BACKUP_TARGET,
block-commit involves two asymmetric devices.
This change is not user-visible (yet), because commit only works with
device names.
But once we enable backing reference in blockdev-add, or specifying
node-name in block-commit command, we don't want the user to start two
commit jobs on the same backing chain, which will corrupt things because
of the final bdrv_swap.
Before we have per category blockers, splitting this type is still
better.
[Resolved virtio-blk dataplane conflict by replacing
BLOCK_OP_TYPE_COMMIT with both BLOCK_OP_TYPE_COMMIT_{SOURCE, TARGET}.
They are safe since the block job runs in the same AioContext as the
dataplane IOThread.

coroutine: try harder not to delete coroutines
Placing coroutines on the global pool should be preferrable, because it
can help all threads. But if the global pool is full, we can still
try to save some allocations by stashing completed coroutines on the
local pool. This is quite cheap too, because it does not require
atomic operations, and provides a gain of 15% in the best case.

coroutine: rewrite pool to avoid mutex
This patch removes the mutex by using fancy lock-free manipulation of
the pool. Lock-free stacks and queues are not hard, but they can suffer
from the ABA problem so they are better avoided unless you have some
deferred reclamation scheme like RCU. Otherwise you have to stick
with adding to a list, and emptying it completely. This is what this
patch does, by coupling a lock-free global list of available coroutines
with per-CPU lists that are actually used on coroutine creation.
Whenever the destruction pool is big enough, the next thread that runs
out of coroutines will steal the whole destruction pool. This is positive
in two ways:
1) the allocation does not have to do any atomic operation in the fast
path, it's entirely using thread-local storage. Once every POOL_BATCH_SIZE
allocations it will do a single atomic_xchg. Release does an atomic_cmpxchg
loop, that hopefully doesn't cause any starvation, and an atomic_inc.
A later patch will also remove atomic operations from the release path,
and try to avoid the atomic_xchg altogether---succeeding in doing so if
all devices either use ioeventfd or are not submitting requests actively.
2) in theory this should be completely adaptive. The number of coroutines
around should be a little more than POOL_BATCH_SIZE * number of allocating
threads; so this also empties qemu_coroutine_adjust_pool_size. (The previous
pool size was POOL_BATCH_SIZE * number of block backends, so it was a bit
more generous. But if you actually have many high-iodepth disks, it's better
to put them in different iothreads, which will also use separate thread
pools and aio=native file descriptors).
This speeds up perf/cost (in tests/test-coroutine) by a factor of ~1.33.
No matter if we end with some kind of coroutine bypass scheme or not,
it cannot hurt to optimize hot code.

qemu-thread: add per-thread atexit functions
Destructors are the main additional feature of pthread TLS compared
to __thread. If we were using C++ (hint, hint!) we could have used
thread-local objects with a destructor. Since we are not, instead,
we add a simple Notifier-based API.
Note that the notifier must be per-thread as well. We can add a
global list as well later, perhaps.
The Win32 implementation has some complications because a) detached
threads used not to have a QemuThreadData; b) the main thread does
not go through win32_start_routine, so we have to use atexit too.

coroutine-ucontext: use __thread
ELF thread local storage is about 10% faster on tests/test-coroutine's
perf/cost test. The timing on my machine is 190ns per iteration with
pthread TLS, 170 with ELF TLS.
Based on a patch by Kevin Wolf and Peter Lieven, but redone to follow
the model of coroutine-win32.c (including the important "noinline"
attribute!).
Platforms without thread-local storage (OpenBSD probably?) will need
a new-enough GCC for this to compile, in order to use the same emutls
support that Windows already relies on.

xen-pt: Fix PCI devices re-attach failed
Use the 'xl pci-attach $DomU $BDF' command to attach more than
one PCI devices to the guest, then detach the devices with
'xl pci-detach $DomU $BDF', after that, re-attach these PCI
devices again, an error message will be reported like following:
libxl: error: libxl_qmp.c:287:qmp_handle_error_response: receive
an error message from QMP server: Duplicate ID 'pci-pt-03_10.1'
for device.
If using the 'address_space_memory' as the parameter of
'memory_listener_register', 'xen_pt_region_del' will not be called
if the memory region's name is not 'xen-pci-pt-*' when the devices
is detached. This will cause the device's related QemuOpts object
not be released properly.
Using the device's address space can avoid such issue, because the
calling count of 'xen_pt_region_add' when attaching and the calling
count of 'xen_pt_region_del' when detaching is the same, so all the
memory region ref and unref by the 'xen_pt_region_add' and
'xen_pt_region_del' can be released properly.

migration/block: fix pending() return value
Because of wrong return value of .save_live_pending() in
migration/block.c, migration finishes before the whole disk is
transferred. Such situation occurs when the migration process is fast
enough, for example when source and dest are on the same host.
If in the bulk phase we return something < max_size, we will skip
transferring the tail of the device. Currently we have "set pending to
BLOCK_SIZE if it is zero" for bulk phase, but there no guarantee, that
it will be < max_size.
True approach is to return, for example, max_size+1 when we are in the
bulk phase.

block: fix spoiling all dirty bitmaps by mirror and migration
Mirror and migration use dirty bitmaps for their purposes, and since
commit [block: per caller dirty bitmap] they use their own bitmaps, not
the global one. But they use old functions bdrv_set_dirty and
bdrv_reset_dirty, which change all dirty bitmaps.
Named dirty bitmaps series by Fam and Snow are affected: mirroring and
migration will spoil all (not related to this mirroring or migration)
named dirty bitmaps.
This patch fixes this by adding bdrv_set_dirty_bitmap and
bdrv_reset_dirty_bitmap, which change concrete bitmap. Also, to prevent
such mistakes in future, old functions bdrv_(set,reset)_dirty are made
static, for internal block usage.

iotests: Add test for relative backing file names
Sometimes, qemu does not have a filename to work with, so it does not
know which directory to use for a backing file specified by a relative
filename. Add a test which tests that qemu exits with an appropriate
error message.
Additionally, add a test for qemu-img create with a backing filename
relative to the backed image's base directory while omitting the image
size.

block/vmdk: Relative backing file for creation
When a vmdk image is created with a backing file, it is opened to check
whether it is indeed a vmdk file by letting qemu probe it. When doing
so, the backing filename is relative to the image's base directory so it
should be interpreted accordingly.

block: Relative backing file for image creation
Relative backing filenames are always relative to the backed image's
directory; the same applies to image creation. Therefore, if the backing
file has to be opened for determining its size (in case the size has not
been explicitly specified) its filename should be interpreted relative
to the new image's base directory and not relative to qemu's working
directory.

block: JSON filenames and relative backing files
When using a relative backing file name, qemu needs to know the
directory of the top image file. For JSON filenames, such a directory
cannot be easily determined (e.g. how do you determine the directory of
a qcow2 BDS directly on top of a quorum BDS?). Therefore, do not allow
relative filenames for the backing file of BDSs only having a JSON
filename.
Furthermore, BDS::exact_filename should be used whenever possible. If
BDS::filename is not equal to BDS::exact_filename, the former will
always be a JSON object.

checkpatch: Brace handling on multi-line condition
CODING_STYLE states the following about braces around blocks:
> The opening brace is on the line that contains the control flow
> statement that introduces the new block; [...]
This is obviously impossible with multi-line conditions. Therefore,
CODING_STYLE does not make any clear statement about where to put the
opening brace after a multi-line condition.
There is a reason to prefer to place the opening brace on an own line
after such a condition while still placing it on the same line as the
"control flow statement" if possible; that reason is that the last line
of a multi-line condition is indented, in the case of "if", it is often
indented by four spaces, just as much as the first statement in the
block will be indented. This is hard to read as there is no clearly
visible distinction between condition and block. Placing the opening
brace on a separate line solves this issue.
Also, there are cases where placing the opening brace on a separate line
is the only viable option; if the previous line had nearly 80 characters
and splitting it is not desirable, the opening brace is naturally placed
on an own line.
This patch fixes checkpatch.pl to not complain about braces on own lines
if the condition introducing the block spanned more than one line, or if
the previous line had 79 or 80 characters.
Furthermore, the warning about not having braces around a block is fixed
to mind braces not being on the last line of the condition.

net: remove all cleanup methods from NIC NetClientInfos
All NICs have a cleanup function that, in most cases, zeroes the pointer
to the NICState. In some cases, it frees data belonging to the NIC.
However, this function is never called except when exiting from QEMU.
It is not necessary to NULL pointers and free data here; the right place
to do that would be in the device's unrealize function, after calling
qemu_del_nic. Zeroing the NIC multiple times is also wrong for multiqueue
devices.
This cleanup function gets in the way of making the NetClientStates for
the NIC hold an object_ref reference to the object, so get rid of it.

vl: Don't silently change topology when all -smp options were set
QEMU tries to change the "threads" option even if it was explicitly set
in the command-line, and it shouldn't do that.
The right thing to do when all options (cpus, sockets, cores, threds)
are explicitly set is to sanity check them and abort in case they don't
make sense (i.e. when sockets*cores*threads < cpus).

vl.c: fix regression when reading machine type from config file
After 'Machine as QOM' series the machine type input triggers
the creation of the machine class.
If the machine type is set in the configuration file, the machine
class is not updated accordingly and remains the default.
Fixed that by querying the machine options after the configuration
file is loaded.

vfio-pci: Fix interrupt disabling
When disabling MSI/X interrupts the disable functions will leave the
device in INTx mode (when available). This matches how hardware
operates, INTx is enabled unless MSI/X is enabled (DisINTx is handled
separately). Therefore when we really want to disable all interrupts,
such as when removing the device, and we start with the device in
MSI/X mode, we need to pass through INTx on our way to being
completely quiesced.
In well behaved situations, the guest driver will have shutdown the
device and it will start vfio_exitfn() in INTx mode, producing the
desired result. If hot-unplug causes the guest to crash, we may get
the device in MSI/X state, which will leave QEMU with a bogus handler
installed.
Fix this by re-ordering our disable routine so that it should always
finish in VFIO_INT_NONE state, which is what all callers expect.

vfio-pci: Fix BAR size overflow
We use an unsigned int when working with the PCI BAR size, which can
obviously overflow if the BAR is 4GB or larger. This needs to change
to a fixed length uint64_t. A similar issue is possible, though even
more unlikely, when mapping the region above an MSI-X table. The
start of the MSI-X vector table must be below 4GB, but the end, and
therefore the start of the next mapping region, could still land at
4GB.

Follow up patches will change used_length for such blocks at migration,

Device is notified on resize, so it can adjust if necessary.

ssize_t with the %z format string specifier. Since we're printing it
as unsigned hex anyway, cast to size_t to silence the warning.

The GPIO controller lives at IRQ 47, not 43 on real hardware. This is a problem
because IRQ 43 is occupied by the I2C controller which we want to implement

PPC: e500 pci host: Add support for ATMUs
The e500 PCI controller has configurable windows that allow a guest OS
to selectively map parts of the PCI bus space to CPU address space and
to selectively map parts of the CPU address space for DMA requests into
PCI visible address ranges.
So far, we've simply assumed that this mapping is 1:1 and ignored it.
However, the PCICSRBAR (CCSR mapped in PCI bus space) always has to live
inside the first 32bits of address space. This means if we always treat
all mappings as 1:1, this map will collide with our RAM map from the CPU's
point of view.
So this patch adds proper ATMU support which allows us to keep the PCICSRBAR
below 32bits local to the PCI bus and have another, different window to PCI
BARs at the upper end of address space. We leverage this on e500plat though,
mpc8544ds stays virtually 1:1 like it was before, but now also goes via ATMU.
With this patch, I can run guests with lots of RAM and not coincidently access
MSI-X mappings while I really want to access RAM.

PPC: e500: Move CCSR and MMIO space to upper end of address space
On e500 we're basically guaranteed to have 36bits of physical address space
available for our enjoyment. Older chips (like the mpc8544) only had 32bits,
but everything from e500v2 onwards bumped it up.
It's reasonably safe to assume that if you're using the PV machine, your guest
kernel is configured to support 36bit physical address space. So in order to
support more guest RAM, we can move CCSR and other MMIO windows right below the
end of our 36bit address space, just like later SoC versions of e500 do.
With this patch, I'm able to successfully spawn an e500 VM with -m 48G.

virtio-serial: Don't keep a persistent copy of config space
The 'config' field in the VirtIOSerial structure keeps a copy of the virtio
console's config space as visible to the guest, that is to say, in guest
endianness. This is fiddly to maintain, because on some targets, such as
powerpc, the "guest endianness" can change when a new guest OS boots.
In fact, there's no need to maintain such a guest view of config space -
instead we can reconstruct it from host-format data when it is accessed
with get_config.

virtio_serial: Don't use vser->config.max_nr_ports internally
A number of places in the virtio_serial driver retrieve the number of ports
from vser->config.max_nr_ports, which is guest-endian. But for internal
users, we already have a host-endian copy of the number of ports in
vser->serial.max_virtserial_ports. Using that instead of the config field
removes the need for easy-to-forget byteswapping.
In particular this fixes a bug on incoming migration, where we don't adjust
the endianness vser->config correctly, because it hasn't yet been loaded
from the migration stream when virtio_serial_load_device() is called.

pckbd: set bits 2-3-6-7 of the output port by default
OSes typically write 0xdd/0xdf to turn the A20 line off and on. This
has bits 2-3-6-7 on, so that the output port subsection is migrated.
Change the reset value and migration default to include those four
bits, thus avoiding that the subsection is migrated.
This strictly speaking changes guest ABI, but the long time during which
we have not migrated the value means that the guests really do not care
much; so the change is for all machine types.

serial: refine serial_thr_ipending_needed
If the THR interrupt is disabled, there is no need to migrate thr_ipending
because LSR.THRE will be sampled again when the interrupt is enabled.
(This is the behavior that is not documented in the datasheet, but
relied on by Windows!)
Note that in this case IIR will never be 0x2 so, if thr_ipending were
to be one, QEMU would produce the subsection.

hw/arm: pass pristine kernel image to guest firmware over fw_cfg
Introduce the new boolean field "arm_boot_info.firmware_loaded". When this
field is set, it means that the portion of guest DRAM that the VCPU
normally starts to execute, or the pflash chip that the VCPU normally
starts to execute, has been populated by board-specific code with
full-fledged guest firmware code, before the board calls
arm_load_kernel().
Simultaneously, "arm_boot_info.firmware_loaded" guarantees that the board
code has set up the global firmware config instance, for arm_load_kernel()
to find with fw_cfg_find().
Guest kernel (-kernel) and guest firmware (-bios, -pflash) has always been
possible to specify independently on the command line. The following cases
should be considered:
nr -bios -pflash -kernel description
unit#0
-- ------- ------- ------- -------------------------------------------
1 present present absent Board code rejects this case, -bios and
present present present -pflash unit#0 are exclusive. Left intact
by this patch.
2 absent absent present Traditional kernel loading, with qemu's
minimal board firmware. Left intact by this
patch.
3 absent present absent Preexistent case for booting guest firmware
present absent absent loaded with -bios or -pflash. Left intact
by this patch.
4 absent absent absent Preexistent case for not loading any
firmware or kernel up-front. Left intact by
this patch.
5 present absent present New case introduced by this patch: kernel
absent present present image is passed to externally loaded
firmware in unmodified form, using fw_cfg.
An easy way to see that this patch doesn't interfere with existing cases
is to realize that "info->firmware_loaded" is constant zero at this point.
Which makes the "outer" condition unchanged, and the "inner" condition
(with the fw_cfg-related code) dead.

arm: add fw_cfg to "virt" board
fw_cfg already supports exposure over MMIO (used in ppc/mac_newworld.c,
ppc/mac_oldworld.c, sparc/sun4m.c); we can easily add it to the "virt"
board.
Because MMIO access is slow on ARM KVM, we enable the guest, with
fw_cfg_init_mem_wide(), to transfer up to 8 bytes with a single access.
This has been measured to speed up transfers up to 7.5-fold, relative to
single byte data access, on both ARM KVM and x86_64 TCG.
The MMIO register block of fw_cfg is advertized in the device tree. As
base address we pick 0x09020000, which conforms to the comment preceding
"a15memmap": it falls in the miscellaneous device I/O range 128MB..256MB,
and it is aligned at 64KB. The DTB properties follow the documentation in
the Linux source file "Documentation/devicetree/bindings/arm/fw-cfg.txt".
fw_cfg automatically exports a number of files to the guest; for example,
"bootorder" (see fw_cfg_machine_reset()).

fw_cfg_mem: expose the "data_width" property with fw_cfg_init_mem_wide()
We rebase fw_cfg_init_mem() to the new function for compatibility with
current callers.
The behavior of the (big endian) multi-byte data reads is best shown
with a qtest session. Here, we are reading the first six bytes of
the UUID
$ arm-softmmu/qemu-system-arm -M virt -machine accel=qtest \
-qtest stdio -uuid 4600cb32-38ec-4b2f-8acb-81c6ea54f2d8
>>> writew 0x9020008 0x0200
<<< OK
>>> readl 0x9020000
<<< OK 0x000000004600cb32
Remember this is big endian. On big endian machines, it is stored
directly as 0x46 0x00 0xcb 0x32.
On a little endian machine, we have to first swap it, so that it becomes
0x32cb0046. When written to memory, it becomes 0x46 0x00 0xcb 0x32
again.
Reading byte-by-byte works too, of course:
>>> readb 0x9020000
<<< OK 0x0000000000000038
>>> readb 0x9020000
<<< OK 0x00000000000000ec
Here only a single byte is read at a time, so they are read in order
similar to the 1-byte data port that is already in PPC and SPARC
machines.

fw_cfg_mem: introduce the "data_width" property
The "data_width" property is capable of changing the maximum valid access
size to the MMIO data register, and resizes the memory region similarly,
at device realization time.
The default value of "data_memwidth" is set so that we don't yet diverge
from "fw_cfg_data_mem_ops".
Most of the fw_cfg_mem users will stick with the default, and for them we
should continue using the statically allocated "fw_cfg_data_mem_ops". This
is beneficial for debugging because gdb can resolve pointers referencing
static objects to the names of those objects.

fw_cfg: hard separation between the MMIO and I/O port mappings
We are going to introduce a wide data register for fw_cfg, but only for
the MMIO mapped device. The wide data register will also require the
tightening of endiannesses.
However we don't want to touch the I/O port mapped fw_cfg device at all.
Currently QEMU provides a single fw_cfg device type that can handle both
I/O port and MMIO mapping. This flexibility is not actually exploited by
any board in the tree, but it renders restricting the above changes to
MMIO very hard.
Therefore, let's derive two classes from TYPE_FW_CFG: TYPE_FW_CFG_IO and
TYPE_FW_CFG_MEM.
TYPE_FW_CFG_IO incorporates the base I/O port and the related combined
MemoryRegion. (NB: all boards in the tree that use the I/O port mapped
flavor opt for the combined mapping; that is, when the data port overlays
the high address byte of the selector port. Therefore we can drop the
capability to map those I/O ports separately.)
TYPE_FW_CFG_MEM incorporates the base addresses for the MMIO selector and
data registers, and their respective MemoryRegions.
The "realize" and "props" class members are specific to each new derived
class, and become unused for the base class. The base class retains the
"reset" member and the "vmsd" member, because the reset functionality and
the set of migrated data are not specific to the mapping.
The new functions fw_cfg_init_io() and fw_cfg_init_mem() expose the
possible mappings in separation. For now fw_cfg_init() is retained as a
compatibility shim that enforces the above assumptions.

using the generic ARM cpu_arm_init function to doing it inline. This is
necessary in order to allow CPU configuration changes to occur between CPU
instance initialization and realization. Specifically, this change is in
preparation for disabling CPU EL3 support.

target-arm: Set CPU has_el3 prop during virt init
Adds setting of the CPU has_el3 property based on the virt machine
secure state property during initialization. This enables/disables EL3
state during start-up. Changes include adding an additional secure state
boolean during virt CPU initialization. Also disables the ARM secure boot

target-arm: Add arm_boot_info secure_boot control
Adds the secure_boot boolean field to the arm_boot_info descriptor. This
fields is used to indicate whether Linux should boot into secure or non-secure
state if the ARM EL3 feature is enabled. The default is to leave the CPU in an
unaltered reset state. On EL3 enabled systems, the reset state is secure and
can be overridden by setting the added field to false.

Merge of the v8_el2_cp_reginfo and el3_cp_reginfo ARMCPRegInfo lists.
Previously, some EL3 registers were restricted to the ARMv8 list under the
impression that they were not needed on ARMv7. However, this is not the case
as the ARMv7/32-bit variants rely on the ARMv8/64-bit variants to handle
migration and reset. For this reason they must always exist.

audio: Don't free hw resources until after hw backend is stopped
When stopping an audio voice, call the audio backend's fini
method before calling audio_pcm_hw_free_resources_ rather than
afterwards. This allows backends which use helper threads (like
pulseaudio) to terminate those threads before the conv_buf or
mix_buf are freed and avoids race conditions where the helper
may access a NULL pointer or freed memory.

exec: change default exception_index value for migration to -1
In QEMU 2.2 the exception_index value was added to the migration stream
through a subsection. The default was set to 0, which is wrong and
should have been -1.
However, 2.2 does not have commit e511b4d (cpu-exec: reset exception_index
correctly, 2014-11-26), hence in 2.2 the exception_index is never used
and is set to -1 on the next call to cpu_exec. So we can change the
migration stream to make the default -1. The effects are:
- 2.2.1 -> 2.2.0: cpu->exception_index set incorrectly to 0 if it
were -1 on the source; then reset to -1 in cpu_exec. This is TCG
only; KVM does not use exception_index.
- 2.2.0 -> 2.2.1: cpu->exception_index set incorrectly to -1 if it
were 0 on the source; but it would be reset to -1 in cpu_exec anyway.
This is TCG only; KVM does not use exception_index.
- 2.2.1 -> 2.1: two bugs fixed: 1) can migrate backwards if
cpu->exception_index is set to -1; 2) should not migrate backwards
(but 2.2.0 allows it) if cpu->exception_index is set to 0
- 2.2.0 -> 2.3.0: 2.2.0 will send the subsection unnecessarily if
exception_index is -1, but that is not a problem. 2.3.0 will set
cpu->exception_index to -1 if it is 0 on the source, but this would
be anyway a problem for 2.2.0 -> 2.2.x migration (due to lack of
commit e511b4d in 2.2.x) so we can ignore it
- 2.2.1 -> 2.3.0: everything works.
In addition, play it safe and never send the subsection unless TCG
is in use. KVM does not use exception_index (PPC KVM stores values
in it for use in the subsequent call to ppc_cpu_do_interrupt, but
does not need it as soon as kvm_handle_debug returns). Xen and
qtest do not run any code for the CPU at all.

net: Use g_new() & friends where that makes obvious sense
g_new(T, n) is neater than g_malloc(sizeof(T) * n). It's also safer,
for two reasons. One, it catches multiplication overflowing size_t.
Two, it returns T * rather than void *, which lets the compiler catch
more type errors.

net: don't use set/get_pointer() in set/get_netdev()
Commit 1ceef9f27359cbe92ef124bf74de6f792e71f6fb (net: multiqueue
support) tries to use set_pointer() and get_pointer() to set and get
NICPeers which is not a pointer defined in DEFINE_PROP_NETDEV. This
trick works but result a unclean and fragile implementation (e.g
print_netdev and parse_netdev).
This patch solves this issue by not using set/get_pinter() and set and
get netdev directly in set_netdev() and get_netdev(). After this the
parse_netdev() and print_netdev() were no longer used and dropped from
the source.

sdl2: Work around SDL2 SDL_ShowWindow() bug
Apparently it is possible for X to send an event to a hidden SDL2
window, leading to SDL2 believing it is now shown. SDL2 will pass the
SDL_WINDOWEVENT_SHOWN message to the application without actually
showing the window; the problem is that the next SDL_ShowWindow() will
be a no-op because SDL2 assumes the window is already shown.
The correct way to react to SDL_WINDOWEVENT_SHOWN would be to clear
scon->hidden (analogous for SDL_WINDOWEVENT_HIDDEN). However, due to the
window not actually being shown, this will somehow not be correct after
all.
Therefore, just hide the window on SDL_WINDOWEVENT_SHOWN if it is
supposed to be hidden (and analogous for SDL_WINDOWEVENT_HIDDEN).

sdl2: Use correct sdl2_console for window events
SDL_PollEvent() polls events for all windows; therefore,
sdl2_poll_events() will poll the events for all windows and not only for
the one identified by the given sdl2_console.
This should be considered in handle_windowevent(): The window affected
by the event is not necessarily the one identified by the sdl2_console
object given to sdl2_poll_events(), but the one identified by
ev->window.windowID.

sdl2: overhaul window size handling
Split do_sdl_resize function (which does alot more than just resizing)

Fix SDL_Renderer handling: must be guest display size not host window

Make fullscreen actually enter fullscreen mode and simplify the code.
There is no need to store the original window size, the window manager

So it's very difficult to find LOG_UNIMP message.
The mips_cpu_handle_mmu_fault() messages appear on enabling ANY

Adding separate log category for *_cpu_handle_mmu_fault()

spice: fix memory leak
If errors happen for middle items of channel_list,
qmp_query_spice_channels() returns NULL, and the variable
cur_item going out of scope leaks the storage it points to.
The flag is a compatibility thing for older spice-server
versions. Meanwhile our minimum spice version requirement is
new enough that we should never ever see this error, and if we
do something went very seriously wrong. Let's using assert()
instead of returning NULL to avoid a memory leak.

target-mips: Fix CP0.Config3.ISAOnExc write accesses
Fix CP0.Config3.ISAOnExc write accesses on microMIPS processors. This
bit is mandatory for any processor that implements the microMIPS
instruction set. This bit is r/w for processors that implement both the
standard MIPS and the microMIPS instruction set. This bit is r/o and
hardwired to 1 if only the microMIPS instruction set is implemented.
There is no other bit ever writable in CP0.Config3 so defining a
corresponding `CP0_Config3_rw_bitmask' member in `CPUMIPSState' is I
think an overkill. Therefore make the ability to write the bit rely on
the presence of ASE_MICROMIPS set in the instruction flags.
The read-only case of the microMIPS instruction set being implemented
only can be added when we add support for such a configuration. We do
not currently have such support, we have no instruction flag that would
control the presence of the standard MIPS instruction set nor any
associated code in instruction decoding.
This change is needed to boot a microMIPS Linux kernel successfully,
otherwise it hangs early on as interrupts are enabled and then the
exception handler invoked loops as its first instruction is interpreted
in the wrong execution mode and triggers another exception right away.
And then over and over again.
We already check the current setting of the CP0.Config3.ISAOnExc in
`set_hflags_for_handler' to set the ISA bit correctly on the exception
handler entry so it is the ability to set it that is missing only.

target-mips: Fix the 64-bit case for microMIPS MOVE16 and MOVEP
Fix microMIPS MOVE16 and MOVEP instructions on 64-bit processors by
using register addition operations.
This copies the approach taken with MIPS16 MOVE instructions (I8_MOV32R
and I8_MOVR32 opcodes) and follows the observation that OPC_ADDU expands
to tcg_gen_mov_tl whenever `rt' is 0 and `rs' is not, therefore copying
`rs' to `rd' verbatim. This is not the case with OPC_ADDIU where a
sign-extension from bit #31 is made, unless in the uninteresting case of
`rs' being 0, losing the upper 32 bits of the value copied for any
proper 64-bit values.
This also serves as an optimization as one op is produced in generated
code rather than two (again, unless `rs' is 0, where it doesn't change
anything).

target-mips: Add M14K and M14Kc MIPS32r2 microMIPS processors
Add the M14K and M14Kc processors from MIPS Technologies that are the
original implementation of the microMIPS ISA. They are dual instruction
set processors, implementing both the microMIPS and the standard MIPSr32
ISA.
These processors correspond to the M4K and 4KEc CPUs respectively,
except with support for the microMIPS instruction set added, support for
the MCU ASE added and two extra interrupt lines, making a total of 8
hardware interrupts plus 2 software interrupts. The remaining parts of
the microarchitecture, in particular the pipeline, stayed unchanged.
The presence of the microMIPS ASE is is reflected in the configuration
added. We currently have no support for the MCU ASE, including in
particular the ACLR, ASET and IRET instructions in either encoding, and
we have no support for the extra interrupt lines, including bits in
CP0.Status and CP0.Cause registers, so these features are not marked,
making our support diverge from real hardware.

target-mips: Add 5KEc and 5KEf MIPS64r2 processors
Add the 5KEc and 5KEf processors from MIPS Technologies that are the
original implementation of the MIPS64r2 ISA.
Silicon for these processors has never been taped out and no soft cores
were released even. They do exist though, a CP0.PRId value has been
assigned and experimental RTLs produced at the time the MIPS64r2 ISA has
been finalized. The settings introduced here faithfully reproduce that
hardware.
As far the implementation goes these processors are the same as the 5Kc
and the 5Kf CPUs respectively, except implementing the MIPS64r2 rather
than the original MIPS64 instruction set. There must have been some
updates to the CP0 architecture as mandated by the ISA, such as the
addition of the EBase register, although I am not sure about the exact
details, no documentation has ever been produced for these processors.
The remaining parts of the microarchitecture, in particular the
pipeline, stayed unchanged. Or to put it another way, the difference
between a 5K and a 5KE CPU corresponds to one between a 4K and a 4KE
CPU, except for the 64-bit rather than 32-bit ISA.

Start migrating migration code into a migration directory
The migration code now occupies a fair chunk of the top level .c
files, it seems time to give it it's own directory.
I've not touched:
arch_init.c - that's mostly RAM migration but has a few random other
bits
savevm.c - because it's built target specific
This is purely a code move; no code has changed.
- it fails checkpatch because of old violations, it feels safer
to keep this as purely a move and fix those at some mythical future
date.
The xbzrle and vmstate tests are now only run for softmmu builds
since they require files in the migrate/ directory which is only built
for softmmu.

Remove the virtual methods and replace them with direct calls to the

serial: only resample THR interrupt on rising edge of IER.THRI
There is disagreement on whether LSR.THRE should be resampled when
IER.THRI goes from 1 to 1. Bochs only does it if IER.THRI goes from 0
to 1; PCE does it even if IER.THRI is unchanged. But the Windows driver
seems to always go from 1 to 0 and back to 1, so do things in agreement
with Bochs, because the handling of thr_ipending was reported in 2010
(https://lists.gnu.org/archive/html/qemu-devel/2010-03/msg01914.html)
as breaking DR-DOS Plus.

serial: update LSR on enabling/disabling FIFOs
When the transmit FIFO is emptied or enabled, the transmitter
hold register is empty. When it is disabled, it is also emptied and
in addition the previous contents of the transmitter hold register
are discarded. In either case, the THRE bit in LSR must be set and
THRI raised.
When the receive FIFO is emptied or enabled, the data ready and break
bits must be cleared in LSR. Likewise when the receive FIFO is disabled.

serial: clean up THRE/TEMT handling
- assert TEMT is cleared before sending a character; we'll get one from
TSR if tsr_retry > 0, from the FIFO or THR otherwise
- assert THRE cleared and FIFO not empty (if enabled) before fetching a
character to send. This effectively reverts dffacd46, but the check
makes no sense and commit f702e62 (serial: change retry logic to avoid
concurrency, 2014-07-11) must have made it unnecessary. The commit
message for f702e62 talks about multiple calls to qemu_chr_fe_add_watch
triggering s->tsr_retry >= MAX_XMIT_RETRY, but other failures were
possible. For example, if you have multiple calls, the subsequent ones
will see s->tsr_retry == 0 and will find THRE and/or TEMT on entry.
- for clarity, raise THRI immediately after the code sets THRE
- check THRE to see if another character has to be sent. This makes
the assertions more obvious and also means TEMT has to be set as soon as
the loop ends. It makes the loop send both TSR and THR if flow-control
happens in non-FIFO mode. Previously, THR would be lost.
- clear TEMT together with THRE even in the non-FIFO case
The last two items are bugfixes, but they were just found by inspection
and do not squash known bugs.

serial: reset thri_pending on IER writes with THRI=0
This is responsible for failure of migration from 2.2 to 2.1, because
thr_ipending is always one in practice.
serial.c is setting thr_ipending unconditionally. However, thr_ipending
is not used at all if THRI=0, and it will be overwritten again the next
time THRE or THRI changes. For that reason, we can set thr_ipending to
zero every time THRI is reset.
There is disagreement on whether LSR.THRE should be resampled when IER.THRI
goes from 1 to 1. This patch does not touch the code, leaving that for
QEMU 2.3+.
This has no semantic change and is enough to fix migration in the common
case where the interrupt is not pending or is reported in IIR. It does not
change the migration format, so 2.2.0 -> 2.1 will remain broken but we
can fix 2.2.1 -> 2.1 without breaking 2.2.1 <-> 2.2.0.
The case that remains broken (the one in which the subsection is strictly
necessary) is when THRE=1, the THRI interrupt has *not* been acknowledged
yet, and a higher-priority interrupt comes. In this case, you need the
subsection to tell the source that the lower-priority THRI interrupt is
pending. The subsection's breakage of migration, in this case, prevents
continuing the VM on the destination with an invalid state.

linuxboot: fix loading old kernels
Old kernels that used high memory only allowed the initrd to be in the
first 896MB of memory. If you load the initrd above, they complain
that "initrd extends beyond end of memory".
In order to fix this, while not breaking machines with small amounts
of memory fixed by cdebec5 (linuxboot: compute initrd loading address,
2014-10-06), we need to distinguish two cases. If pc.c placed the
initrd at end of memory, use the new algorithm based on the e801
memory map. If instead pc.c placed the initrd at the maximum address
specified by the bzImage, leave it there.
The only interesting part is that the low-memory info block is now
loaded very early, in real mode, and thus the 32-bit address has
to be converted into a real mode segment. The initrd address is
also patched in the info block before entering real mode, it is
simpler that way.
This fixes booting the RHEL4.8 32-bit installation image with 1GB
of RAM.

cpus: make icount warp behave well with respect to stop/cont
This patch makes icount warp use the new QEMU_CLOCK_VIRTUAL_RT clock.
This way, icount's QEMU_CLOCK_VIRTUAL will never count time during which
the virtual machine is stopped.

cpu-exec: fix cpu_exec_nocache
In icount mode cpu_exec_nocache function is used to execute part of the
existing TB. At the end of cpu_exec_nocache newly created TB is deleted.
Sometimes io_read function needs to recompile current TB and restart TB
lookup and execution. After that tb_find_fast function finds old (bigger)
TB again. This TB cannot be executed (because icount is not big enough)
and cpu_exec_nocache is called again. Such a loop continues over and over.
This patch deletes old TB and avoids finding it in the TB cache.

target-i386: fix icount processing for repz instructions
TCG generates optimized code for i386 repz instructions in single step mode.
It means that when ecx becomes 0, execution of the string instruction breaks
immediately without an additional iteration for ecx==0 (which will only check
ecx and set the flags). Omitting this iteration leads to different
instructions counting in singlestep mode and in normal execution.
This patch disables optimization of this last iteration for icount mode
which should be deterministic.

linux-aio: track whether the queue is blocked
Avoid that unplug submits requests when io_submit reported that it
couldn't accept more; at the same time, try more io_submit calls if it
could handle the whole set of requests that were passed, so that the
"blocked" flag is reset as soon as possible.
After the previous patch, laio_submit already tried to avoid submitting
requests to a blocked queue, by comparing s->io_q.idx with "==" instead
of the more natural ">=". Switch to the simpler expression now that we
have the "blocked" flag.

qemu-io: Add sigraise command
abort() has the sometimes undesirable side-effect of generating a core
dump. If that is not needed, SIGKILL has the same effect of abruptly
crash qemu; without a core dump.
Thus, -c abort is not always useful to simulate a qemu-io crash;
therefore, this patch adds a new sigraise command which allows raising
a signal.

block: vhdx - change .vhdx_create default block state to ZERO
The VHDX spec specifies that the default new block state is
PAYLOAD_BLOCK_NOT_PRESENT for a dynamic VHDX image, and
PAYLOAD_BLOCK_FULLY_PRESENT for a fixed VHDX image.
However, in order to create space-efficient VHDX images with qemu-img
convert, it is desirable to be able to set has_zero_init to true for
VHDX.
There is currently an option when creating VHDX images, to use block
state ZERO for new blocks. However, this currently defaults to 'off'.
In order to be able to eventually set has_zero_init to true for VHDX,
this needs to default to 'on'.
This patch changes the default to 'on', and provides some help
information to warn against setting it to 'off' when using qemu-img
convert.
[Max Reitz pointed out that a full stop was missing at the end of the
VHDX_BLOCK_OPT_ZERO option help text. I have added it.

The 0.95 VHDX spec defined PAYLOAD_BLOCK_UNMAPPED to be 5. The 1.00
VHDX spec redefines PAYLOAD_BLOCK_UNMAPPED to be 3 instead.
The original value of 5 is now an undefined state in the spec, but it

This way, we can maintain compatibility with any images out in the wild

If vmdk blindly tries to use path_combine() using bs->file->filename as

file names when calling bdrv_open(). It is better to only try
bs->file->exact_filename; if that is empty, bs->file->filename will be
useless for path_combine() and an error should be emitted (containing
bs->file->filename because desc_file_path (which is
bs->file->exact_filename) is empty).

target-arm/kvm: make reg sync code common between kvm32/64
Before we launch a guest we query KVM for the list of "co-processor"
registers it knows about. This is used to synchronize system
register state for the bulk of coprocessor/system registers.
Move this code from the 32-bit specific vcpu init function into
a common routine and call it also from the 64-bit vcpu init.
This allows system registers to migrate correctly when using
KVM, and also permits QEMU code to see the current KVM register
state (which will be needed to support big-endian guests, since
the virtio endianness callback must check for some system register
settings).
Since vcpu reset also has to sync registers, we move the
32 bit kvm_arm_reset_vcpu() into common code as well and
share it with the 64 bit version.

Here we simply remove the 'if (binfo->get_dtb)' to satisfy coverity.

hw/arm/realview.c: Fix memory leak in realview_init()
Variable 'ram_lo' is allocated unconditionally, but used only in some cases.
When it is unused pointer will be lost at function exit, resulting in a
memory leak. Allocate memory for 'ram_lo' only if it is needed.
Valgrind output:
==16879== 240 bytes in 1 blocks are definitely lost in loss record 6,033 of 7,018

target-arm: add banked register accessors
If EL3 is in AArch32 state certain cp registers are banked (secure and
non-secure instance). When reading or writing to coprocessor registers
the following macros can be used.
- A32_BANKED macros are used for choosing the banked register based on provided
input security argument. This macro is used to choose the bank during
translation of MRC/MCR instructions that are dependent on something other
than the current secure state.
- A32_BANKED_CURRENT macros are used for choosing the banked register based on
current secure state. This is NOT to be used for choosing the bank used
during translation as it breaks monitor mode.
If EL3 is operating in AArch64 state coprocessor registers are not
banked anymore. The macros use the non-secure instance (_ns) in this
case, which is architecturally mapped to the AArch64 EL register.

Date: Thu Dec 11 12:07:48 2014 +0000
Add the "-semihosting-config" option.
The usual semihosting behaviour is to process the system calls locally and
return; unfortuantelly the initial implementation dinamically changed the
target to GDB during debug sessions, which, for the usual arm-none-eabi-gdb,
is not implemented. The result was that during debug sessions the semihosting
calls were discarded.
This patch adds a configuration variable and an option to set it on the
command line:
-semihosting-config [enable=on|off,]target=native|gdb|auto
This option enables semihosting and defines where the semihosting calls will
be addressed, to QEMU ('native') or to GDB ('gdb'). The default is auto, which
means 'gdb' during debug sessions and 'native' otherwise.

(ADP_Stopped_ApplicationExit), all other codes should return non-zero
exit codes.
This patch checks if the application code passed via TARGET_SYS_EXIT is
ADP_Stopped_ApplicationExit, and return 0, otherwise return 1.

vmdk: Use g_random_int to generate CID
This replaces two "time(NULL)" invocations with "g_random_int()".
According to VMDK spec, CID "is a random 32‐bit value updated the first
time the content of the virtual disk is modified after the virtual disk
is opened". Using "seconds since epoch" is just a "lame way" to generate
it, and not completely safe because of the low precision.

anything can be amended in the first place. Check that this holds true

this is not something that should really work; qemu-img should check
whether the parameter for the -f option (and -O for convert) is indeed a
format, and error out if it is not. Therefore, I am not making it an
iotest.

ide: Check validity of logical block size
Our IDE emulation can't handle logical block sizes other than 512. Check
for it.
The original assumption was that other values would silently be ignored
(which is bad enough), but it's not quite true: The physical block size
is exposed in IDENTIFY DEVICE as a multiple of the logical block size.
Setting a logical block size therefore also corrupts the physical block
size (4096/4096 doesn't silently downgrade to 4096/512, but 512/512).

Not looking up the backing file driver in bdrv_open_backing_file(), but

blockdev: acquire AioContext in QMP 'transaction' actions
The transaction QMP command performs operations atomically on a group of
drives. This command needs to acquire AioContext in order to work
safely when virtio-blk dataplane IOThreads are accessing drives.
The transactional nature of the command means that actions are split
into prepare, commit, abort, and clean functions. Acquire the
AioContext in prepare and don't release it until one of the other
functions is called. This prevents the IOThread from running the
AioContext before the transaction has completed.

raw: Prohibit dangerous writes for probed images
If the user neglects to specify the image format, QEMU probes the
image to guess it automatically, for convenience.
Relying on format probing is insecure for raw images (CVE-2008-2004).
If the guest writes a suitable header to the device, the next probe
will recognize a format chosen by the guest. A malicious guest can
abuse this to gain access to host files, e.g. by crafting a QCOW2
header with backing file /etc/shadow.
Commit 1e72d3b (April 2008) provided -drive parameter format to let
users disable probing. Commit f965509 (March 2009) extended QCOW2 to
optionally store the backing file format, to let users disable backing
file probing. QED has had a flag to suppress probing since the
beginning (2010), set whenever a raw backing file is assigned.
All of these additions that allow to avoid format probing have to be
specified explicitly. The default still allows the attack.
In order to fix this, commit 79368c8 (July 2010) put probed raw images
in a restricted mode, in which they wouldn't be able to overwrite the
first few bytes of the image so that they would identify as a different
image. If a write to the first sector would write one of the signatures
of another driver, qemu would instead zero out the first four bytes.
This patch was later reverted in commit 8b33d9e (September 2010) because
it didn't get the handling of unaligned qiov members right.
Today's block layer that is based on coroutines and has qiov utility
functions makes it much easier to get this functionality right, so this
patch implements it.
The other differences of this patch to the old one are that it doesn't
silently write something different than the guest requested by zeroing
out some bytes (it fails the request instead) and that it doesn't
maintain a list of signatures in the raw driver (it calls the usual
probe function instead).
Note that this change doesn't introduce new breakage for false positive
cases where the guest legitimately writes data into the first sector
that matches the signatures of an image format (e.g. for nested virt):
These cases were broken before, only the failure mode changes from
corruption after the next restart (when the wrong format is probed) to
failing the problematic write request.
Also note that like in the original patch, the restrictions only apply
if the image format has been guessed by probing. Explicitly specifying a
format allows guests to write anything they like.

The only image format driver that even potentially accesses anything

seems to come first and will be well within the first 512 bytes, too.

qemu-nbd: Use BlockBackend where reasonable
Because qemu-nbd creates the BlockBackend by itself, it should create
the according BlockDriverState tree by itself as well; that means, it
has call bdrv_open() on its own. This is one of the places where
qemu-nbd still needs to use a BlockDriverState directly (the root BDS
below the BB); other places are the configuration of zero detection
(which may be lifted into the BB eventually, but is not yet) and
temporarily loading a snapshot.
Everywhere else, though, qemu-nbd can and thus should use BlockBackend.

block: Add blk_add_close_notifier() for BB
Adding something like a "delete notifier" to a BlockBackend would not
make much sense, because whoever is interested in registering there will
probably hold a reference to that BlockBackend; therefore, the notifier
will never be called (or only when the notifiee already relinquished its
reference and thus most probably is no longer interested in that
notification).
Therefore, this patch just passes through the close notifier interface
of the root BDS. This will be called when the device is ejected, for
instance, and therefore does make sense.

block: Add AioContextNotifier functions to BB
Because all BlockDriverStates behind a single BlockBackend reside in a
single AioContext, it is fine to just pass these functions
(blk_add_aio_context_notifier() and blk_remove_aio_context_notifier())
through to the root BlockDriverState.

There are already some blk_aio_* functions, so we might as well have
blk_co_* functions (as far as we need them). This patch adds
blk_co_flush(), blk_co_discard(), and also blk_invalidate_cache() (which
is not a blk_co_* function but is needed nonetheless).

ahci: avoid #ifdef DEBUG_AHCI bitrot
Debug code using #ifdef is susceptible to bitrot because the compiler
never checks the debug code.
This is easy to avoid, change the DPRINTF() macro to use if (DEBUG_AHCI)
and always give it a 0 or 1 value.
This also allows us to drop an #ifdef DEBUG_AHCI in ahci_start_dma()
since the compiler can now see the local variable is used.
The motivation for this change is a recent DEBUG_AHCI build failure due
to an outdated DPRINTF() format string. From now on the compiler will
catch these errors.

blkdebug: Simplify and improve filename generation
Instead of actually recreating the options from scratch, just reuse the
options given for creating the BDS, which are the configuration file
name and additional options. In case there are no additional options we
can thus create a plain filename.
This obviously results in a different output for qemu-iotest 099 which
exactly tests this filename generation. Fix it up as well.

target-s390x: fix possible out of bounds read
Array index starts at 0, so the valid index of ext_queue array,
io_queue array, mchk_queue array should be MAX_EXT_QUEUE - 1,
MAX_IO_QUEUE - 1, MAX_MCHK_QUEUE - 1.
The original checks missed the invalid bound value, which will lead
possible out of bounds read in the follow codes.
